06 CTD hyd. clutch

[nibroc]

could not get shifter outa 1st gear or any other gear incl. neutral and pedal is harder to operate---any help? Less than 20K mi. on truck--bought it new

Sounds like new hydraulics are needed.

We put South Bend Clutch upgraded hydraulics in dads 06 when the DMF failed.

It is unfortunate that the truck has only 20,000 miles on it and you are having clutch problems. The factory clutch has two things against it right from the start - the dual mass flywheel that will fail gradually (vibrations) and the automatic clutch adjustment feature that will also fail (slipping).

I realize that these are not your symptoms, but if you are intending on keeping the truck for a long time, a clutch conversion to a single mass flywheel may be in your near future.

As @AH64ID mentions - new hydraulics may be needed. Your symptoms also match a pilot bearing that may be seizing (low miles, but 15 years old).

Yes, but as you mentioned it's 15 years old... that's too few miles for 15 years of use. Too few miles are often as hard on things as too many miles.

The SAC self adj clutch could be the culprit.
If it has accidentally adjusted to thin disc condition but still has a thick disc. Increased release load.
A pic showing SAC spring condition may confirm.

thanks for the replies--found an indy 1/2 mi. from house--that's what he diagnosed w/o even looking at the truck--said he would order parts today --will look into South Bend upgraded hydraulics
ignorant about DMF and SAC--the indy *****ed about oversized tires on rear and 20K mi. on truck

That's exactly how mine acted when the pilot needle bearing seized.. then it disintegrated. I was going to say it but the low miles,,, guess its still possible

Pilot bearing failure wouldn’t affect pedal effort unless it chunked and came back thru the disc and lodged in SAC somewhere.

Clearly you need another shop. They just explained to you “no warranty on our work “ due to over size tires. Don’t ignore warning signs... Ignorant of DMF and they are ordering parts... For Who? I don’t see you using em.

Correct, mine was just stuck an any gear selected

called south bend and talked to Ryan---told me any autozone has the hyd parts 'bout $200

You have a 2006, those all had the G56 and a SAC/DMF.

This can get confusing but you need to match the hydros to the existing clutch system. The biggy is a SAC needs less stroke at the bearing and a 16mm master cyl bore dia is correct match. 18mm bore is for non-SAC systems.

This is a case where bigger ain’t better.

I have the factory hydraulic setup from my '07 sitting up in my garage from when I installed a South Bend. You are welcome to it if you would want it. I can't guarantee how well it works, but it was fine when I swapped clutches a few years ago. It may take me a few days to box it up and mail it out. But, I'd be willing to if it would help you out.

How would you know all that ?? LOL !!!!

39 years in the clutch aftermarket.

Been there done that. Still capable of learning or screwing up.

My 2005 NV5600 is sitting right behind me at about 220K and I installed a new clutch in it as a retirement present to myself.

 

[nibroc]

update--got a Kentucky Clutch HD kit w/hydraulics installed today---shifts perfect--seems as though truck has been shifting kinda hard for a few years as I recall and did not know the hyds. were the culprit--happy camper

 

[GCroyle]

Air bubble in hydro's really messes things up. The hydraulic system can be easily independently tested for air. But getting the bubble out of this system you must remove the entire hydraulic system and bench burp it. Been there done that and test again to confirm.

But any chance or interest to confirm for the record, OEM DMF/SAC clutch correct? Now how about a link to the exact part number hydraulic system you installed?
