The wheels of a your scooter take a lot of abuse. Even though the relative diameter of your wheel limits the abuse to your wheel bearings, they often end up picking up a lot of dirt and will need replacement. This guide will show you how to safely replace the wheel bearings in your Evo, but this guide could be applied any 4" split rim wheel.

You will need

  • 2 new 6002 bearings
  • Crescent wrench
  • 17mm wrench or socket
  • 11mm socket driver
  • Metric [allen wrench] set
  • Oven

Remove the wheel and split the rims

Deflate the inner tube as much as possible and use the 11mm socket driver and the appropriate hex key to remove the bolts holding the rims together. The tire might stick a bit, but it should fall off fairly easily.

Use the oven trick to remove the bearings

The bearings inside the rims are pressed incredibly tight. Use the oven trick and the 11mm nut driver to press out both bearings.

Get the new bearings in

Getting the new bearings pressed into the wheel is a bit difficult, but a trick that can be easily managed with the tools you already have.

Making a press

Take the two halves of the wheel and place them on the wheel bolt with the new bearings lined up against the wheel and the old bearings outside of those as shown in the picture. The hold bearings will take the load of force so we don't end up damaging our new bearings.

In the picture I used an extra old bearing in the right since I was replacing the bearings in both wheels at the same time and happened to have it handy. If you are replacing one wheel's bearings you might as well be replacing the other's.

Compress the press

The bolt itself should keep your bearings straight as you press them in, but take it slow to make sure things go in right. It should not take much force with our added leverage to push things into place.

Cleanup and reassemble

Since you have your wheels apart, you might as well give everything a good cleaning. You can use an engine de-greaser on most everything, but on the brake disk, you should use something which won't won't leave a residue like carb/brake cleaner.

Don't forget to replace the black aluminum spacer

The black aluminum spacer takes the pressure off the bearings. Don't forget it!

Don't forget to put the black aluminum spacer back between the rims when you reassemble. That spacer takes a load off of the bearings so that they can roll more freely.
