TO REMOVE ROLLER AND PIN SETS REMOVE PART#3, CLAMP, FROM PART #2, SHANK, AND DRIVE PIN OUT WITH ROD SMALLER THAN PIN DIAMETER.  PLACE BUSHING UNDER ROLL WITH HOLE DIAMETER SLIGHTLY LARGER THAN DIAMETER OF HEAD OF PIN.

TO INSTALL NEW ROLLERS AND PINS MERELY DRIVE PIN WITH ROLLER ON IT BACK INTO CLAMP, OR SHANK, LEAVING IT SLIGHTLY LOOSE SO THAT ROLL WILL REVOLVE FREELY.
