2002 Ram 2500 w/ 6-speed
My clutch does not disengage all of a sudden. There were no warning signs. The clutch pedal does not feel any different than usual. I cannot see any evidence of leakage anywhere from the master or slave cylinder. The fluid level is fine. The slave cylinder at the tranny housing is secure. The only recent changes I have made were to change my oil and oil filter, changed air filter, and added some power steering fluid.
I have had to replace the slave cylinder some years ago in this truck, but I can't recall whether the symptoms were just the same. I am reading over my manual some more to try and get ideas on what to test, but if anyone has any advice to toss my way, I'd be much appreciated. Thanks for reading my post!
Can you get it outta gear once in gear and moving? When my slave cylinder went it did just that. Had to start it in 3rd and crawl home. Few years later it started doing the same thing. figured out that throw out bearing was seized to the input shaft.
Well, I just noticed it give me very slight trouble taking it out of gear as I was about to park, and I worried for just a sec, but then it worked again fine when I shifted in gear for the last time before stopping. It could just be that RPMs were matched up though. Anyway, when I got back and tried putting it in any gear with clutch fully depressed, it would not go at all, would grind in reverse, and try to lurch a little bit going into first. I didn't force it. Traffic was horrendous and there's no way I'd try to limp it home at that time.
Is there any good way to test the slave cylinder? Can I just take it out and pump the clutch, or does it require some kind of stop to keep the ram from blowing out?
I just got done replacing the master and slave cylinder assembly. Got it new for $229 from the dealer, installed with no apparent problems, and the truck does exactly the same thing, cannot disengage clutch.
I checked the feel of the clutch release lever before installing the new slave cylinder in the clutch housing, and it feels fine, with very little play.
Also, I'm pretty sure that there was never a problem with the master or slave cylinders, because before removing the slave completely, I just backed it out a bit and verified that it was putting pressure on the clutch release lever by having my friend press down just a little on it. However, after taking the slave all the way out, the ram will no longer go back in at all, and from what a service tech at the dealership said, even if I could get it back in, it would still end up leaking.
It's really upsetting to me that the service manual didn't mention any considerations for keeping the slave cylinder compressed when removing it to avoid ruining it. I guess I have learned a lesson about trusting the manual.
So, it looks like I will have to just take it to a shop, which I really do not want to do, but I have no other options at this point. According to the diagnosis chart in the manual (FWIW), it looks like either the clutch disc is damaged, or the release fork is damaged. My guess would be the clutch itself.
I'll start shopping for clutch prices. Thanks for the assistance, guys.
I am having the exact same problem. Even went as far as replacing both master and slave cylinders for the clutch which I have done once before on this truck 2 years ago. Bled them out about 10 times with no air coming out and still the same problem... I am leaning towards worn pivot ball for the clutch fork, the clutch fork itself or a worn out pressure plate (bent/broken diaphragms?)
The pilot bearing was totally chewed up and had fallen apart. None of the rollers were still in there. The clutch also was in need of replacing, so that was done too. It tore up the input shaft a bit, but the mechanic felt good about how he was able to smooth it out, though it did leave a noticeable lull. I figured I might as well have them try that; if it tears up the pilot bearing due to too much of a gap, then I'm just back to square 1 for the most part. I'll get a new input shaft at that point if it comes to that, but it's around $1100 I think, so I decided to take my chances for now.
Best of luck to you! Hopefully it's as simple as my issue and you don't need anything else replaced.
