Yep. Bolt it to a 1/2'' or thicker plate. I clean it and cook it when tig welding to give the oil time to come out.

A good acetone soak (standard TIG prep) and dedicated stainless brush and burrs uncontaminated by other metals are the way to go prior to the wise advise to cook it well. Preheat is your friend including the plate supporting the casting which can act as a heat sink. Small welds allowed to cool will stretch while larger welds can easily crack.

Practice on scrap first. I am not a TIG guru but there are plenty on the Weldingweb forums (which are to welding what this place is to choppers) who can also advise on newer filler metals.

I started using flange sealant on inner primaries instead of o-rings. It's designed for such jobs, bonds which rings do not, and conforms to the joint. It's harder to remove (don't use it on inspection covers).

Agree with not using the o-ring. I myself have not used one there since 1980. When you bolt up leave the trans nuts and bolt loose till you have the primary tight to the rans and engine. Unless it was together and working, in which case , if you are just removing and re-installing it you do not need too loosen the trans to allow it to find it;s happy place.

There are literally thousands of used inner primarys out there. They do not have much value and instead of fixing the old one get another one that would be new to you.
