Time to gather up some more parts to replace my mainshaft bearing again. This time I got the Baker IPB bearing and hopefully this time I can find someone who has the IPB inner race removal tool so I can borrow it! Anyone on the central coast of cali got one I can rent?

 

you should just buy a box full of bearings you are going to need them, and renting the tool your better off buying one again your going to need it, my buddy after 4 times finally traded in for a newer bike (new) 2010

 

trade it in for an 06 5 speed.
Problem solved.

 

Were the heck do you rent the tool as it is for the 07+ 6 speeds. I don't think auto zone is going to carry it unless there is a huge demand for it?

 

I would check that mainshaft, bet its bent

 

Dont think it's bent. This is my second main shaft bearing but I only have 73,000 miles on it so if it was bent it would have failed much sooner. I replaced my first one at 43,000 miles. Its starting to leak and last time I thought it was just going to be a seal but the bearing had failed.

 

If you can't find a race puller to rent or you don't want to spend the money, there's another way. I cut my inner race off of the shaft. It takes about a half hour. You'll need a Dremel type tool and a carbide tipped cutter (around $10 at Home Depot) pictured below. You cut/grind a groove in the inner race lengthwise to the shaft. Don't cut all the way through to the shaft, leave a just enough material so you don't grind through and damage the shaft. When you've ground the slot the length of the race, take a chisel and stick it on the end of the race against the last remaining material of the groove and give it a whack. It will crack right along the groove. Depending on how much heat was generated from the bearings grinding on the race, it may be stuck on pretty good. If it won't come off easily, just grind another groove opposite the first one and do the same thing with the chisel - it will come off the shaft in two pieces. Be careful not to damage the seal in the inner primary case with the cutter. Also, don't push the inner race against the seal when you whack it with the chisel. Obviously take precautions to deal with all the metal shavings you'll be creating and wash everything out when you're done.

 

Thanks QehQeh. I've been a field heavy equipment mechanic for 10 years and thats how I removed the last one. I'm going to try and find the correct puller first and If I cant find one then I will try a small bearing splitter in conjunction with a t-bar puller. Last time I installed it I used anti-siese bieng that it is press fit.

 

sounded like it had failed rather quickly from your post, you're right, but still that brg usually lasts very long time, 100k easy

 

Here's a photo of the race after removal for anyone interested.
