Dry Sump Pump Drive Gear Lubrication
Posted: Fri Mar 17, 2023 5:00 pm
Afternoon Lads!
On page 38 of Tuning Twin Cam Fords, David Vizard states "It is possible . . . to get very little lubrication on the (dry sump) oil pump drive gears . . . " He then goes on to describe (with a drawing) how to drill a fifty thou. hole to supply a tiny jet of oil to the gears. This very likely in the context of a four port pump as a few pages later he describes boring out and tapping the oil pressure switch hole to accommodate the high pressure feed from the pump to the oil galleries.
Before I drill the hole to lubricate the drive gears, I'd like to know:
Is this still necessary if I'm using a current five port pump?
Also why are bronze gears offered as an option for the dry sump pump gears?
Thanks much for your time.
