Testing a Snowmobile Oil Pump

When it’s cold I can’t wait for warm weather, and when it’s boiling hot, as it is today, I can’t wait for the return of cool weather. I’ve been daydreaming about the snowmobile that is currently summering in my shed, and thought I’d use today’s post to explain how to test a snowmobile oil pump. An oil pump, for those unfamiliar with the mechanism, keeps the engine properly lubricated.

To test a snowmobile oil pump, start by disconnecting the threaded fitting on the oil pressure sending unit tube. You’ll want to use a wrench. Take your oil pressure test gauge and attach it to the port on the engine block. Start the engine and take a read out of the test gauge. A normal reading means you’re good to go whereas a low reading may indicate that the pump needs to be replaced.
