Any idea what the flow rating of the GMC pump is? I prelubed/flushed an engine using an external GMC oil pump and it smoked my B&D 3/8" drill.
It takes a few seconds for oil pressure to come up on my Reo six and you can hear it load the engine down. That pump is 15gpm at 3200rpm. It is probably approaching the limit for a right angle helix drive.
