I'm working on a D7 3t that clutch brake seems not working. I am not at the tractor till week of 26 Aug. 2024.Im looking at parts book and see the assembly. What i need to know from the experienced hands is it the lining on the shoe in most cases? I'm Shure adjustment is needed. I'm trying to see what parts can be found and maybe purchased ahead of time. I failed to inspect before i left the machine a few weeks ago. Thanks for the vast knowledge on this page!

The ACMOC library contains all of manuals for the D7 3T. The operations and maintenance instructions(OMI) has the clutch, transmission brake instructions and more. I have a OMI for sale cheap if you are interested send me a PM.

Thank you, I have all the publications . My question was directed to a hand ‘si on persons comments on actually doing the repairs

Have not done any work on a D7, so a wild question. But I know Cat used many of the same type pieces on a 3t D7 as the D6 9u's back end. So if the brake drum is external to the clutch as 9u oil clutch is it can be ether or, or both brake lining and the drum that has the wear. It would seem the brake lining changed over time, and latter kinds were harder and wore the drum more.

The 9F8992 clutch brake assembly is still available.

Yes there is an adjusting nut for the clutch brake, kind of a big rounded nut on one side nut, I would be willing to bet the lining is shot, those shoes I am sure are available at Cat if not there are aftermarket ones that are just as good I have went to brake shops and had new lining put on and not a lot of money either way

Thanks for the reply. I just took mine apart today. Yeah lining gone pin wore out. Call cat they can be here Friday

Any ideas on clutch brake adjustment proceedure ? Putting it togeather Friday 8-30-2024

These are the instructions for the D7 17As, but should be the same as your 3T.
