Mikuni Oil Pump

[TIKI]

I want to go through the Mikuni oil pump on a 1971 TM400R, any suggestions on where to find the O-rings and seals for the pump?

We did this a while back for the T250/GT250/T350/T500/GT500 oil pumps. Most of the o-rings & seals were pretty common & easy to get. But one wasn’t easy to find.

The screw on the T250… pump, which is used to prime the pump, has left-hand threads because of the pump’s rotation direction. So be careful with the screw on your pump that is facing the camera in your pic — it may have either right-, or left-, hand threads.

Good place for o-rings: http://www.theoringstore.com

I would have to lookup the sources for seals. So if you have troubles finding the seals, let us know & post the sizes.

Thanks jabcb, I ended up doing a little research and found all but one O-ring available on Partzilla through Kawasaki the pump looks identical to mine. I placed the order and hope it’s all correct when it arrives.
