SEE 050483 FOR FULL SERVICE KIT.

A METALASTIC TYPE BUSH THAT IS USED ON THE PRE COMMANDO SWINGING ARMS.  THIS TYPE OF BUSH ALLOWS ROTATION WITHOUT ANY WEAR AND IS USED EXTENSIVELY ON MANY TYPES OF SUSPENSION.  THE BASIC PRINCIPLE IS THAT THE OUTER SLEEVE IS AN INTERFERENCE FIT IN THE HOUSING (IN THIS CASE THE SWINGING ARM) AND THE INNER SLEEVE WHICH PROJECTS OUT AT BOTH ENDS IS LOCKED TO THE STATIONARY COMPONENT (THE FRAME( BY THE CLAMPING EFFECT OF THE SPINDLE.  THERE IS THEREFORE NO WEAR ON THE SPINDLE OR FRAME AS THERE SHOULD BE NO RELATIVE MOVEMENT.  TYPICALLY THE BUSHES HAVE A SPACER BETWEEN THEM (067716 FOR THE FEATHERBED).  THE PRE FEATHERBED SWINGING ARMS ARE SLIGHTLY NARROWER OR SHORTER BETWEEN THE FRAME RAILS AND DID USE A SHORTER BUSH ALTHOUGH BOTH THE EXTERNAL AND INTERNAL DIMENSIONS ARE THE SAME.  IT FOLLOWS THEREFORE THAT THESE BUSHES COULD WITH A DIFFERENT SPACER AND THROUGH STUD BE USED ON THE PRE FEATHERBEDS.
