clutch brake????

As Old Man mentioned the trans would need removed if it is a 1 piece like this one. A 2 piece can be changed with the tran bolted in place.

 

The trans does not have to come out. Just had one replaced and they cut it off. This was on a 2012 Mack.

 

I've cut several one piece ones out,can be a pita but it can be done.Lot easier than pulling the trans.My son has an air tool just for doing it,like a wizzer wheel on an extension.

 

You can cut a 1 piece out with a torch (make sure you're pretty good with a torch first) and replace with a 2 piece. It might just need grease though. If I don't keep lots of grease in my release bearing, or if I use summer grease in the winter, it doesn't slide right and the clutch brake doesn't work properly.

 

If the clutch is set up properly the clutch break should in away be adjusted when the clutch is adjusted. The clutch brake squeeze is set initially by lengthening or shortening the clutch linkage. ( Not something that needs done very often and you want to know what your doing) Once the clutch break is set then the clutch will have to be adjusted to give free play. As the clutch disk wears the release brg will move slightly closer to the release fork which takes your free play away. Also when the release brg moves toward the fork it also moves away from the clutch break causeing less clutch break squeeze which causes your grinding when trying to get in gear. When the clutch is adjusted again the release brg actually gets moved away from the fork ( gaining freeplay) and closes the gap between release brg and the clutch break (increasing squeeze).

This is what happens in a perfect world but it can also be effected by driving style. Basically as long as the techs know what they are doing it is possibly a adjustment issue or the break is worn out. One piece as stated above can be removed with torch, air chisel, or some techs have built a tool by grinding a deep groove in a 3/4 extension. Put clutch brake in the groove and hit the trigger on the 3/4 impact and it will shear apart.

Either way it should not be a big issue to correct if the have to adjust linkage more time will be required as the linkage ends that are adjustable will likely be seized up.

 

Yes they cot the one piece out with a torch that is what takes the longest amount of time in replacing one .the tranny doesn't have to be removed

 

I like that idea with cutting a deep groove in a 3/4 extension.I may try it.I have cut out many with a torch but be sure and wear a welders jacket and facemask and be ready to move quickly!!Hot grease and molten steel does wonders for thinning out your Chest Hair

 

Oh and 9 times out of ten the keyway (or bolts on an eaton clutch brake) sheers off .Its rare that i see one that is actually worn out.

 

Overgreasing the throw out bearing,can ruin a clutch brake,too.
