The Venerable 4 Speed Clutch - Part 1

Harley Davidson used the same clutch on all of it's Big Twin models from 1941 to 1984, with only a few changes. These days it is commonly referred to as a 4 speed clutch even though it continued in use on the early 5 speed transmissions. These days it is commonly renounced as being a piece of junk. I am sure that helps to sell more modern clutch conversions, but the clutch itself hardly deserves the assessment.

The complaints generally go something like this: "The bike still tries to creep forward even with the clutch lever pulled all the way in." The clutch is grabby." "It's hard to get into first gear." "It's hard to find neutral."

A few items are all it generally takes to make the clutch work "as good as new." A few more trick can make it better than new.

Here are some common problems and solutions.

  1. Oil soaked and gummy fiber plates - solution: replace the discs. There have been a lot of "stop gap" measures to avoid replacing the fibers over the years such as baking to draw the oil out, spraying with brake cleaner and such. None of the work particularly well. Buy even the cheapest replacement fibers you can get, and you will be much more satisfied.

  2. Glazed fiber plates - solution: same as above, replace the discs. A stop gap measure is to "rough up" the surface, usually by rubbing them on some concrete

  3. Primary chain or belt misaligned - solution: align. If your clutch basket is inboard in relation to the engine sprocket, when you pull in the clutch, the basket will naturally move out to align with the engine sprocket. This takes up the free space between the plates that pulling in the clutch was supposed to give, resulting in a dragging clutch.

  4. Primary chain or belt too tight - solution: adjust. Very similar to number 3 above. Obviously adjusting a chain is pretty easy. Some belt drives are non adjustable due to rigid primary housings. Consult the manufacturer as to why his product doesn't fit correctly. I am sure he will tell you that it is the first time he has heard of this problem. Then switch to a chain.

  5. Clutch hub studs grooved - solution: replace the studs or the clutch hub assembly. This manifests itself in a dragging clutch due to the fiber discs (which have the small holes that the studs go through) being hindered from moving due to the grooves. If you choose to repair this by replacing studs, you can convert it to a 5 stud at the same time. The only advantage to a 5 stud is that allows a finer adjustment for the springs.

  6. Clutch basket dogs grooved - solution: replace dogs or basket.This is similar to #5 above, except that it is the steel plates that have worn grooves into the dog s on the basket. This is far less common than grooved studs.

  7. Clutch pressure plate warped -solution: replace. If the pressure plate is not flat, it will be very difficult to adjust the clutch so that the plate releases evenly. The best solution to this is to upgrade to an aftermarket aluminum pressure plate, often referred to as a precision pressure plate.

  8. Clutch springs out of adjustment - solution: adjust. This can show up in a couple of ways. Springs that are not adjusted with enough tension can slip. Springs that are adjusted too tightly may coilbind before there has been enough movement of the pressure plate to allow full disengagement. The most prevalent problem, though, is not adjusting the springs for even pressure. This can cause the cause the clutch to be grabby or to drag. Your service manual tells you to adjust the three nuts on the clutch hub studs so that there is 1 inch between the stock pressure plate and the inside of the spring retainer. That is a good starting point, but for best results you need to pull in the clutch while watching the pressure plate and adjust those nuts so that the pressure plate comes out evenly. In other words, if one side of the plate starts to move before the other, adjust the nut on that side in a half turn or two until the pressure plate comes out evenly. Turn the pressure plate to different points in its rotation and double check this release. This is a major cause of a grabby clutch, and is easy to remedy!

  9. Clutch pushrod and adjusting screw not having "squared off" ends - solution: machine them or replace them. This fits hand in hand with #8 above. Somewhere along the line, someone came up with the bright idea of making a clutch adjusting screw (the screw that goes into the center of the pressure plate) with a ball bearing in the end. Obviously they thought this would be a plus if you did not adjust the clutch with enough free play. The problem is that it aggravates the problem of the pressure plate not releasing evenly as described above. Picture the difference between balancing a 5 gallon pail on top of another 5 gallon pail (with lid). Now picture balancing the 5 gallon pail on a basketball. Any small difference in spring pressure from one side of the pressure plate to the other will be magnified by "balancing it on an adjusting screw with a ball on the end of it. Usually the pushrod itself will have an end that is already "squared off."

  10. Insufficient travel of pressure plate for full disengagement. solution: restore full travel. This can be as simple as adjusting the clutch free play. Obviously if your clutch lever moves an excess amount before it starts to move the pressure plate, it may hit its full travel before the pressure plate has moved far enough to fully disengage the clutch. It is best to unhook the clutch cable, and then adjust the screw in the center of the pressure plate. In most cases this can be accomplished by turning the screw in until it lightly bottoms, and then back off a quarter turn. Then go back, hook the cable up, and adjust the free play at the lever. You must leave some free play or the throw out bearing will burn up. This is all it should take if all else is in good stock working order. There are a couple of other possible issues though. One is if you have a set of the really thick aftermarket grips that are on the market today. Your clutch lever will bottom out on this grip before it traveled as far as it would with the stock grip. (when I drag raced, I wouldn't run any grip at all on the clutch side just to add a little more travel) Another potential problem is in some of the clutch cables I have seen. In an effort to make clutch cables more "flexible" some of them have been "woven" with wires that are not stiff enough. I have seen cables that actually stretch somewhat as the lever is pulled, and then relax again when the lever is released. Sort of like using a big spring to release your clutch.

Well, that pretty much covers the common causes and solutions for the 4 speed clutch problems, at least those that have come to mind. I may remember more later. In a future post I intend to cover some tricks and tips for high performance use. All in all, great performance can be realized without resorting to replacement of this durable clutch with one of a different design.

Church and the Gospel

How "Church" should be done is a subject that is at the forefront of more than just a few disagreements among Christians for the last .... well for the last 2000 years. In light of that fact, it should come as no surprise to us that it comes up often today.

One question that has come to my attention recently pertains to who the worship service should be "aimed" towards. It may be that the "seeker sensitive" service that was all the rage for quite some time now, may be on its way out in "modern" churches. Some would argue that the seeker sensitive service missed the mark, because it was aimed at the wrong target. A church service should be for the Christian, not for the person who is trying to decide whether or not they should become one, they say.

Frankly, I agree with that assessment, to a point. Anyone who has followed this blog for any time probably realizes that I am a conservative Baptist (and I hope that term has no connotations that I am unaware of). As such I don't have much time for the whole seeker sensitive thing. From what I have seen of it, the seeker sensitive church, to a large extent, has come down to luring in people (who are interested in spiritual things) by promising to be relevant and entertaining, and to enhance their life, but never really getting to the subject of sin and the answer to sin.

Now a second way of looking at a church service has more merit, in that a church is an assembly, and a Church (note the capital C) is an assembly of believers (and being a Baptist, I would add baptized believers). John 4:23 says "But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him." Hence a church service, or worship service would rightly focus on those who are already Christians.

So far, this second type of service is a pretty good description of ValleyView Baptist over the past year and a half that my wife and I have been members. Nearly all of the sermons from our pastor (who has recently moved on to another church) were basically aimed toward edifying the body of Christ. While the subject of sin and the gospel were certainly not avoided, neither were they stressed because after all, those receiving the sermons were professed Christians. This is NOT meant in any way to reflect adversely on him; the fact is we miss and love him dearly.

In this vein of "doing church" specifically for the Christian, I recently heard a pastor say that he no longer invites people to church. He said he does his evangelism only after getting to know someone. Some of you may agree with him. Others may be shocked. Me? Well ....

I have to agree that there is no point to inviting someone to your church if the gospel is not going to be preached. And just as important, if sin is never going to be mentioned, there is no point in preaching the gospel, since the man with a terminal illness who doesn't know it, will have little use for a life saving medicine. Wasn't that a major problem with the seeker sensitive service? So, by all means, if you are not going to preach about sin and the gospel, don't invite unbelievers to your church. But I do believe that may come with its own issues.

I have heard (from more than one source) that young people attending Christian colleges, in many cases, cannot even articulate the basic tenants of the faith. Do you think there is a chance that many of these never really were born again? After all, if they grew up in the typical seeker sensitive church, they may have never been told of their desperate need of a saviour. But does this not also apply to the child who grew up in a church where "church" was done just for Christians?

Let me tell you a little story that helps explain how I come down on this issue. Nearly 10 years ago, my wife and I attended a church service due directly to an invitation in the form of literature brought to our door. No, not Jehovah's Witness or Mormon; some Baptist's go door to door also.

This was a fairly small church. Small enough that new faces were noticed by everyone, not least by the pastor. In retrospect, I have no doubt that the pastor of that little Baptist Church modified his sermon "on the fly" in order to present the gospel to these strangers. I would bet that he did the same the following Sunday. By the third consecutive Sunday, he probably expected us and prepared accordingly.

If you haven't already guessed, that chain of events is how our most merciful God chose to save me. Maybe that prejudiced me, but I certainly would never feel shorted by a pastor who felt the need to preach a little hell fire and damnation topped off with the good news in place of an edifying sermon. In fact, I believe that a little more preaching of the law (which identifies sin) and the gospel would be a God honoring addition to any way that you might chose to "do church."

One last point. If you, as a pastor, seldom preach the law and the gospel, just where do you expect your flock to learn to evangelize? Or do you plan on doing it all yourself?

The Modern Evangelical

One of my daily stops on the Internet is a blog called The Recliner Commentaries. Dennis, the blogs author, does a great job of compiling current news items and adding his Christian perspective in the form of commentary. One of today's entries was a post called The Evangelical vote The whole article is well worth reading, but the gist of it was a list of many of the issues that are by and large supported by Democrats, but would not/should not be supported by a Christian. Dennis ends with the statement that he is "at a loss to understand how Evangelical Christians can vote Democrat with a clear conscience." This is my answer to that statement.

I think the explanation of how Evangelical Christians can vote Democrat is obvious. The term "Evangelical" itself has gone the same way as the term "Christian". Early on in New Testament times, the term Christian meant only one thing. A born again follower of Jesus Christ. Today I think we would be extremely generous in estimating that 20% of those calling themselves Christian would match that first century definition.

Even so, the term "Evangelical Christian." Unless I am mistaken, the term Evangelical came into popular use during the last century to differentiate those who were serious Christians from those who were not. Calling yourself a Christian had lost its meaning from overuse by those who were only nominally Christian, or in my view not really Christians at all. In fact, I would submit that those who claim to be Christians, but have never been born again, are guilty of breaking the command in Exodus 20:7 "Thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain." I hold to the view that the purest meaning of this command has to do with calling yourself a Christian , and yet the taking of that name to yourself having no effect.

This is nothing new. Even as Paul explains in the book of Romans, not all of national Israel were God's elect. Romans 9:6 says in part "....For they are not all Israel, which are of Israel:" I don't believe we are misusing the words by applying it thus: For they are not all Christians, which are of Christianity, or they are not all Evangelicals, which are of Evangelicalism.

So if the question is how to understand how Evangelical Christians can vote Democrat with a clear conscience, my answer is that "they are not all Israel, which are of Israel."

The Silver Lining to High Gas Prices

The high price of gas has brought with is one silver lining this summer. It has gotten me out of my pickup and back onto the Knucklehead. To my shame, over the past several years, I had just gotten out of the habit of riding to work. Seemed as though there was always some reason not to ride, whether it was wet weather, too much "stuff" that needed to go with, or something.

But, this year was different. Spurred on by high gas prices, I doubt there have been a dozen days this summer that I did not ride to work. And most days I had a passenger with me. You see about 2 years back my wife Jane worked out a deal with our daughter Megan. Since Jane had a hankering for a puppy, and Megan's kids (our grandchildren) did too, they decided we should get one and have "joint custody". It seemed reasonable. Their house was only a few blocks away, and since Megan was home during the daytime, the dog would stay with them during the week, and with Jane and I weekends.

That went pretty well for a while; until Megan and her husband bought a brand new house about 20 miles away. Really, who wants a dog messing up a brand new house? So the "joint custody" morphed into Grandma and Gramps having a full time dog (who goes by the name "Lady"). And since my wife works in an office, guess who brings Lady to work with him every day.

Enter a cheap sidecar from a swapmeet. I never cared much for sidecars, but I did like to at least have the option of riding to work. And besides, who can resist a dog in a sidecar.

Incidentally, if you are considering a sidecar, I highly recommend one of these light weight aftermarket units rather than the overweight H.D. hacks. The OEM sidecars (in my experience) "pull" one direction when accelerating and the other when braking, not to mention hurting acceleration considerably. This 1973 vintage sidecar, weighing in at only 175 pounds does none of these things.

New Vespa museum in Ravenna

VespaThe new Vespa museum, called ‘Collezione Vespa Mauro Pascoli” was opened last Saturday in Ravenna, at the Mir di Fornace Zarattini, in the presence of 12,000 people.
Dedicated to the legendary scooter, the museum extends across more than 500 square metres and is part of the “Terra di Motori” group of 12 museums that includes historic bikes and cars. Of the attendance numbers, about 1000 people came from overseas for the opening.
The museum holds more than 150 exhibits of Vespa, Ape and other Piaggio vehicles, 1,500 images of posters, gatherings, photos and brochures and about 200 manuals. The exhibition comes from a private collection of a dealer in parts for vintage Vespas and includes plaques, trophies, catalogues of parts changes, service station manuals, toy models and accessories dating from 1946.
Pontadera, Italy
(at the Piaggio factory)

Has everyone heard of Scooterworks, in Chicago? They have been around forever. There is another Scooterworks, in London, as well. There is no connection between the two except that they share the same passion for getting Vespas back on the road.

In anticipation of our upcoming vacation to Scotland and England, I jumped on the Internet to contact anyone I could find there who had anything to do with scooters. Not much luck. A place called Scooterworks UK had a nice web site and the owner wrote back inviting me to visit his shop when I arrived.

The Vespa Museum
At the Piaggio Factory
Pontedera, Italy

By Alan Dollar

Most scooter enthusiasts know the story of Piaggio developing the Vespa after World War II as a means of affordable transportation to aid in the re-construction of war torn Italy. The industrial history of the Piaggio Company actually began sixty years earlier in 1884 when they started making interiors, cabinets and fine woodwork for luxury liners and other sailing ships.

Twenty years later the building of the Italian railroad was becoming a booming industry. The Piaggio Company diversified from woodworking to metal work. In 1908, they started producing a variety of railway cars and streetcars. Detailed, of course, with the same luxury interiors they had designed and produced for ships.

In 1924, they branched out even further, adding an aeronautical division to their company. It was located in Pontedera. To aid the efforts of World War I they produced entire aircraft including engines.

It was during that time that Enrico Piaggio and aeronautical engineer Corradino D’Ascanio, the two men who would later be responsible for developing the Vespa motor scooter, joined the company. Piaggio was in the forefront of airplane and engine development with many technical achievements to their credit. Did you know that D’Ascanio, that the man who designed the first Vespa, designed the first successful hovering helicopter in 1930?

Such innovations ended during WW II when the Pontedera factory was demolished by allied bombing. Recovery from this devastation was the driving force that led to the invention of the Vespa!

The first prototype MP5 (Moto Piaggio 5), developed in 1945, became known as the Paperino (Donald Duck). The design did not pass muster with Enrico Piaggio. He directed D”Ascanio to design a innovative vehicle for transportation based on aeronautical concepts. The resulting MP6 was labeled by Enrico as the Vespa because it looked to him like a wasp (vespa in Italian).

The aerodynamics and monocoque (integrated) body were straight from airplane design. The front suspension was designed after the trailing link rear wheel of an airplane’s landing gear. The wheels were mounted on one side of the fork and engine to make it easier to change flat tires. The gears where shifted by twisting the grip where the clutch was located. All of these design innovations were firsts in the field of two-wheel transportation.

That design led to a new direction for the Piaggio Company in 1946, and to the mass production Vespa scooters. It is a design and mechanical icon that has captured the imagination of people around the world for fifty-seven years!

A number of enlightening books have been published in the last few years that include nice pictorial displays of the entire model line of Vespa. After reading all the books and studying all the photos, I, like many others, wanted to see the real thing, in Italy. So, Tony Garbarino and I cashed in our frequent flyer miles for a free flight to the homeland of Vespa, where we set off for a week to see nothing but scooter stuff!

The plan was to see the Piaggio Vespa Museum, some private collections, parts suppliers and finish with the annual swap meet at Novergro. Tony, who knows Italy well, navigated us through his preplanned course like a seasoned rider through a Gymkhana. We did it all in a whirlwind, 8 days, 7 cities, and 6 hotels.

We took one side trip from our scooter path in Pizza, to visit the only cultural site we would see while in Italy. The magnificent leaning tower had just reopened to the public after twelve years of construction to stabilize its tilt. It was a magnificent experience to stand on top of such a historic and beautiful structure. At the same time that I was in awe of my surroundings my mind kept saying, today we see Pontedera. I must be obsessed.

At mid-day we found the sprawling Piaggio factory in Pontedera. The factory complex is larger than I imagined with rows of large concrete buildings, projecting the same appearance as pre war photos. The museum itself fills a small part of one building yet the display seems enormous.

Rolf Soltou, former Piaggio representative to America, told me he was at the factory for a week of training later that month. He was shown almost all aspects of the grand facility. (Wouldn’t it be great to read an article about that experience?)

The first scooters one sees upon arriving are the ones parked in front, ridden to work by the employees. On display outside the scooter museum are a commuter train and airplane, built by Piaggio before WWII.

When we first arrived a chap in Piaggio overalls was outside preparing a newly acquired Vespa for the museum display. The original red Pentaro had been in service as a fire engine! Later during our visit, he drove the Pentaro fire truck into position in the display, complete with original axe, fire hose and siren. I spontaneously gave him and the Pentaro a rousing applause. He seemed pleased by that and motioned at us to follow him into the back room for more unique displays.

The half-day we spent there flew by as if it were minutes. After leaving a lot of money at the museum store and receiving an armload of free goodies and posters, we were ready to embark on the next phase of our journey.

As we walked to the entrance, a side door burst open and the jovial mechanic came out. He stuffed another handful of goodies into my bag and shook my hand. We had made another scooter friend, as so often happens when people who love Vespas meet!


Preach the Word!

"Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine." 2 Timothy 4:2

I absolutely love good preaching! Good, strong, authoritative preaching. And of course to be authoritative, that preaching can be only be of one type; Biblical. If the preaching is not from the Bible, then in my opinion it lacks any authority.

At the very end of what we call the Sermon on the Mount we see something about this authority:

Matthew 7:28,29 "And it came to pass, when Jesus had ended these sayings, the people were astonished at his doctrine: For he taught them as one having authority, and not as the scribes."

Note a couple thing here. Teaching is a part and parcel of preaching, unless we have mislabeled the "Sermon" on the Mount. Jesus taught as one having authority. That is because of who he is. The book of John says that Jesus is the Word. And the Word is God! Jesus preached and taught with authority because he is God. But how can a mere man preach with authority? It's easy if you preach the Bible. The authority comes from the Word of God, not from the eloquence or style of the preacher (if it was the latter I, for one, would never dare set foot behind a pulpit).

Also note that preaching and teaching involves doctrine. That word doctrine isn't one that should scare you away. It simply means a principle or the body of principles in a branch of knowledge or system of belief . That definition comes from Websters. In the case of true Christianity, that would be a principle in a branch of knowledge. The knowledge of the one true God, Yahweh. In the case of all other religions, doctrine would be merely a principle in a system of belief.

If you go back to the very beginning of the sermon on the mount (Matthew 5:1) , you will find that Jesus sat down to teach/preach this message. So why is it customary for a preacher of our day to stand behind a pulpit to teach? If you go to Luke chapter 4, I believe I can give you an answer.

It has been said that it was customary in the Jewish culture of that day that a teacher would sit down to teach. This would seem to be verified by the account of the Sermon on the Mount, as well as here in Luke 4. Beginning in Luke 4:16-17 we see that the Bible says: "And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read. And there was delivered unto him the book of the prophet Esaias. And when he had opened the book, he found the place where it was written, .... "

After reading the passage from Isaiah, we find this in verses 20 and 21: "And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him. And he began to say unto them, This day is this scripture fulfilled in your ears."

Jesus stood up to read from the scriptures. Then he sat down and taught with authority. Now if Jesus stood up to read God's word, would it not be reasonable to emulate him? And since any authority in our preaching/teaching comes directly from God's word, perhaps it is best that we remain standing to remind us to to keep the focus of our preaching on the Bible.

Yes, I do love good preaching. Strong and authoritative. But you know what? The meekest and mildest of preachers can preach in a strong, authoritative way even with a meek and mild delivery. The strength and authority comes from the Word not the preacher!
