Thanks for the numbers OM. I hit a dead end on them. I'm hoping Capital Clutch can help me out.

Might check in with General Gear in Idaho. They don't list anything for the 212 but they may have some useful information. They seem to be interested in stocking clutches for the old stuff.

Yup. General Gear. www.tractorparts.com/ I was in their yard several years ago while on a trip from NY to California and back. Nice folks. Lot of good stuff out there in the desert. Would like to that again someday. Dandy Dave!

I had a 53 model 212 grader that the clutch disk had been replaced on the center hub. The replacement disk had the linings bonded to the steel instead of riveted on. I had ordered a set of linings from CAT before I took it apart but when they wouldn't fit and the old ones were pretty thick, I just cleaned up the teeth in the flywheel and pressure plate and put it back together. I ended up trading the grader off several years later still running (barely) on the aftermarket clutch. I didn't take it apart again, pressure plate could have been stuck again.

That was the first CAT engine that I acquired that had sucked up roll pins etc into the oil pump. The second one was a D333 in a 12E grader that had a sheetmetal lock plate caught in the pump gears. In both engines there were still roll pins left (not sucked up yet) in the suction bell of the oil pump when I took it apart. Obviously, oil pumps do not fare well having ingested a hard steel item and do not deliver much oil thereafter. Amazingly, the D311 was still running with no knocking, just no measurable oil pressure. I was able to clean up the oil pump gears and housing and reassembled it. It made good oil pressure according to the CAT gauge in the cab and is still running today as far as I know.

If you don't have a shop close to you, I have had great service from Automotive friction in Birmingham, Alabama.

I have exhausted my search for all 3 PN on the clutch plate and had Capital clutch in Sacramento build me one and turn the flywheel. THEY DID A GREAT JOB. They fabricated a new clutch disk and turned the flywheel in one day. Now I am getting set up to reinstall the engine in the grader next week end. Thanks for all the good advice.

Great progress!!! Would you mind sharing the cost information on those services. What did you do about the levers?

The ring gear is bolted on to the flywheel, the same ring gear is used on the D4, U, some of the J series, etc, the pinion same as D2, D4.
