"High pedal" or worn clutch?

[quikshft]

I've noticed that my clutch seems to be engaging near the end of the 'stroke' of the pedal. Is this a sign that it's nearing the end of it's usefull life, or is there just something I'm going to have to adjust to get it to operate in a more normal manner?

Thanks, Jeff

Hi Jeff, I just looked through my manual for my 91 and according to it the hydraulic clutch assembly is put together as a unit and not a servicable item. Could not find any thing on ajustment. Bill

Jeff I don't have a manual to look at but I looked at my truck and from other experience I would suggest a couple of things. First be certain the reservoir is full. In 410k miles, mine has not required fluid but I understand that they will sometimes need fluid added. If you are needing fluid, that will be a problem to address with most likely new parts. They seldom "fix" themselves and stop leaking. If the level is low, you have most likely ingested air into the system and will have to purge the system after filling the reservoir. It is self purging to some extent with exercising the clutch. It can be a booger.



If the fluid level is ok then look a the rod going into the clutch master cylinder. This requires a light and a bit of contortioning to see under the dash and determine that all is well under there. I have seen a post on things coming apart with the pedal parts and pedal mount.



If all that is working as it should, get a friend to watch the clutch slave cylinder as you press the pedal. The slave should be moving as you press the pedal. The system is made such that the throwout is in contact with the clutch fingers all the time. Any movement on the slave should be disengaging the clutch. If all the above is working as it should, you can expect that you do indeed have a clutch problem. My experience with the Sachs clutch is that it is not the problem. But everything wears out eventually. So you can't rule out any thing.



Do not have the engine running while anyone is under the truck.

OOps. I think I went off in the wrong direction. You are saying that the pedal is high. All my experience suggests a worn clutch.

Yes, engagement doesn't happen until the pedal is close to it's full release. My experience says worn clutch as well, but I'm just attempting to get some other opinions before I might decide to tear into it.

clutch

Well I have seen the inside of mine four times and I can tell you that there is a good deal of travel available on the throwout sleeve. As long as the clutch isn't slipping, I would not pull it down. It will be necessary if it starts to slip. You would have to be the judge of that in relation to how you drive. The disk could be replaced for a relatively low price without the pressure plate if the pressure plate isn't warped. Be sure to change the throwout bearing and pilot bearing when you are into the job.



The flywheel can be warped also.



Good luck however it goes.
