I bought an A-Type overdrive of unknown condition with the intent to rebuild it if needed and install it in my TR3. I bench tested it with 100 pounds of air pressure as described at the end of the "Reassembly" section the Buckeye Triumphs article on A-Type overdrives, and it indicated a problem. Therefore, I have started disassembling it. So far it looks pretty good inside.
I most likely will have more questions as I work in it. My question/problem for today is that I can't get the oil pump to pull out of the housing. Per the Buckeye article and Greasy Hands articles, I removed the pump check valve cap, plunger, and ball. I removed the plug and 2 screws at the top of the pump. I screwed a 7/16-20 threaded rod into the top of the oil pump. I put a 2 inch riser on top of the housing and some heavy washers on top of the riser. I screwed the nut down against the washers with a big wrench but I could not get the pump to pull out. I was concerned that I was going to break something since I was turning the very big wrench very hard. Is there some step I missed to get the pump to pull out? Thanks!
