Topic: 50 clutch adjustment


Cherokee    -- 10-01-2009 @ 4:28 PM
  Recently I installed a new clutch with a newly turned flywheel. The clutch/pressure plate and flywheel were tuned in by them. When I installed, I could not get in gear w/out grinding. I called them and they said that unfortunately, a new man had done set-up and they apologized for not checking it before giving to me. This tranny has an inspection window, so I'm able to
adjust the pressure plate fingers with the adjustment bolts. I'm aware that I need to measure all 3 locations and make certain of same distance off flywheel, but can you give me any additional advice to guide me. I have done some adjusting on it and my linkage, but I don't seem to be making much progress. Perhaps it's not a good idea to attempt this through the inspection window and I should just go ahead and pull it out and take it back to them for another set-up. I'm also beginning to wonder if maybe my trans synchronizers are worn out. Thanks for any advice you might give me.

  Cherokee, I haven't done the job you are trying, but although it sounds
like it can be done, I'd opt to bite the bullet and pull the tranny. Usually
the apparent shortcut is the long way around!

  The adjustment to the fingers is a precision adjustment best left to the experts. If you are sure that the clevis to the clutch pedal is adjusted correctly, pull the clutch and have the folks that rebuilt it adjust it properly, or, if they don't know how, find another shop that can.

By-the-way, the flywheel should be "ground," not "turned."

  You cannot successfully adjust the pressure plate fingers with the assembly in the vehicle. It requires a special jig, as the tolerance is measured in the thousandths. If you attempt to do it, it is more than likely that you will have to replace the pressure plate. Unless the linkage has been changed or not properly adjusted, the clutch assembly has been incorrectly installed, or damaged in the process.

  Thanks for the good advice! I had already resigned myself to the task of pulling everything again....oh well, guess I'll never get to old to no longer need the practice. I've also decided that I'll never get old enough to reside outside the jurisdiction of "Murphy's Law"!

  Don't feel bad. For most of us, the first time we do a new job, we get it wrong. The second time it is OK, but now we believe we can get it better. The third time it is the way we expected it to be. The catch is that by the next time we have to repeat the job, we have to re-learn it, anyway, at least for us in the "golden years".

  hi
one thing I would like to mention is that when installing the new clutch,. it that when you are tightening the clutch pressure plate , is to tighten it little by little and keep turning the engine over or work your way around the pressure plate so you draw up the bolts evenly, other wise you could ruin the new clutch job,by warping the clutch pressure plate, also make sure it seats correctly on the flywheel,
hope this helps 37RAGTOPMAN

  Something jumped out at me and I wondered about a possibility that comes up here and there. You mentioned that the trans had an inspection window where you could see the clutch fingers. That suggests that you have a pickup truck 3 speed trans with the bell housing cast as part of the gearbox.

If for some reason you have a 9.5" diameter clutch, the truck trans (and large input shaft + large throw out bearing) would not mate properly to the pressure plate fingers of a Ford 9.5" clutch plate.

I am often asked about clutch/trans problems and come to find out that the application turned out to be a mixed bag of car/truck components or something else that gave a clue to the problem. Can you elaborate with more details about the engine, the trans, the clutch involved, etc?

  it sounds to me like you have installed the clutch disc backwards. I did this on my very first clutch job. the splined hub is hitting the flywheel around the center and not allowing the clutch to release. the 3 fingers should never need adjusting especially on a fresh pressure plate.
