Bench testd my 71 Commandos scavenge pump and with my drill running it at 400 rpm, it puts out 8 oz per minute at room temp with 20W50 oil. Its set up to mimick its function in the bike lifting the sump oil about 6”” to the pump and pumping it up about a foot to the top of the oil tank.
As best i can measure the axial clearance of gear to endplate is about 0.002 to 0.0025”. This is too much but i wanted to get a baseline to see how much i can improve it by lapping the body of the pump as the shop manual describes.
Anybody else have any flow rate info on the scavenge pump??
