HELP!! 1999 MXZ 600 Oil Pump Question?? - Snowmobile Forum: Your #1 Snowmobile Forum

I need HELP, please!!! I have a 1999 MXZ 600 with a bad oil pump. I have pulled off the oil pump and it doesn't match the new one I received. I think the one I received is from an '03 MXZ 500. Does anyone know if these two pumps are compatible performance wise? At this point in time, I don't even know if the "new" one will line up with the cast. I have tried to research these two pumps online and I have not come up with much. THANKS!!

they are different for a reason

I had that feeling. I know that the original pump on the sled does not flow at idle...maybe that is the difference between the two. Thanks for the response.

They don't flow at idle,that's the way the work from the factory.
