After reading the horror stories of the front diff exploding on brand new Sportsman XP 1000s I immediately ordered a aftermarket billet pinion cover from HD ATV GEAR. I Just completed the install of it and now I can sleep easier!!
It took me about 3 hours to do. My cover went right on without having to shim the Diff.
I used the following to do the install:
*$19 Pneumatic Palm Nailer from Harbor Freight****Two seconds to knock roll pen out with 1/4 Punch in the Palm Nailer. Worked much better than using a hammer.****
*1/4 Round punch to knock out roll pen using the Palm Nailer
*T30 Hex for screws on removal of old cover
*5/32 Hex for screws on install of new cover
*Pure Polaris "DEMAND DRIVE PLUS" Diff fluid and Squeeze Pump.
*COLD BEERS!
Here are some pictures of the install.
