    Gap between rear brake and wheel

    Hey all,

    I'm just putting this 1982 GL500 back together and I've come across kind of a weird gap between the lip of the rear wheel and the the lip of the rear brake cover/holder. The center hub of the cover just rests on the center of the wheel bearing which means there's a fair ~1/8" cap between the wheel and the cover. Obviously I don't want the touching but it seems as though dirty or water will get into the rear drum and just tear up the brakes. Has anyone else noticed this or am I missing something?

    Is your axle pulled in flush with the frame on the left, or hanging out by that same 1/8 of an inch.

    I think I have the same weird gap, and if I understand correctly, the axle is also protruding slightly from the frame. I'm talking mm here... (I don't understand inches..lol)

    will try and post a pic just now..

    Ramprat..are you saying, that if you loosen everything around the axle..both sides..(or just on the side of the brake?) and hit the axle from the Brake's side ..back in, to be flush with the frame, then the gap at the brake drum will also be gone? Is that the correct fix?

    If not only the axle gripping nuts..what else will I have to loosen to fix this?

    Rather than hit it with a hammer, undo the frames pinch bolt on the left side and remove the axle split pin on the right.

    On the left side of the axle is a flat to take a 17 mm spanner.

    Hold the axle by the flat and torque the axle nut. This should pull everything into line.

    Do as I posted above Speedster. Zeig heil!

    It is hung up on the O ring. This is where they stop on one.

    Use the axle nut to 'press' it through.

    Don't use excessive force if it doesn't move ..... but it probably will.

    It might pay to loosen the final drive nuts {3 of} first and retorque them after.

    There are two O rings that keep the grease in the final drive.

    Often people will push or knock the axle in until it contacts one of these O rings. Since the axle seems reluctant to move further they figure this is as far as the axle goes in and then tighten the pinch nut, followed by the axle.

    The axle should always be drawn in by its nut and then the pinch nut tightened . In that order.
