I was riding my sled down a groomed trail for about 20 miles and all of a sudden at approximately 30 miles per hour I heard a loud noise and the sled slowed to a stop. The driveshaft was broke on the right just next to where it enters the chaincase. I looked on this forum and it seems to be a problem. Of course I talked to a dealer and they have never heard of it. I was lucky and bought a used shaft and installed it. But I would not of installed it if I knew there was a problem. Anyone know of this and a fix so it does not leave me stranded again.

I just finished doing the same job at 8400 km. The jack shaft bearing is the cause. Once the bearing goes, it stresses the shaft near the chain case. Because the chain case has 2 bearings (inner and outer), something has to give. The shaft is hollow. I did the repair myself and still have 700.00 into it with new belt and did all the chaincase bearings as well. Every one on here recomends keeping new grease in the jack shaft bearing. I believe they are correct. Pop the seal and clean and grease it annually. Good Luck.
Are you guys talking the same shaft ?
Windsorsledder souded like he was refering to the bottom/speedo one. If it is... then i hear some RXs & APEXs broken drive shaft. Clean cut close to chaincase. First time i hear of RS machine.
As for jackshaft (clutch/top), there was some problem on RS chassis at first (2005) but a replacement (recall) fixed a wrong bering journal taper (or some like this) and since.. never heard of anything.

Windsorsledder here. I have 14000kms (8400 miles)on it. I am talking about the driveshaft, the one at the bottom and not the jackshaft. Also to the guy from Walkerton this happened in Chesley on Jan 12th. I bought a used shaft from Snowline, it was from a 2004 Warrior. Hopefully no other problems.
that is why i had my bearing replaced under my YES warrenty this year!!!! that seal can only be taken out so many times before it will not go back in properly...matter of fact is it is damaged the first time it is taken out to grease those bearings. wish yamaha would put a housed bearing and grease zerk there like i had on my old polaris'...

Hey Snofisher, I did not have a bad bearing just the driveshaft broke.

Any chance you had ice buildup in the tunnel that came loose and couldn't fit between the rad and the front of the track?

There was a good size piece of ice but it was between the track where the adjuster is and there was no noise in the suspension when it let go. I just hope this does not become an issue on the Vectors.
