Is there a best way to remove the pin camshaft from the clutch arm? I am having trouble disengaging the clutch and I am sure that the problem is that the clutch arm hits on the bicycle frame. I am sure if I take it back a few noches off the clutch arm, it will solve the problem. The clutch did work, but now it does not.
 
Oh no not another clutch thread! ;)

It did work but now it takes a really long pull to open/disengage? Sounds like you took the sprocket cover off and lost the ball bearing that is meant sit under the bucking bar.

With the ball bearing NOT lost on the workshop floor it is actually more common to adjust the lever in the OPPOSITE direction (CCW) to make it a bit easier to pull.
 
thougth about that, but the bucking bar sticks out about a quarter inch. I think its enough, but I will have to double check. The clutch arm still hits on the frame, and its bothersome.

No, that's fine, 6mm (~1/4") is the size of the ball bearing. I don't know what else could suddenly change though.. Check the flower nut retaining screw is in place so the flower nut can't come out of adjustment.. That's all I can think of.
 
The bearing looks to be in there so, i just have to take off the clutch arm from the pin cam and move it a few notches.

Yea, I see alot of these threads latley. Sorry to put up another one. I still think its in the clutch arm and having it rub up on the frame.

I will check the flower nut tommorow
 
No problem. I like the puzzle in a way.
I just don't see how it worked before and then stopped working if it has anything to do with the position of the lever on the cam, which hasn't changed.

I would have moved mine (the opposite way) to make the cable pull more like 90° to the arm, in order to make it less of a heavy pull, but when I tried to I couldn't get the lever off the splined cam shaft.. I think the manufacturers hammered it on there.
 
yea thats what I am trying to do, to remove the camshaft off the spline. It is becoming a major PITA. I am hoping someone here can shead some wisdom on it. I just have to think that its the problem, because it does rub on the frame. It did rub on the frame before, but it did work, not without some effort. Last time it was running, I did notice that is was becomming more difficult to use the clutch.
 
Most stuck bike parts (pedals seized into crank arms) I put in the oven to unseize them. I suppose there would be no harm in trying that method, although it isn't seized by corrosion as far as I can tell. I haven't read anything about this (or the root) problem though as far as I can recall.
 
properly adjusted, that arm should pointing just about straight backwards when released, if your isn't, you need adjustment rather than a rotated arm - if you do rotate the arm, you'll have much less cam action at the bottom of the arm where it pushes the bucking bar
 
I just took off the other side today and the clutch appears to be working fine. Its not sticking. So the problems has to be the clutch arm hitting the frame. Just wish there was an easy way of taking the clutch arm from the pin camshaft.

I also noticed that there was some wear on the pin camshaft and that also would be the reason for additional clutch disengagement.

Ideas still welcome.
