Default Jackshaft Alignment Tool PN 2871296

Currently changing out track on 2007 Trail Touring Deluxe 550 Fan. Manual mentions using J A T PN2871296, and am having trouble finding one anywhere online. Don't want to enter in to this, do all the right things and find out I blew it by not following directions. Any help would be appreciated. Thanks.

not sure why you're needing a jackshaft tool when you're taking out the driveshaft to change the track...

You are correct 'Sir, went too far into reading the Manual, trying to cover the bases before I begin. Think I was in the deep end of the pool there for a minute. So am I to believe I stop at the drive shaft and avoid changing out the jackshaft bearings since I'm in this far ?

Some people avoid that. I even had a Polaris mechanic tell me not to replace the jackshaft bearings unless there was an obvious problem. If this were summer, I'd say to do them both at the same time. But, if you'd rather be riding, then skip the jackshaft for now and do it this summer.

I despise working on snowmobiles when there's snow on the ground and am 100% in favor of preventative maintenance when it comes to bearings (which are always one ride away from self destruction, in my opinion). One of my summer projects is to go back through the sleds and check all the bearings.

Edit: FWIW, I have never used one of those alignment tools, which is probably why my bearings are always one ride away from turning into cheese whiz. There are probably generic ones available on DennisKirk.com which will work just fine, if you want one.

Spoke with a Polaris Mechanic today and he says you can replace bearings or not, OEM or aftermarket they probably both originate in China. Sled has 1550 miles on it, if you never had this track issue you wouldn't consider bearings at all cause you'd never be tearing into it just for something to do. If the ones that are in it are smooth just switch out the track and be careful of the seals. The original bearings might be better than what you'd be replacing them with. Now that's just not how I'm inclined to do things but, if it all looks good we'll see. Sled always stored inside, very well maintained.

i have never changed the clutch side bearing as it doesn't get the load that the driveshaft does. If i were you, id pull the seal with a small pick and check it out and add some more low temp grease if needed. I'd be very surprised if the chain case side bearing is shot as well

Thanks Gentlemen, ordered track yesterday, did the tear down today, went smoother than I thought, will need to order a couple nuts and bolts, a gasket for the speedometer, and a cotter key for the chain case. Sweat equity but, less expensive. Everything inside bearings etc. like new, lucked out on this one so far, skid gets a good look over & I hope we're good. Definitely didn't need to go into the jackshaft, Thanks.
