Source for valve cover studs

Postby arlen » Sun Feb 28, 2021 10:19 am

Anybody have a source for valve cover studs? Mine currently are just 3/8 all thread.
My visits to Napa have been fruitless.

What are they supposed to be.
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

not familiar with a B if they are special, look at Hardware web sites, such as fastenall and see if they have what you are looking for, just need the thread size and lenght

They are about 4.75” long, 3/8” diameter with about 3/4” coarse thread on side and about 1.5” of fine thread on the other side.

That’s what I’ve been doing with no luck so far. I was hoping some one else has actually been successful, and was will to share their source.

Try McMaster-Carr online. FWIW, those studs should be the same on all C-113 and C-123 engines used in A, Super A, B, BN, C, Super C, etc. You might also try JP Tractor Salvage, one of our sponsors. Link at the bottom of this page.

Have you checked with CaseIH? Messick's doesn't show them on hand but does seem to indicate they are available. For about $10 each, how much running around looking elsewhere is worthwhile?

Since you don't have the originals for those two, check your center stud. It should be hollow. And be gentle tightening the center one, it is easy to twist off.

Thanks for that! I didn’t realize that they had so many parts available. I just ordered a couple along with a carb kit for my TSX-157, and a couple other things. About $220 al together :shock:

About the center stud... I verified that it is hollow. I noticed that it is tightened down where the hole is slightly counterclockwise from center, which looks like it is supposed to be that way.

I don't think it matters which direction the hole in the side of the stud faces. There is room enough all the way around for oil to flow. The hole in the end, of course needs to be down.

It used to be that auto parts stores would have a display rack with the various studs, just select the ones you need. But a couple years ago, I was working on a project required a couple different size studs and was really surprised to find that they are really hard to locate. Even McMaster Carr and the fastener suppliers had almost no selection. I ended up making my own. cut off long bolts and thread the other end. If you can't locate them through the usual sources, making them is a possibility.

I think a lot of people feel that these tractors are so old that the manufacture dont make parts for them anymore.

It never hurts to see if the part is still available from the tractor dealer.

With probably over half a million c113 & c123 engines produced, I would say there is a strong desire for parts!

I saw on another post you made regarding the center stud, where you mentioned "a very important flat washer" Mine didn't have a washer installed, and I didn't see one in the parts diagram. Is it supposed to have a regular flat washer, or is it supposed to be some type of special machined washer?

I don't know where I got the flat washer from. I'm sure they have been on engines I have worked on. The Parts Catalog shows no washers, just a nut. This suggests to not add a lock washer either.

I appreciate the post.
I wasn’t sure, and given that there was all thread used on the other 2 mounts, and a couple long bolts used in place of head studs, I didn’t want to make any assumptions on how mine was put together! :D
