Improved wheel bearing with longer axle

This upgrade kit makes the wheel bearing much more durable than when the wheel motor was new.
Poor wheel bearing puts a lot of stress on the gears and causes them to wear out prematurely.
Axle and wheel bearings always wear out on these motors and then this is a very good upgrade that gives the motors a long life.

This kit is mainly sold together with a repair kit for the wheel motor, but can also be purchased separately if the wheel bearing needs to be upgraded afterwards if you bought a simpler repair kit on a previous occasion.
If the motors have not been repaired before, it is recommended to buy a repair kit with improved wheel bearing instead!

This also fits perfectly if you drive with double assembly on the wheels.

The shaft seal is mounted in the plastic bracket with the spring facing the electric motor and lubricated liberally with grease. The old seal must first be removed.

320/330X/420/430X/440/450X/520/550 2014v45 and up
435X fits only the axle with large wheels.
