064 oil pump

[cottonwood1]

Have the 064 I have all apart. I am looking at the oiler is there a way to test the oil piston to see if it is working when it's apart? Not sure if that is bad or the nipple that goes into the oil pickup line from the tank and that seems lose fitting to me. If the pump is bad can't you just replace the piston guts instead of trying to find the whole oiler? With that my oiler part number doesn't seem to match any I do find. Any list of 064 oiler part numbers? Thanks a bunch!!

They rarely go bad.

They were NLA and recently became available again I have been told. Not cheap, north of $100.

I’d check everything else first, including the output grommet.
