I'm tearing down a 235, block #3837004. Full oil press with alum pistons. The oil pump is held in the block with two pins that have round heads on the outside of the block. On the inside they look like they are threaded??!!>>?? I dont seem to be able to remove the oil pump from the block as it will not budge. I can remove the pick end of the pump, from the gears out but the end from the gears to the block looks to me to be in there for keeps. Any help?
