classic motorcycle forum

Hi Guys, just joined the forum. I ride a Hinkley Bonneville on the road (in the summer!), but have just started tearing down a 1963 24RAS Greeves Silverstone for restoration, which has been lying in the corner of my garage since the 60s!

I need to remove the swing arm spindle. The metalastics on the arm rotate OK on the shaft, but the shaft will not budge.

On the left side of the shaft  a "D" shaped washer is welded on. Why not simply a round washer? Does the flat on the "D" signify orientation for a pin or key to prevent rotation?

Apparently there are no external bolts or pins, so should the spindle eventually slide out to the left?

Should it be possible to rotate the spindle as it is extracted (see "D" shaped washer)?

I'm going to try a few days with WD40 and then a bit of heat (being careful of the metalastics). Is there anything else I should know, or any tips that can be offered, as I don't want to hammer too hard and wreck something.

Last resort would be a hacksaw, but I'd rather avoid that if possible. Time is not a factor after 48 years!!

Thanks in advance for any assistance.
