1970 A65 rear wheel bearings
« on: 27 May, 2022, 21:29:32 »
Hi. My first post so hopefully I donít do anything wrong!
I am rebuilding a 1970 A65L. The bike was in Ďkit formí when I purchased it. It came with a QD crinkle rear hub. The main rear spindle is 11/16 inch in diameter. Iíve looked at all of the Ďusualí suppliers (e.g. Draganfly and Feked) that I know of but all I can find offered is bearing 65-5883 which I believe is for a 9/16 inch spindle. Can anyone please advise the number of the bearing I need for the hub with an 11/16 inch spindle. The outer diameter of the bearing is, I believe, 50.81mm). Iím sure that the hub is correct for the frame as the rear spindle adjuster slots in the swing arm are 11/16 inch wide.
Thanks very much
Regards
Tony

65 5883 aka RLS7 aka LJ7/8 is 7/8 inch id x 2 inch od x 9/16 wide is the correct bearing for the 1970 crinkle hub. Remember the spindle goes through the spindle sleeve, the bearings seats on the reduced diameter ends of the sleeve.

Below from the 1969/70 workshop manual.

The brake drum takes 65 2045 aka 6205 aka LJ25 which is 25mm id x 52 mm od x 15mm wide.

Thanks very much for clarifying that. I didnít realise that the inner bearing races bear against  the spacer tube in the hub. That solves the mystery.
Thanks again
