Recently when I came to a light, I noticed my clutch was grabbing, even with the pedal to the floor.
Assuming it was the master cylinder I replaced it... Somehow it is slightly better, but still dragging.
The clutch never slips.
Could it be that my clutch material has come apart a bit, maybe a rivet failing?
Something else?
I have never had a clutch brake on the truck, it was worn out before I got it, could this maybe be in there falling apart? My local small truck shop said it looks wet inside the inspection plate?
How many hours it is to replace the clutch disc?

It’s new clutch time. Dampening springs break or come dislodged and cause the clutch to drag. Can be intermittent in the beginning.
Replacement times vary, but average shop time for clutch replacement is around 8-12 hours when done correctly.Rideandrepair and Diesel Dave Thank this. -
Sounds like another self adjusting clutch headache.
Rideandrepair Thanks this. -
@Goodysnap , what the life on those self adjusting clutches?

So there are options besides the paccar clutch?

Paccar doesn’t make the clutch. Get genuine Eaton. But you can get a solo or manual adjust.
You will have to keep tabs on the adjustment with a manual on your 579. Can’t feel the free play with the hydraulic clutch. They did come with both from the factory as options.Oxbow and Diesel Dave Thank this. -

The clutches are all similar as in 2” - 10 spline double disc pull type. There are wide range of torque and part numbers for engine torque and trans application. Best to look up and cross from OE or look up from the part number off old clutch to match.Any good parts house should be able to cross solo to manual numbers for the same clutch.
Oxbow, Diesel Dave and scoobertdoo Thank this.
