The Arctic Cat rear end has a larger diameter tube and the gear case is different, and also the location of the fill holes and the whoozit.

Before we went riding this weekend we checked mine and my seal was pushed out some, so we tore it apart and the bearing and seal were shot, the bearing hadn't locked up yet but it was definitely close way too close. Hardly any grease and full of slime.

We have come up with a possible fix to save all input shaft seals (new rearends and old), still working out the details, tested ours this weekend, performed excellent and prevented weed wrap. More info later Aczr2k

 

How do you tear it down tho?? Do I have to remove the axle from the swing arm?? Do I have to remove the axle tubes?

BTW: I know a few people that have drilled holes in the rear end and added a gease zerk to grease the bearing every now and then.

 

Easiest way to tear it apart is to jack it up, put blocking under the mid section. Remove the wheels, unbolt the brake calipers, remove the hitch w/skidplate. Unbolt the shocks on the axle housing and the radius rods. The rear end should be free by now then just pull towards the rear, this will pull apart the driveshaft, It is splined to the stub that comes out of the rear of the motor. Put it up on the bench, it is much easier. Slide the rubber boot off, remove the 4 nuts that hold the bearing housing on and remove the housing. You should be able to push the shaft out of the bearing. Remove the seal, remove the snap-ring that retains the bearing and then press out the bearing. Clean everything up and fill with grease, install new bearing and seal and reasemble. In and out takes a little under an hour.

We thought about putting in a grease zerk but if it was over greased it could press out the seal, because there is nothing holding the seal in other than a "light press fit". The housing could also be machined with a snap-ring groove to retain the seal. Aczr2k

 

Thanks alot man, I guess I'll see about doing that after I get my other parts. Well after I get enough money to pay for all this crap.

 

Price isn't too bad about $13 for the bearing 8 for the seal. And you can get them from places other than dealer. 52mm outer dia, 25 mm inner. Aczr2k
