Default Oil pump drive

The teardown of the newly rebuilt engine (30 years ago) continues. Take a look at the oil pump drive. Can anyone tell me the clearance reccomended in the photo below, and if the top piece should have groves on the underside for slinging oil? Clearly things do not look good for 10 miles running time. Looks like the gear is evidencing metal fatigue.

I can't answer your questions, but I can say if I pulled out a unit that looked like that I'd just replace it. New ones are cheap, well made, and readily available. Go see Tom at The Ford Works.

It looks like they just put the old worn-out gear back in during the rebuild. That thing is shot and should be replaced. The gap is determined by the relationship of the gear and the lower retainer piece to the cast body and is usually around 0.006-0.010 inches. The lower retainer piece has shallow criss-crossed grooves cut into the bearing surface and the gear has a spiral groove along its shaft.

That poor thing is eaten away by rust and/or acid in the oil, it should be replaced. How are the gear teeth on the cam? I would question the general quality of the rebuild, unless it was a hard 30 years of storage.

I've posted other photos of the engine - search for Rubatoguy as the poster. When received the engine had a knock and was taken to a local bay area shop - Mal's A sales, who discovered the oil pump broken off just past the entrance to the block. Also the center main had 6 thousands clearance, and there was a rag blocking the front bearing galley. It is a B block. Because of overheating, the engine was not run more than 10 miles, and then when my Dad got sick and later passed, it sat in a garage for 30 years before I got it.

Is the Ford works still in business? If you search the web it says they are not in business and the google photo of the location has a big sign that says "For Lease." If they are not out of business, they should correct the bad information.

sounds as if the "rebuild" might have consisted of rings and a valve lap, if that. "Rebuilt" is one of those words like "restored" that can have a different meaning to the seller than it does to the buyer. What do the main bearings look like? You might consider having it rebuilt for real.

I agree there is just too much wrong for it to have been rebuilt by anyone taking money for the job.

I grew up going to Mal's as a kid in the 70's. They just don't have places like that anymore. Thanks for sparking that memory
