rear axle moves

[rtcc]

Hey guys,

 

I have never taken apart the axle or carrier on this thing, but recently my axle moves about an 1/8th of an inch in the seam next to the brake rotor. It does it when I move the bike side to side.

 

Is that just the bearings?

 

I want to replace it but Im not sure how hard of a job this will be.

 

Is it worth doing and putting the stock axle back in?

nNevermind it was the lock nuts.

 

but how do I need to tighten them? When I tighten them all the way to the right the axle doesnt want to move until I loosen them again.

ya you need to put new bearings in, all you have to do is get the old ones out with a hammer and a drift/punch, and to put the new ones in you take the new bearings,put them in the freezer and heat the carrier up (on the grill or oven or torch) and use a 2x4 and a hammer to put the bearings back in, make sure you put it in straight, you will have to let it cool down before you put the new seals in so they dont melt, and the seals should be flush with the outside of the carrier, i usually put grease inside the seal to help keep water out so the bearings last longer, and ya you can put the stock axle back in, this is any easy job to do

you can buy a wrench that a torque wrench will fit onto and you torque it to spec, i made one with 2 1/4 pieces of steel, welded them together, cut it so it would fit the lock nut (with bandsaw) and then welded 1/2 inch drive socket to it so i could use a torque wrench on it

make sure you get it tight because bad things can happen if they come loose

hope this helps

thanks man,

 

but on the lock nuts which way do I tighten them? all the way to the right? or do they like meet in the middle or something? I tightened the right one as tight as it would go and then snugged the left one against it but my bike wouldnt even roll when I pushed it. just not sure what to do.

 

thanks

there is actually a different torque spec for each one the inside one cant be to tight could cause problems, the outter one is going to be tighter to hlod them both in place. Do you have a service manual?

[rtcc]

I just have the yamaha shop manual. It doesnt explain it that well but by the pictures it shows that they need to be tightened to the left, not against the carrier.

This is an easy job... but a time consuming one.

 

Take both tires and hubs off. Then loosen both axle locknuts towards the left. Pop the masterlink off the chain and then take chain off sprocket.

 

Then the sprocket hub slides off to the left. Brake caliper on the back comes off the disc. Take it off and let it on the swinger or just let it hang.

 

Then tap the axle out towards the right if looking from the rear. Then take the carrier off to put new bearings in.

 

Note: If you never took the axle out, it might be hard to come out. Get a piece of woods, put it against the left rear axle end and give it a good whack with a buddy holding the bike.

 

New bearing are always good to have in there. Also, try and grease them as much as possible, and if you really want it to be easy, install a grease zirk on that carrier. That will make life alot easier for you greasing it.

 

But definately replace those bearings. Use the above methods, they all work.

 

Good luck
