Hey All,

I'm looking for a little help tracking down new D2 pony motor head to manifold bolts. The updated part# is 5B-8857 (3 and 3/16" long 3/8 inch N. course on one end and N. fine on the other). The CAT dealer still has the number in the system but said they don’t stock it as it is now discontinued!! If no one can help, I guess the only other option is to have a machine shop turn some out. This is a last ditch option as it is REAL expensive for four bolts.

Thanks for any info/ideas,

J.

I made some studs similar to what you describe some years ago by buying high grade bolts in a longer length then cutting the head off and threading the cut end to the fine thread. It was for a pump application and it is still working. I would think a 4 to 4-1/2 inch bolt would work for you.

or go to cap screws like the late pony motors.

I'm sure I have a few studs saved from a junk block. I will be home in a few weeks if you aren't in a big hurry.

Try McMaster-Carr for Stud Bolts

I found mine at the local hardware store. Traditional service same family owns since 1960's. Kleindorfer's Hardware, Bloomington IN. My son brought the studs in with him to match up-I think they had the match. No problems with clearances or fitting the nuts, other than the tight space.

Florin Tractor in Sacramento CA shows they have 96 5B8857's in stock. Phone number is (916)383-0317. They are nice folks to deal with. Hope this helps you out.

Thanks for all the help... got it covered now !!!
