Everything on the back-end is stainless - except the coupling that came from Beta - I don't know what grade they are. Also, everything (even stainless) gets Lanocote since it ensures easy (although messy) disassembly in the future.

If they're old, it certainly is a good idea to upgrade the bolts on the coupling. They don't have to be stainless especially if they're coated.

You do not want to use stainless bolts. SS bolts are not as strong as mild steel. SS is maleable and will stretch and loosen with shock and vibration. Might not be a big problem with the modest torque loads on these small diesels, but it is not recommended. The numbers on the bolts are about strength and there are specifications somewhere about what should be in the coupling. I think the engine or transmission folks will have the specs on the coupling bolts you should use.

Well, ok. The numbers are no longer readable on the bolt heads. I'll ask my mechanic (and the rebuild kit supplier) and see if they have any idea.

Thanks, guys-

Ray

Look for the number of lines on the bolt head. I think 3 is the minimum for that application.
