Axle undersizing

[erussell]

I have a 84 200es that has been going though some loving in the last few months. New Honda fenders, NOS speedo unit, etc. I have replaced about every bearing that I could find and I think all of them were original.
Well bad news for me. I replaced the rear bearings, well I was hoping that it would fix the slop in the rear axle. It helped but it was still sloppy, so I took the axle out and had the dealer check the tollerences. Well I guess it is time for a new axle and they are not cheap. Partsfish wants $248USD. The dealer (if they can still get one) wants about $300CAN, but they arn't sure on the price or if it is available.
The Honda dealer says I can't take it to a machine shop and grind it true and then use oversize bearings, because it would weaken it too much. But of course they want to sell a $300 axle. What have you guys done? I will pay it if I have to, but it will come from my sons quad fund and he won't be so understanding if he has to wait an extra month!

there is a shop around here that does metal spraying to build up metal shafts, maybe you should inquire about that ,,, it works great and will sovle your problem,,,,, alot cheaper too,,,,,,

may i ask how the axle got undersizerd or smaller?

[Mr. Richard]

if you run with bearings loose they tend to work on the axle and wobble them out,,,

[erussell]

Yeah, Kaseys right. It had the original bearings in there that were very worn. Slowly it rubs away at the axle, and in my case not evenly. I think I will see what I can do to the old axle and if anyone can add some weld, or metal spray and then grind it true.

A good machine shop can weld it and then turn it back down to the original size. just like they do to eng crank shafts.

Hey dads!
I will need all of the info like bearing inside diameter, and the size that the crank should be. I wonder if the Honda dealer will give that info up? I have a Clymer manual but it doen't have that much detail about stuff.

i would try loctite, they have a product called quik-metal that is made for this type of thing. if you have a local bearing distributor like "bearing distributors inc" go talk to them as they are a distributor for loctite. or try either of their web sites, they must have them.
i've had a couple of axles in the lathe on center and they are too tweaked alot of times to get it to run true enough for bearing tolerance work. the 250r lends itself to working the sprocket hub a little better because of the long splines for the axle nut. i was able to use the splines to turn the axle seal flange down and make a new sealing ring and press it on but most axles aren't flat enough so that you can chuck it.
the other question i would ask loctite is how to get that crap off if you want to change the bearings later
