some B-12 info

[bobvee]

Hello Folks, What fits in the hole with three slots around it in the bulkhead of a B-12?

I believe that you are talking about the location where the hydraulic lift pump attaches.

Correct-the pulley shaft passed thru the center hole & the 3 slotted holes were mounting/belt adjusting holes. The assembly was a self contained pump/reservoir/valve. Bill
