Archived 6-speed clutch won't disengage

[TBrown]

The truck is a 2001 HO. six speed. The problem is that the clutch won't disengage to shift. If you start it in gear it will pull ahead, acts like an auto that is in drive, have to hold the brake. Never made any noise. You can speed shift it but down shifting is impossible. Problem came on fairly quickly with no other problems. Is this the clutch or are there problems with the master or slave that is causing this? Anyone know where the slave cylinder is, inside or on top of the bellhousing? Any help would be great,

Tony

Tony, the slave cylender is on the drivers side of the bell housing, I would suspect your problem to be here, first check your fluid level in the master and then bleed it to the slave and see if that helps... ... ... ... ... ... ... ... ... Kevin

Does the pedal have some extra "slop" in it? You might check that the master is tightly mounted. Good luck with it.

The truck isn't mine, but as far as I was told the clutch feels normal in the pedal. The fluid level is right at the top and there are no leaks. I have been thinking that maybe the pressure plate is failing and some of the fingers are broken and not releasing. Has anyone seen that happen? Thanks, Tony

The owner of the trucks name is Justin, and I showed him the site and he is signing up, he would really appreciate your help, thanks again.

Not being able to disengage could also be caused by a seized pilot bearing. This would, in effect, lock the trans. input shaft to the flywheel.



This would also make the clutch pedal feel like it normally does because it really is actuating the clutch - it's just not allowing the transmission shaft to freewheel in relation to the flywheel.

I had the exactly the same problem... it was the pilot bearing.

Another point to ponder is the Hydraulic Master and Slave cylinders. Mine went out and th clutch pedal only lost a *little* pressure,, it still felt like it was disengaging, I had no fluid leaks, and the fluid was topped of. My leak was completely internal.



The Hyadraulic cylinders come in one complete piece from Dodge, filled with fluid, primed and completely ready to install,, last I checked there were no aftermarket options available.



My thoughts,

Sounds like a pilot bearing to me also.

If it is the pilot bearing, then what is the fix? Using the kevlar bushing like on a five speed? How much damage does it do to the input shaft? If the kevlar bushing is the fix, is it the same as a five speed bushing? I have a kevlar bushing for a five speed from when I put in my South Bend Clutch. There isn't anyway to tell if it is the hydralic system is there? Seems it would be hard to tell if it is moving the full travel or not. Thanks for your help.

I don't know about these beasts but I've seen car specs for clearance between the disk and the pressure plate or flywheel of a few thousandths with the clutch pedal pushed in fully.

best to bite the bullet and get a south bend clutch. if that clutch is not slipping, it will soon. especially with power mods.



Edit, oops, I just saw you have a SB cluch, well I have the SB con OFE and it so far is doing great.

One more thing -- I've seen clutch discs adhere to the flywheel and/or pressure plate after going through deep water (albeit saltwater) and sitting overnight.

Clutch Hub rivets

My wife came up to an intersection a couple of years ago and the clutch would'nt disengage. Could have been bad, but she had the forthought to turn it off. She started it in gear and shifted it without the clutch to get home. I scratched my brain and asked alot of questions checked my master and slave cylinders to no avail. I removed the trany and found that the friction disk hub was loosening up and a rivet had lodged itself between the disk and the pressure plate. I reinstalled a OEM setup from Napa but knowing what I do know I would probably go with a heavier duty aftermarket unit. My 94 must have a heavier clutch in it because its alot harder to push in than the 95.

Shoulda been there.

We had done our KDP fix at my place this weekend. There was enough brain power there that we were well on our way to solving the worlds problems in my driveway. I'm sure we could squeezed in a clutch discussion and some troubleshooting. If you want to, let me know if you want to swing by my place and I will see if I can get a boroscope from work and we can try to take a look at it.



All of the above is good information and things to check on. I am thinking cover plate or hub problems. Get back to me if you want my help. (Although, you must be pretty desperate to want that)
