I own a 2000 Honda 450 S Foreman. My rearend was slipping so I disassembled it and found that the axle splines at the ring gear were worn down beyond use. Honda wants too much money for me so I was trying to think of a way to salvage my rearend. I was thinking about welding the ring gear sleeve to the axle shaft or having a machine shop put a keyway in it. Please help with any experience you may have. Thanks.

Get machine shop work done aint cheap either. There are places that dismantle and sell atv parts, used. Theres also ebay. Tried those?

 

Umm i think it needs to slide there or it will bind as the axle moves up and down. .



It should be fine to weld it unless it needs to give. Can you see any wear on the shaft that looks like the ring gear had to move up and down it?

I would reassemble and check to see if it needs to give. Tac weld the ring gear to it and and check the action if it binds and pops the weld then i wouldn't put a solid weld on it. You may brake something up in the engine.

 

I have suggested having customers do the key way option on old Big Red three wheelere, but not on any newer quads.
They have had success, but a few didn't get the keyway straight, or the axle was so worn that it would not center, causing the pinion to give out.
Welding would probably get the same result, from warping the axle and not having the ring gear centered. It would go around in an egg shape motion instead of circular motion.
I realize it is expensive to fix it right, but in the long run, it will probably be cheaper because if the pinion wears funny, it can and will require the complete differential case assembly to be replaced.

Not demanding how you repair the situation, mearly suggesting you do it the right way the first time.
Now if it was a Rancher, I have an extra set of gears and an axle laying around, that I would give you a great deal on...
