Bearing nehind the Secondary clutch

[03rx1mn]

My question is on a 03 RX1. I had a bearing failure on the bearing which goes behind the secondary. Bought the sled used and the bearing was bad. I upgraded to 05 parts. Over the weekend he blew the belt and noticed the play in the bearing area. Limped it back to the cabin and tore it down. Icould not get the bearing out of the bulkhead with out special tool. Should it be a tight fit or slide in like a speedo side bearing? It has a snap ring to retain it. I was unable to get a breakdown of the picture on Yamahas parts site. It seems like a strange design. It has a split sleeve which slides over the shaft and through the bearing. There is a nut on the other side. What keeps the sleeve from pulling through or the nut from backing out. How does the washer stack up between the clutch and bearing go? Trip is over and sled is 500 miles away and I would like to know how this works and how long this bearing should last.

Bearing has a tapered inner sleeve that matches the taper on the collar and the collar is held in by a nut on the other side of the bearing. It sounds like you have got that apart but want to know how to get the bearing out? It will be hard to get out but heat will help if you apply it to the area around the bearing, otherwise you have to take the chaincase apart and slide the jackshaft out. There is a thread on here from somebody who did it, try a search. Some people have even tack welded a puller to the bearing to get it out. Bearing life will depend on whether they are installed properly and lubricated every season. They should last for many seasons and thousands of miles if treated well. This is the tool that I made out of a 1" nut for removing the collar.

Thank you for that Help. I appreciate it.

i believe there is a snapring that holds that bearing in place, if its not there it should be.

How do you properly lube that bearing and while we're at it the speedo bearing as well?? On my Polaris 800 it had zirc fittings but I dont see any obvious grease points. This is my first Yammy I bought it in Nov. did all my pre-season stuff (greasing, shimming, oil / filter change) but I couldnt figure out how to grease the clutch side bearings. Also I assume the chaincase drive and jackshaft bearings are greased by the chaincase oil (like polaris?)

THanks!

AWESOME, that was exactly the info I needed! Thanks

Oh, as far as the bearings on the chaincase side.. they are greased by the oil sloshing around in the chaincase? yes?

Thanks
