    2003 Polaris MSX 140 - oil pump cable installation

    What is the proper way of setting the oil pump because when i replaced the reeds I had to take the cable off that runs to the oil pump and don't remember how it was set?

    Welcome to the Hulk

    Not sure what you are asking. The cable pulls the oil pump arm up against the spring tension of the pump arm.

    Note the small line embossed in the hub of the pump arm, and a similar line on the oil pump body. These two marks should align when the throttle is at idle. You need to use a small mirror to view the marks for alignment.

    I adjust the oil cable so the pump arm mark is just a line width 'more' when the throttle is at idle, which means that the oil pump will flow a little more oil than spec.

    Did you remove any of the oil hoses? If there are air bubbles in the oil hoses you need to bleed the air out.

    For the oil feed hose from tank to pump, just crack open the bleed screw right on the oil pump. The oil will flow via gravity and push the air out. Tighten the bleed screw again.

    For the individual small oil hoses, find something like a syringe or tiny funnel. One by one pull one end of each small hose off and fill it with oil, then reconnect.

    OR dribble some oil (not a lot, just a dribble, maybe a teaspoon) down each throttle intake. Then run the engine at idle on the hose. Manually pull the oil pump arm all the way forward while the engine idles. You should see the oil push the air bubbles through. It doesn't move all that fast, even with the oil arm pulled to 'max'.

    Don't forget to limit engine run-time to less than 2 minutes on the hose, then let it cool down. This protects the drive shaft seals from overheating.
