Can someone provide the correct gear backlash and pinion bearing pre-load values for the RZR 800 rear differential?
Polaris does not cover it in their service manual and I have had no luck finding the Manufacture's service manual for the Model 26 Independent Suspension used in RZR 800's.

Per HPD instruction sheet:

"Preheat the case and tap the bearing races into the case. Allow case to cool. Shim pinion bearings for a bearing preload, measured by torque, to rotate with 7 to 12 in-lbs, when lightly oiled, without seal installed. Torque pinion nut to 275 to 300 ft-lb. with Red Loctite.
Shim the right hand spool bearing for contact patch and .0035" to .007" backlash.
Shim the right hand cover bearing for a bearing preload of .0035" to .007"
