A: The Pivot Works rear wheel bearing kit for your 2004 CR250R will include the retainer.

A: If you use this link, it will take you to the bearing kit that you need for the rear carrier bearings. Just make sure and select your model information when doing so.

A: yes these are the bearings that go inside the swingarm for the rear axle. mine came with two bearings because thats all that the 250r requires. id say that if motorsport says it will fit your ride then your in the clear

A: it will include all bearings and seals for the rear wheel bearings. and yes that is where your axle slides through

A: yes these are the bearings that go in the carrier for the rear axle, my kit did come with four bearings

A: yes it will

A: This kit will fulfill the requirements of your bike. Each kit is designed to rebuild the specific application.

A: No this kit will only consist of bearings and seals. If you need spacers we will carry those in our O.E.M section

A: Depends on who you take it to. Normally shop rates are about $50-$75 per hour for labor and shops will sometimes charge you the full hour even though it may not take them that long. It's really not the hardest thing to do yourself but I would say at least plan on spending at least $30.00 to have them installed.

A: yes this will include both bearings for the rear carrier

A: In the case of sealed Roller Ball Bearings, they come fully lubricated so, there is no reason to “pack” them. With Full Compliment and Caged Needle Bearings, it’s important to work some high quality, low temperature grease into the needles of the bearings. With Pivot Works Spherical Bearings, if the sphere of the bearing is chrome, it is not necessary to lubricate this bearing. If it is black in color, use a high quality, low temperature grease and work the bearing, turning the inner race in every direction, to fully coat the metal surface of the bearing.

A: Yes, they do come pre-greased. All sealed ball bearings do come pre-greased.

However, the grease used in these and all bearings by all manufactures is not good enough, looks like Vaseline, is not water proof, and is not up to the task of preventing water and mud from entering the bearing, even just from washing, and especially not from a pressure washer or riding.

You should repack all sealed and unsealed ball or needle bearings and even bushings from any manufacture with marine (water proof) grease when used in a dirt bike application.

The grease used by all of the bearing manufactures is not as water proof as a good marine grease. Bel-ray water proof grease is the best. It is very tacky, water proof and stays in place,. I always remove the built in seals on the bearing, clean out the old grease with a solvent (like mineral spirits, WD-40, carburetor cleaner, Gun Scrubber, or brake cleaner), repack the insides completely with Bel-ray grease, and reinstall the seals. I also pack grease between the bearings and the external supplied seals as well as inside the lip of the seal itself. All seals should be lubricated to prevent the inner lip from burning up and allowing water and dirt to pass. The extra grease on the seal and between the seal and bearing helps form a barrier to water and mud getting to the bearings.

You will be surprised how easy it is to remove the rubber seals on these bearings and put them back in without damage. Use a small pick or micro screw driver. The 90° side of a scribe works very well. Carefully pick the outer edge up on the seal and it will pop right out. Do this by poking the scribe into the edge of the seal lightly and pry up gently.

You should do this to every bearing (new or used) on the bike. It should be done wither installing a new bearing, getting a new bike, getting a used bike, and periodically about every six months of riding on installed bearings. This applies to the steering head, wheel bearings, swing arm, shock, and link bearings. It may sound like a lot of work, but it isn't and it is a lot easier and cheaper then replacing bearings and seals

When I get a new bearing or a new or used bike I take it all apart and pack the bearings on all the suspension links, wheel bearings, and steering head. Things last a lot longer and you avoid break downs.

Serious racers do this. It is advocated by those at the bike forums.
