Using excellent pictures. description of axle removal from FJR tech site, I have been pounding threaded side with hard block of wood/mallet. I can rotate with 14mm toolkit socket but will not slide out. Any other advice?

Scabs right, BFH. Or failing that, I bust out the metric sledges.

 
Robber, I think our two previous poster friends are being a might facetious....? :huh: :unsure:

A hammer is not your friend when working on your FJR.

Unless your axle is rusted in place -- (highly doubtful) -- it should unscrew and pull out with little effort.

Re-check your procedure... (and put away the hammer). :eek: :)

 
I loosen the axle nut all but 1 thread. BFH on the axle nut till I can't go any more. Remove the nut. Take a 3/8 extension, place it on the end of the axle and BFH to knock it out. When you put it back together, make sure you put some grease on the axle before reassembly.

You loosened the pinch bolt, right?

Also, try putting your foot under the tire and lift gently upwards with your toe to relieve some of the tension on the axle.

 
Remember: If at first you don't succeed, force it. If it breaks, it needed replacing anyway.
And...when all else fails, get a bigger hammer.

Now, this was facetious. I was serious the first time. The brass drift will prevent damage to threads, the BFH will motivate it. ;)

Counting on, of course, that the pinch bolt is loose. My old one always needed a little motivation. Once it moved any, then it came on out easily.

Pinch Bolt was loosened. I been beating the hell out of the axle with no sliding movement. It does spin though. I will try later with heavier hammer on piece of hardwood.

Thanks for advice,

Rob

Wow...the axle will spin, but it won't come out by beating the hell out of it...and the pinch bolt is loose? Really? Good luck with that.

 
With the axle nut off and the pinch bolt loose, push on the threaded end while you turn the other end with a wrench. Turn in the direction you would to loosen it. It should screw itself out, even though it is not actually threaded into anything. You can use a block or wood or leather glove to protect your hand as you push the threaded end. If you need to hit it with a big hammer then you really could break something that will be expensive to replace.

Make sure you have the rear brake caliper pivot bolt removed as well, this could be causing a bind.

 
The axle will normally pull out by hand after being tapped in flush with the left side using a block of wood. Not hammered, just tapped. The axle should turn by hand using the nut on the right side. There COULD be a bearing locked up that has spun on the axle creating a step. In that case, it still should come through by having someone tap with a wood block on the left side while another person turns the nut on the right side. A "place" should be found that will allow the axle to come through. It that still won't work, there is something really weird going on. A bad case of rust on the axle could cause this. The axle would move until it hit the rust area and then jam in the inner race of the wheel bearing. The axle would still turn since the inner race would still turn just fine, but the axle would not pull out of the wheel because it is firmly stuck in the inner race of the bearing. I have never seen a MC axle in this shape unless the axle had been in there forever and the seals had failed at some point...still it is a possibility. If it is, then some Liquid Wrench and tapping the axle to the right, then to the left, then more liquid wrench, then more right and left, and so on until the axle came out.

If you use a BMFH, then it is going to be really expensive to put it all back together. Some common sense and patience is the way to go.

Free advice....worth what you pay for it...YMMV.

Ed :rolleyes:

 
Also, of course, have the wheel supported from below to take weight/drag off the axle as you remove it. If it will turn it should come out with a little direct force from a hammer. You can protect the threads with a piece of wood and with the nut on the axle. You might squirt a little oil in the lower side of the axle/swingarm junction on the right side.

But if you support the wheel and unload the axle it should come out fairly easy.

 
Yuck! Axle spins freely but won't slide out? Rear caliper arm pivot bolt removed like somebody already asked?

Maaaayyyybe pinch bolt was never tightened and the axle has hammered an edge on the swingarm hole?

Maaaayyyybe it's been in there a long time with no grease and has welded itself to the steel spacer between the hub and pumpkin drive?

I would go for some WD-40, a brass drift, BFH and patience, all at the same time!

Holding up part of the tire weight with some folded newspapers or other shim material will make it easier for the axle to slide out.

I'm guessing you've beat a lip on the end of the threaded end of the axle. Press the axle back to where you started and see if you can thread the nut back on. If not, look close, file/grind off the burr you've created, press the axle out, and if the burr sits under where the nut covers then buy a new axle.

It shouldn't be this hard.
