Oil Pump Question - Snowmobile Forum: Your #1 Snowmobile Forum

I was lucky enough to score a wrecked sled with a good motor to replace the blown motor in my 91 Prowler. I switched the engines out today but I forgot to bleed the oil pump. I have put 50:1 mix in the tank for start up. Will the oil pump bleed it self while I run the 50:1 mix out or do I need to bleed the pump?

Bleed the pump! There is a screw in the pump to loosen or remove till oil comes out!

Gotta bleed it or you will be back at square 1.

It's possible that the air will bleed out, but it's also possible that the pump will rotate and not move any oil because of the air bubble. I wouldn't take the chance.

I was afraid I would have to bleed it. Wish I could get my hands on the idiot engineer at Arctic Cat that thought it would be a good idea to put the oil pump on the bottom of the engine where you cant get to it to do service.

There really isn't any service to it! Pull the carbs it's right there!

It's pretty easy if you have an extra hinge in your wrist...

And it's a walk in the park compared to the Polaris IQ sleds. You have to use a mirror and a special tool to adjust those!

I hear you Dan, got it done, only took about an hour and a pint of pricy two stroke oil on the garage floor to get it done. Would have only taken about 45min if I had a extra joint in my wrist. I stick with my rant if you have to adjust it, bleed it, check it, tune it, "IT" should be some where you can see it!

AMEN to that!
