Title: 1961 A10 S/Rocket. Rear wheel binding
Post by: BARNFIELD on 15 September, 2017, 17:07:34
Removed rear wheel/drive sprocket completely to free sticking brake plate cam. Yes, i now know i could have left the sprocket ass. in situ. Freed up the cam spindle, deglazed the shoes and drum and refitted the wheel. After tightening the wheel spindle/nut the wheel is now binding and requires some effort to turn by hand. The shoes are not binding. Wheel turns freely when slackened off. Noticed a spindle-sized washer on workstand which i fitted next to the distance piece "cotton reel" on outside of the brake plate. Wondering if this should be fitted inboard of brake plate. Can anyone help please. Thanks Greg

This cross section of rear hub may help. Presuming you did not remove the bearing then the washer may be the one which goes under the spindle head. Certainly no washer between cotton reel and brake plate of swinging arm and not washer between brake late and bearing.

If this does not solve issue please post a photo.

Does that small distance washer fit between the speedo drive and the S/arm like on the older models ?

A10 speedo drive is taken from the gearbox.

Hi Julian, thanks for providing a cross section line drawing of the rear hub. The bearings were not removed and the washer at the spindle head is still in place. Have studied the drawing and identified all the parts, and as you state, there is no washer shown inboard of the brake plate. Have removed the wheel again and refitted but the problem remains. The "spare" washer is similar in size to the one at the spindle head and have no idea where it was dislodged from.
