I wanted to blow this past a few of you guys, driving without my floorboards, and testing new external AC brakes, my clutch kinda shudders when I come off the gas and let out the pedal to go into high gear. I am smoothly shifting from low to high by easing off the throttle and the clutch shudders just before it grabs? Once it grabs, it holds well but that first moment is iffy. Does it possibly sound like clutch fingers, clevis is the incorrect length, or maybe or Kevlar bands?
James -- My kevlar bands don't shudder, and none of mine ever have. It must be some other problem. It's difficult to say what the problem might be without driving the car to determine what's going on.
What kind of shape is your brake band inside? Probably a rough surface where the clutch rides.
Jack, I think you mean drum instead of band.
Yes,my bad,but I'm old so forgive me.
I don't believe it can be a band problem as shifting from low to high you are releasing the band and the high clutch is being applied. I have the same issue at the moment but yet to investigate it. Another possible issue maybe the band not fully releasing quickly enough and being bound up for some reason. In that case, you have both the band and clutch applied at the same time. Not a good scenario
Just my thoughts. Alan
Jack, you are not old, just experienced like me and Mikey.
It feels to me like the clutch doesn't grab right away- I am tempted to turn the clutch fingers in a 1/2 turn and see if that alleviates the shudder.
Is the clutch that's making racket or the engine?
Have you tried retarding the spark when you go into high until you pick up speed?
James; Have you recently changed your oil and put in one of the modern oils with friction reducers? This will cause a shudder going into high and may also cause a shudder just before stopping. Try changing the oil with a straight 30 weight if possible if not then try getting motorcycle oil for motorcycles with internal transmissions this should cure the problem if it is oil related.
The shudder is from the pedal being released too slowly. Try releasing faster as the rpms of the engine are coming down.
A couple of things:
1. When you release the clutch pedal to high push the throttle ALL the way up when in neutral and pause very briefly in neutral until the engine is slowed down. Then release into high and give it some gas AFTER the pedal is all the way back.
2. Be sure the parking brake rods are all the way back without bending when the lever is all the way forward. You can check for this by removing the clevis pins from the front ends of the rods and pushing the lever all the way forward. If you have to force the rods backward to get the pins back in, the rods are too long and should be adjusted shorter so that the pins will just go in without forcing. If one side pulls before the other stops, tighten the rod on the loose side half a turn at a time until you get them to stop evenly.
Thanks, will do.
