G56 clutch problems.

G56 clutch problems. - 02/07/14 09:12 PM

07 2500 5.9l 69K miles G56 clutch will not disengage.
mash the pedal, can not put it in gear. Acts as if you were not pushing the pedal in far enough.
No noise from the throwout brg etc...
Last couple of days, clutch would not engage or disengage until the pedal was almost all the way up/out.
Do I risk a $100+ on a new hydraulic setup and hope that is the problem? Or go ahead and order a complete Southbend Clutch kit?
No evidence of leaks, fluid level was ok but dirty.
No slpiiage.

Any advice before I spend money that I do not have?
Thanks in advance.
Troy

Id spend some time diagnosing it before spending any money.. Id suspect a bad slave cyl..

Same here. Why spend money on the hydraulics and then find out your disc/pressure plate is what's broke?

Thanks guys

I agree about not spending $, not sure how much more I can diagnose without dropping the trans(which I can't do in my driveway like a torqueflite). I want to pull the slave and check it's action when the pedal is pushed, but from what I have read, doing what I said would cause it to over extend and get air in the line.

The South Bend clutch I had done in my 07 G56 was junk from the beginning, I even took it to their shop in Indiana and they said that is the way it should sound and work!

After another 500 miles I took that junk out and put in another aftermarket clutch with the same flywheel and it was fine.

My 2002 had a SB clutch installed by the PO, it was great! I had a clutch slave failure, too.

You can get one here

or it may be cheaper to go OEM

Do your homework

You should be able to pull the slave cylinder off the bell and step on the pedal to watch it move. The rod should move out about 3/4". If its moving out, the pressure plate or throw out bearing has an issue. The last 3 clutches I've replaced had pressure plate and/or throw out bearing issues, and all of them quit disengaging. Usually the hydraulic part of the clutch system either works or it doesn't, not much can partly fail.

Two nuts and a pedal push will tell the story. Gene

careful doing that...the slave on my Dakota seems to have a spring in it that keeps it extended snug up against the fork. must be to keep it engaged with the fork so it doesn't fall off? when not installed and hanging free, it would fully extend by itself, and then if you stroke the clutch pedal, it would push the cup and pushrod out the end of the slave.

correct. same with mine, the 2 plastic lock ties hold the rod/piston compressed in the cyl.

you un-hook the ties and let the spring push the piston out to the end off bore to open the hydro line or bleed system. you push the rod back in a couple strokes to remove air then re-hook lock ties and install back into fork/bell,

I just changed the clutch in my sons 94 ram, the disc eat into the flywheel and gave a no clutch issue.

the disc groove in the flywheel was 3/4 the thickness of the disc itself so the PP could not hold the disc from slipping, pedel at the top of stroke to release...till it would not move at all for the no clutch problem.

surprised to see disc/PP still in a burnt but fair shape looking but flywheel with a deep groove worn in it.

I am thinking the clutch was replaced on a burnt/worn flywheel and then it just killed it in the short time my son drove it.

sucks to have the rod drop in the bell, you have to remove bell from engine to remove rod...the very reason for the plastic lock ties.

I have seen the plastic tip on the rod broken and the metal rod wear a hole thru the fork cup also for no worky clutch.

yep, you do not want to remove the slave and then push the clutch pedal. the self adjusting spring in the slave will push the pushrod all the way out and the pedal pressure will pop it out of the bore. Now, I can hold the Prod all the way in and the pedal will not move it.

guess it is all going to come apart now. just wish I could do it with a cardboard creeper and a floor jack.

I have way too much invested in the RB size motors to switch. Thanks anyway.

Not sure if I am understanding things right here, but if you are saying the slave isn't stroking, maybe the master is bypassing, internal leak?

What does the inside of the firewall look like?

I had a '93 Jeep Wrangler, same symptoms (I think) clutch master was leaking at the firewall, and not releasing the clutch.

Yes, I would sell it. Never put any effort into trying to sell it though. If I sold it, it would be a pkg deal. that would be the truck and all of my Mopar stuff(not a lot, few rears,blocks...).

there was no evidence of leakage, pulled the slave and yes it stroked, once. Lost pedal, then I messed the hose up while shoving the rod back into the slave cyl causing it to leak at the angled fitting on the hose end of the slave.

I found these ftting when researching info for my NV4500 swap.

if yours has the roll pin/o-ring 90* fitting or a straight fitting, you can use the russel clutch/brake line fitting for dodge/jeep to run a -3AN/-4AN line.

I was looking to replace the plastic line for mine. you only can get a stock factory pre-bent plastic line when buying a complete hydro clutch system that comes pre-bled and ready to use.

I got my hydro MC/slave cyl from parts geek.com they have them for newer truck also that have the clutch/N-safty switch on the MC.

Those fittings are great! Knock out the roll pins at master and slave, remove line, add these, then use braided steel AN hose.

That's how I adapted the ram SRT-10 Hyd to bearing to my factory master to install the T56 in my Dakota.

Fits together like the factory designed it that way!

Hi RedRam! Long time no yadda yadda. What was the temperature when all this began?

Hey Red, Congrats on the sale.
Been a while since it was above freezing, I'd say from the teens to low 30s.
My clutch problem is either the throw out brg or pressure plate. Tried a different m/c-slave setup today, no joy.
Trans has to be pulled. I will be ordering a new solid flywheel & clutch kit tomorrow.

Thanks! Just wondering since the extreme cold seemed to play havoc with everything at work including hydraulics that may have moisture trapped in the lines.

Finally back on the road. Pressure plate died. Throwout brg was ok, clutch plate and flywheel looked great. Bought a heavy duty single disc Southbend setup that has a lot more clamp than the stock setup did. Engagement is smooth, pedal effort is definitely higher than stock, but I will get used to it. Entire clutch kit was little over $1200 and install was $457 at my local dealer.

Getting away from the stock dual mass setup, I was concerned about trans/gear noise that some after market clutch users report. Only thing I noticed during my 25 mile ride home was when/if you lugged the motor below 1000rpm, you can definitely hear the gear rattle in the trans. Hope to get more than 69k miles out of this one.
No complaints with my dealer's service dept, was expecting more than a $457 bill, and they seemed to have no problem installing non-chrysler parts that I brought to them.

Good luck, let us know when the gear rattle goes away and it is time for a new trans...

Will do

BTW, exactly which Southbend model did you have so much trouble with? And, who's clutch disc solved all of your trans problems?

Re: G56 clutch problems. - 02/27/14 05:21 PM

I don't have the info anymore, the truck did not belong to me. I will never have my trans problems solved, it obviously has to be me...
