It’s best to have the next gadgets: (2) wheel hubs, (2) smaller tapered bearings, (2) giant tapered bearings, (2) wheel bearing nuts, (2) dust caps, (2) internal bearing seals, (6) M3 x .5 screws, (2) cotter pins, (2) inside bearing spacers
2. Completely remove the old wheel hubs from your quad and clean the spindle and the encompassing areas. It is rather vital to maintain the brand new bearings and seals clear throughout installation for long life. Make sure to take away the manufacturing unit interior bearing spacers from the spindle and discard. They won’t be utilized in re-assembly.
3. Pack your new Timken tapered wheel bearings with a liberal amount of top of the range wheel bearing grease. A wheel bearing packer works greatest, however you may accomplish the task by placing the grease in the palm of your hand and manually working it in between the bearing rollers. We additionally recommend that you just pack the realm between the bearing races within the hub with grease for additional lubrication and protection in opposition to moisture.

8. SETTING THE BEARING PRELOAD: It is first necessary to seat the bearing earlier than setting the preload. This aligns the rollers and prevents the bearings from loosening after a brief period of use. To seat the bearing, tighten the spindle nut while you rotate the hub until the wheel hub turns into difficult to spin. With the bearing now seated, you need to set the bearing preload. Preload means inserting a small quantity of pressure in opposition to the bearings to remove any clearance between the bearing race and the rollers. That is accomplished by backing the nut off completely and re-tightening it with your fingers. Don’t rotate the hub while setting the preload. If a gap within the spindle isn’t accessible for installation of the cotter pin, modify the nut tighter to deliver a hole into alignment. Set up the cotter pin and bend the pin across the exterior of the nut. Do not try and bend the pin towards you (over the end of the spindle) or it could rub on the inside of the dust cap.
