A10 swingarm fitment
« on: 02 October, 2017, 03:58:50 »
Hi all, I am new to this game so bear with me if question is a bit basic.
I have a 1958 A10. New powder coated frame, new powder coated swing arm, new silentbloc bushes fitted. How Do I get swingarm to fit in frame when bush centres are too wide without damaging new powder coat. It has been suggested to me to file ends of bushes down but this seems to me to defeat the purpose of the silentbloc bushes.
Regards
Cactus

I have found that to remove and to refit the swinging arm it is necessary to tap it up one side and down the other side on the bush housing to twist it to allow removal and subsequent refitting.

It is necessarily tight to allow the inners to be clamped against the frame plates when the spindle nut is finally tightened.

Most of us have reduced the clearance because the commonly used powder coating is somewhat thicker than the original stove enamel finish.

On my A10 swinging arm the bushes protrude about 1/16 inch each side giving zero clearance when fitted and before tightening. I see some bushes are advertised as being 4 3/4 inch total length which seems to me a bit too long given that the dimension between frame plates is given as 9.373 - 9.383 inches. Just my opinion.

Be carerful filing the bush ends - there is often little clearance between and assembled swinging arm and the pillion footrest frame loop on the chain side and with filing you could reduce it to zero!.
