Installation Instruction for JAY PARTS Pinion Cover HD Highlifter

Unfortunately Polaris has not only the problem until the year of construction 2017 that the flange on the screw connection breaks also the bearing seat is not designed enough and it can be on the bevel pinions an elevated wear occurs. In Polaris update 2018, the material was changed, but the bearing seat unfortunately is the same bad.

WE RECOMMEND THE INSTALLATION BY A PROFESSIONAL WORKSHOP.

ASSEMBLY

To assemble the cover here are some important and helpful points:

As a first step you should drain the differential oil (screw down the Front Differential)

• pick up vehicle
• disassemble the front right wheel
• with the punch through the spline of the propshaft (connection between propshaft/ differential).

Push the propshaft backwards – remove the original flange (4 screws) – pull out the drive pinion with the bearing.

Check the bearing for noises. Swap the supplied SKF roller bearings of the pinion, as these usually show wear!

Difference to the original:
The bearing (with the bevel pinions ) must be pressed in because it is one of the most important features of our cover to minimize wear. Do not hit with the hammer!

Use a little grease for the needle bearing, oil seal and o-ring.

Then built the pinion again in reverse order together.
After assembling the differential turn the pinion in both directions. It must be easy and must not have a game.

DO NOT forget to fill the differential oil, capacity 275 ml (Polaris instruction) – our experience: 190-200 ml

ATTENTION

Use ONLY the original POLARIS DEMAND DRIVE OIL!
