Speedo bearing

[Bluebullet]

Put new belt on and went for a short rip around the house in 30" of fresh powder couple of days ago and had the famous left foot wrap a tap a tap. May bee my new belt not being broke in or is my speedo bearing going bad. All looks well down there nothing obivious with the bearing, seal is intact and no shaft slop. I am going to put the old belt back on and try it 1st and see what it does. My sled was in a warm garage 45 - 50 degrees. I have a spare bearing that I removed from my RX1 when I changed a track a couple years ago that I repacked and kept in the sled just in case. I will take the current bearing seal off and inspect the balls when I get a chance anyway, do you think if I clean and repack I will be all right? I may just change it out anyway just to be sure? just asking ?
Thanks

It's easy to clean and repack it - so that's worth a try. The thing is you can't see the balls of the bearing due to the ring that's in there. My jack shaft bearing went dry last year but it was just squeaking like rubber rubbing on something no tapping, etc.

It is easy to replace by simply loosening your track tension so I would just put a new one in for peace of mind.

So can they be removed without taking the drive shaft out? Would you need any special tools to pop the bearing off? I was going to do my bearings this year and started with the jackshaft and couldn't get it off and I read that the chaincase might have to be taken apart which I didn't want to dig into right now. So the drive shaft bearing might be easier?
thanks,

The driveshaft bearing is much easier to replace than the jackshaft bearing. No need to pull the suspension or the driveshaft. Loosen your track tension, remove the speedo pick-up gear from the end of the driveshaft, remove the bearing cover plate, loosen the two set screws on the bearing collar inside of the tunnel, then slide the bearing off of the driveshaft by first pushing from inside of the tunnel. If it is really stuck on the driveshaft you may need to use some penetrating oil.

Put the old belt on, all good. New belt has been on the sled holder for about 3 years so must of been egg shaped and hard. I am going to repac the bearing and get a closer look on my next day off. Thanks all

Good to know thanks. BTW, I wonder would the new belt eventually conform to the correct shape and break-in?

It should. I have never had an issue with a belt that was stored in the belt holder even at very low temps.

I am sure it will conform and round out. Hard to even get the belt warm around the house plus the deep snow at the time. I will put the new belt back on when I head out to the trails and can get more of a normal belt breakin or use.
