I'm doing a rebuild and have the head off. In looking close at the long studs that hold the hydraulic pump, there is a crack in it. It doesn't look like any M42218's are available. Any ideas?

I used Grade 8 carriage bolts and cut them to length. I had to order them from Fastenal but pickup at a local branch is free so they weren't that expensive.

You will probably fight the stud to get it out... good luck! Make sure you chase the threads in the block also.

Between JD parts and the service manual, I am still missing something here. Is the pump mounting plate sandwiched between fiber washers or is there some kind of spacer that goes in there as well?

I put a regular washer on top of the nut then a fibre washer then I turned down some smaller fibre washers to fit in the plate to keep the plate from moving then another fibre washer on top followed by a regular wager a nut like it shows in the service manual. Bought all parts at hardware store. The real parts are NLA.
