Bearings

[VectorGT07]

Hi guys, i've been reading a lot on here about repacking the Jack Shaft, and Drive bearings on these Yamahas. Do you think this is something I need to to now. I have an 07 Vector Gt, that only has 700 miles on it. I bought it new 2 seasons ago. I don't get out a lot, that's why I don't have too many miles on it. What to you guys think, as I need to get it ready for the summer.
Thanks

My 05 has almost 1600 on it, and I was curious also.

I would at least inspect the bearings on the clutch side of the sled, behind the secondary. It'll take you longer to remove the side panel than to do the inspection...probably a 15 minute job to at least get a peek. Remove clutch side panel/shroud, remove the belt, remove the secondary (keep the washers in the right order), and you're right there at the bearings. The bearing on the bottom by the speedo sensor is usually the one that is worst because it's more exposed/down closer to the snow - you will need to unbolt a metal guard off this bearing, and then carefully pry the bearing seal off with a dental pick or small screw driver. Have a look and see...these can easily be repacked in the sled without removal.

Shouldn't need to visually inspect the bearings. If there is no play in the shaft (grab it and give it a shake) and they are not making any noise when you turn it by hand, you should be able to carefully sneak into a corner of the seal with a grease needle.

That's the way I do it... 13,000 miles on my originals.
The grease needle works but you are better off flushing the water and any other crap out before adding new grease.
BTW the original grease in those bearings looks like Vaseline and you do need to get rid of that!

Thanks for the info and tips. I'll give it a shot, and get back to you guys.

read all threads regarding bearings, my chaincase bearings blew at 3000 miles

I changed all four of mine at 5000 miles and the only one that was bad was the lower bearing on the PTO side. The rest were good to go but I changed them anyway since I had the parts.
