Oil filter routing 1940 Farmall A

Postby Bernie Dueck » Thu Dec 20, 2018 1:31 pm

I am rebuilding a 1940 Farmall A. As I was following the oil flow channels to be sure that everything was open I had open channels into the base of the filter canister but found no way for the filtered oil to get out of the canister. I am used to the center bolt having a hole up the middle and then a hole through the side of it partway up to serve this purpose. My center bolt had neither of these. It looks original otherwise. How is this possible or am I missing something??

The bolt should be hollow. Either a plain bolt has been substituted or it is completely plugged.

Thanks for the confirmation. I drilled it out and in on side. (It had a dimple at the right location for the side hole)I was drilling solid steel all the way on both! The bolt has the appropriate shoulder just under the hex head and looks factory.

I wonder if that one was accidently not drilled out and got installed. :?:
