Does anyone know if the track drive bearing on the speedo side comes out via the clutch side or do I have to remove the entire shaft via the track side and chaincase. Please help I plan on getting the parts tomorrow.
 

you can pull it out from the speedo side, you don't have to remove the whole driveshaft. Just loosen the track as loose as it goes so that you don't have to fight all that tension pulling on the bearing. There are two set screws on the bearing collar inside the tunnel as well. Then just get a big flat screwdriver between the collar of the bearing and the collar of the driver and twist it, bearing should pop right off if it isn't seized on there. ;)!
 
track bearing

once I install the new bearing is it possible to remove the seal and speedo housing from time to time add new grease a couple time a year?
 
I just did mine in my 01MM700 and let me tell you it was not fun..That collared bearing was very seized on the shaft. I did everything I could think of. I ended up pulling the whole shaft and using a bearing puller. Look around for a replacement bearing. They are very common. 6205 seris bearing. Just make sure it is the sealed collared one. I did both shaft bearings chaincase and speedo side, as well as the oil seal in the chain case for $30.00 cdn. If you have it out, I think it might be worth your while to do both. Just my $.02.
 
I forgot to mention that you shouldn't need any grease on the speedo side due to the fact that this is a sealed bearing. That would be why there is no grease zerk.
 
One way to never have to go thru it again is to simply drill and tap the speedo drive and install a zerk fitting, then pop off the seal on the speedo drive side and now you have a greasable bearing that will outlast the sled, been doing this for a long time. A few pumps of grease every 1000 miles and it will last forever.
 
There are other manufacturers that have that same set up with the zerk and it seems to work well if you remember to grease it.
 
yes but be VERY careful not to overgrease it if you do that or it will push the seal out the back and then it won't be any good at all.
 
I have yet to see that! I dont think anyone is using a air grease gun and emptying the tube of grease in the thing.
 
come on are you serious? Very easy to push those seals out if you give them too much. The seals in those bearings aren't tough by any means, very easy to pull them out of the groove.
 
there isnt anyone on this board that stupid to keep on pumping the grease in till you blow out the seal, a couple pumps(that means 2 by the way) every 1000 miles or so and the bearing last longer then the sled. Ya know the bearings seep grease by your seal so it does go somewhere after time.
 
ok my bad then. Just threw it out there as a word of caution so as to not cause a mess. Never said it wasn't a good idea, i've done the same thing to my viper and srx. Wasn't trying to start anything by it...
 
Drive axle bearing

Don't forget to tighten the two set screws that lock the collar to the shaft. If you do not the bearing will spin on the collar ad kill the shaft in short order.

Do this as the very last step, AFTER you install the chaincase gears if you take it apart.
