well started looking at the oil pump that came on the car

looks really clean in my opinion, and very little surface wear on any of the internal walls and inside face of the cover.

assume the gasket is super thin ? as it looks to be there but caked to the pump. maybe 1/64 or so ?

some shots of the inside of the cover as well as the vanes and guts...

ok and now the spare oil pump...

few shots of the outside and case

now spare oil pump inside cover and guts

tore down the two pumps a little further today.

on the original one, the shaft and the end that is held in by a pin is sloppy ?!? has a few degrees of free rotation, i can hold the end and turn the shaft a little bit before the end turns, and i can push/pull the shaft about a 1/16" or so before it engages and pushes/pulls the end. not sure how much play there should be in either direction.

this is the connection (shaft and end) i was referring to in previous post that is pinned together

put all the pieces for the original in the parts cleaner for now and will let it soak and clean for the night, then check it all over.

then do the same for the spare.

may take the best parts and build one pump, and then build a spare from the remnants for emergency or spare parts down the road.

can i just drive out that pin and pull the end off the shaft ?? then check for oblong/worn out hole ?? then could i drill it out and put in an over sized pin or what other options could i use ?? remove pin then drill housing and shaft 90 degrees out from existing pins & hole and put in a new pin same size as now ??
