Cat 12 9K Grader U Joints for PTO Shaft

Must be an odd ball for sure. No aftermarket interchange listed for 9K1-up or for 7T1-3099. Most all the other 12's and 14's use the same u-joint.

From Pg. #143 of 9K1-9K2000 Pts. Book:

2- CROSS & BEARING ASSEM. 6F9741

This for Drive Shaft Assemblies 7F2617 (replaces 5B43😎 and 8F3786 (replaces 7F2617)

Might be a few of them out there....

Thank you to all very much, I just talked to my pal and he said he went to a different company Cat dealer today and they had the Microfishe viewer still and showed the joint, washers and caps separate but the caps not available but sold him 2 6F9740 cross's and the washers but didn't know if cross was complete with caps, well I bet they won't be and you guys have the correct number. They overnighted them so he will see tomorra..

I truly appreciate all the help and the prompt replies, I did not look until just now but wow you guys are tops for helping on this old metal

Hi hg,
it is possible those joints are Blood Brothers in origin.

I note you have drive line experience, so if you have no luck chasing down the correct parts and seeing as the drive has 4 bolt flanges at each it would be possible to make or purchase adaptor flange plates to adapt in later available pattern joints. Have done this on vintage trucks etc. in the past.

At The Dealer we had a range of adaptors to adapt drives to transmissions, hyd. pumps etc. on our Wolff Hydraulic Test Centre as well as some for our Taylor Engine Dynamometer.

Cheers,
Eddie B.

I don't have the parts book to check it out but it may be possible to change out the entire flange to flange drive shaft with a later, more common unit.

I had the same problem on a 212 grader, the original caps were brass and turned directly on the cross without needle bearings. I solved it by swapping in a 212 shaft from a year or so later unit that used used the "mechanics" style joint. I got the joint at NAPA, you might be able to try something similar.

I don't have the #12 9K parts book but here is a #112 3U that uses the same odd ball joint.

I can provide grader models that use the later common U-joint if desired.
