I have two problems with my 500. I plowed snow with it this winter. I plowed a lot of snow. The front left half shaft is rattling in the diff. I have no output to the front left wheel. I went to the Polaris dealer today. They weren't a lot of help. The parts break down doesn't show parts for the front diff. Next...I think I have a fuel pump problem. It back fires, runs poorly, basicly won't run. I have read some posts about fuel pumps on the 700, and 800 EFI's. Anyone have some help on the 500?
Also....I wondered about pushing snow in low range. Is this locking my front diff and causing problems?

 

You can find your parts breakdown at Polaris Industries - -
http://parts.polarisind.com/Browse/Browse.asp

The front "differential" is found under Housing, Front (Demand Drive)

As for the running problem - have you tried changing the spark plug?

 

Low is what you use for plowing and the awd has nothing to do with high/low range in its operation. As soon as the ATV is a 05 or newer I think of that cheap plastic roller cage in the newer front diffs as the culprit.

 

Thanks for the input. The plug is fine. Air filter is clean. The fuel filter is clean. I don't know what the fuel pressure needs to be. They do make it easy to check fuel pressure.

 

you need a special gage to read the fuel pressure i do beleave. there is a test where you pump fuel into a container and messure the amount in a certain amount of tiem to determin if the pump is pumping right. make sure theres no codes and you have good connections and good grounds.

 

Larmo, maybe I missed it but you didn't give us the year of your 500 and is it EFI or carb?
