I just pick up a 1975 MY250, that has been completely rebuilt, but has a few things that need to be put back together. Wireing harness, Engine side covers, injector pump. I'm having trouble finding anything on how to put the pump back on the bike. I put the Plastic gear with Swaft back on the bike, trying to figure out how to line up the Pump gear with the shaft to get the pump back on. Also I'm not sure if I'm missing parts.

Any help will be greatly appreciated. Thanks


Here is what I have..

Pretty sure the pump isn't serviceable so shouldn't be missing parts
Put it back in by aligning the keyway - once on you must bleed the pump once hose connected back to the tank and put some oil in
the bleed screw is top left hand side of the oil pump housing - needs to be undone until oil pours freely
The tighten
You then need to align the marks on the pulley to the one on the bottom of the pump housing when the throttle is fully closed
Then run at low throttle until oil fills the transparent tube to the intake manifold -
