The 2nd test looks at the dynamic function of the pumps. The rig is based on the French reference in post #12 of this thread:
Instead of the "hockey puck" , I machined a rectangular block of aluminum as the fixture that simulates the timing side crankcase, with mounting for the pump and junction block assembly. I used a spare oil tank as the reservoir and connected to the simulated crankcase as on the bike. The pump output goes to a flow restrictor the output of which empties into a container that would effectively be the engine sump. A pressure gauge measures the oil pressure in the line from the pump output to the flow restrictor. The return side of the pump is connected to the container which supplies the pump with the oil that it should return to the tank.
As in the French reference, the pump is driven by a variable speed drill which connects to the nut that holds the worm gear. I used a hose clamp to hold the trigger in various positions, adjusted by turning the screw on the clamp. A hand held optical tachometer was used to measure pump rpm.
This rig can test both feed and return function of a pump.
For the feed side, I would take measurements of output oil pressure at various pump rpm from around 300rpm to around 2500rpm. I believe that engine rpm is roughly 2 1/3 times the pump's rpm, so that gives a decent range of normal engine operating speeds.
For the return side, I connect the hose from the feed side that went to the sump container to the breather input to the tank. With this connection, the feed side just circulates from & to the tank. Then, I measure the amount of time it takes the return side to remove a specific volume of oil from the container. From this, I get a flow rate for the return side, at a given pump rpm.
I'll post the results of the testing tomorrow.
