1980 GS 750E Axle removal

1980 GS 750E Axle removal. I removed the rear wheel to clean it up and do 530 conversion etc. The axle will not slide out. The caliper bracket seems stuck on it , I don't know . Maybe I'm just missing something simple.

It’s covered pretty thoroughly in the Factory Service manual, start on pg. 7-33 with the parts diagram. If you’ve managed to loosen the castle nut, loosen the tensioners both sides, pushed the whole work forward to facilitate moving the chain aside, moved the whole works out from under the bike, all you should have to do is remove the castle nut and pull everything apart. Taking pictures before you do helps get things put back together again.

I suppose axle could be corroded to bearing inner ring? Some LIGHT mallet action may be in order, along with your favorite penetrating oil.

Put the nut back on it so it is level with the end of the axle & then give a whack with a dead blow hammer (or if you don't have that use a lump of wood & a club hammer). It will shock it loose. You can then take the nut off & tap it through. It's easier to move the axle if you can support the weight of the wheel as you do it.

In addition to the good advice above, especially looking at diagrams I always have good results with heat (maybe 300F) with a gun, then a cool cycles or two with some penetrant, That's a whole other thread but PB Blaster does the job for me. Tap tap tap after giving it heat, and have patience. I have a hard time remembering when this hasn't worked but that could be senility getting to me. If it is aluminum surrounding steel the heat will work very easily. If all steel parts are bonding I sometimes heat it all up and put an ice cube or 3 on the inner part to shrink it down. Hasn't beat me yet. Well not that I can remember anyway!

Thanks for the tips. Wheel is off bike, manual just states remove castle and pull axle out. Will try above mentioned tips etc. Wheel spins fine on axle. Seems stuck on brake bracket.

Possible that someone has used the end of the axle to line up the swingarm & brake bracket by bashing it through with a big hammer...... Can create a lip in the aluminum of the brake bracket making the hole diameter smaller. That or some dirt trapped inside. I expect once you get it out it will be obvious what it was.
