Pivot Works Z400 TechReplacing those old and worn rear axle bearings

Source: ATV at Off-Road.com
When inspecting the rear swingarm on our Project Z400 for the new DuraBlue axle, we discovered that one of our rear axle bearings was no longer rolling as smooth as it should. (Anytime you replace the axle, it's a good time to check your axle bearings.) We contacted Pivot Works for one of their rear axle kits for the Z400. Pivot Works builds a whole assortment of bearing and seal kits for many models of ATV's. These kits are excellent quality and much less expensive than buying OEM replacements from the dealer.Installation First thing you need to do is remove your rear axle. With the rear axle out you should remove the dust seal. They make a special tool for this but since we did not plan on reusing the old seal, we just used a screw driver to remove it. With the seal out, we put a bar with a hook on the end inside and knocked/pulled the old bearing out.
This is the dust seal and bearing with the axle removed from the swingarm.
We removed the dust seal with a screw driver. Use the special tool if you need to reuse the seal.

With the dust seal out you now have access to the bearing.
We used a bar that has a hook on the end to pull / know the old bearing out.
 

The OEM axle bearing was sealed only on the outside. The new Pivot Works bearing is sealed on both sides.

We found that the OEM bearing was not sealed on the inside. This may have something to do with it going bad, but the bent axle probably wreaked more havoc. The new Pivot Works bearings are sealed on both the inside and the outside. Prior to reinstalling we cleaned out the swingarm where the bearing sits then put a light coat of grease on there and the outside of the bearing. We then used a soft faced hammer to knock the new bearing into place in the swingarm. With the bearing all the way in we coated the new seal with grease then used a block of wood to knock the seal into place.

Make sure to put some grease on the new dust seal before installing it in the swingarm.

Now reinstall your rear axle and you are ready to rock again.
Summary The Pivot Works bearing and seal worked perfectly and was much less expensive than the same OEM part. We like that the Pivot Works bearing are sealed on both sides. The job took less than an hour including putting everything all back together. (But we should point out that we already had the axle out, which is the hard part on an original.) If you have some bad bearings or seals we recommend you check the availability of replacements from Pivot works before you head to the dealer for OEM parts.
