Hello all, I am getting ready to pull off the right side of the case to change the waterpump seals and bearings in my 2001 Polaris Xplorer 400 4X4. While I am there I wanted to inspect the Counter Balance and CB Bearings as there was coolant in the CB oil.

I just got the OEM maintenance manual looking at the steps involved. One part is unclear and need someones experience that has done this before.

Question is do I need to pull the oil pump to remove the CB assembly or to re-install the CB assembly? Also how do you press the CB back in one it is pulled?

Many thanks for any help you can provide.

Yes you do need to remove the oil pump. You will also need a counter balance puller to remove it. Once you get a new counter balance or have it refurbished simply tap it back in with a socket and hammer.

Do I need to heat anything for the removal or re-installation?

Also what part of the CB should I tap on to put it back in?

There are two different spots to heat near the oil pump, (One on top and one on the side). Link to the manual http://www.polarisatvforums.com/for...nance/34483-owners-service-parts-manuals.html. I just used a large socket 3/4 in the center of the CB, a piece of wood on top of the socket and a hammer to tap it in while the ATV was laying on it's side. I had my counter balance refurbished by 440rupp on ebay for $150. He did a very good job and the turn around time was excellent!

i managed to refurb my CB shaft myself, matched up the bearings at a local specialist who managed to find some off the shelf NTN units ($35 for the 2) and popped them back on with a press, the drive gear came off and went back on pretty easy. if you have access to a small press and a good bearing supplier I say go for it.
