Hi,
while rebuilding a 345 engine, I put in a rebuilt oil pump.
Before installing the pump, I immersed it in oil and spun it by hand. It turned easily and sprayed oil.
When installing the pump, I used paper gaskets under both mount points
now the engine is in the Scout, and the oil pump seems difficult to turn and does not seem to turn freely. First, I was spinning it with an old distributor and a drill. My drill was working hard. Made plenty of oil pressure, but it felt like the oil pump was not turning smoothly. I thought the drill might be working due to the oil pressure, so I tried turning by hand and it the oil pump feels like it is binding.
The only thing I can think of is the bronze bushing in the front of the engine that supports the distributor shaft is binding.
Any ideas?
Thank you in advance,
ken
