Fredricks seems to lost some Part#. If you look at their website under Misc. I would think they would have it

I know. The studs are larger than 14mm and smaller than 16mm. We measured them at Fastenal and they were 15mm. They said they were probably made only for Yanmar.

As last resort you could take a long stud to a machine shop , have threads extended as necessary and cut to correct length.

I called Fredricks yesterday and they said they may have a used one. I'm waiting for them to call. I thought about cutting the long stud but have been told the steel is too hard. Cutting is no problem threading is the problem.

On second thought if there are no 15x1.5 mm studs there won't be any 15x1.5mm dies either. I'm surprised Hoye does not have used ones, given the abundance of YM240-YM2000's

If you don't hear anything check into using a Helicoil insert. It's worked for me before.

This cant be that hard and they have to be availible, they should be replaced when doing head work right? how then can hoye and Fredericks work on yanmars and not have a source of studs?

 

[clemsonfor]

can you call yanmar marine or yanmar usa?? this is a USA model tractor!!!

Or go over to the guy who sold it to you and donate a half day of labor to clean up his shop. The stud should be there somewhere. (and the long one for the radiator support).

Apparently they won't fit anything else.
