## Discrepancy

BUSHING PN 105-13241.02 FOUND TO BE PRESSED FROM THE OUTSIDE TOWARD THE INSIDE INTO FORK LINK ASSY PN 105-13241, SN 3181, INSTEAD OF FROM THE INSIDE TOWARD THE OUTSIDE AS SHOWN IN IPC.  A CORRECT ASSEMBLY WOULD CAUSE THE BALL BEARING PN MS27649-5 OF THE DRIVE LINK ASSY TO CONTACT THE BUSHING PN 105-13241.02 OF THE FORK LINK ASSY, BUT THE MIS-ASSY CAUSED THE CASTINGS OF THE FORK LINK ASSY AND THE DRIVE LINK ASSY TO CONTACT EACH OTHER WHEREBY CAUSING EXCESSIVE WEAR TO THE LINK CASTINGS.
