(3)
Remove six screws (51) and lockwashers (52) from each side plate cover (50) and remove both side plate

on the clamping screws carefully, until spring assembly (97) is relaxed or fully extended.
WARNING
When the four clamping screws are loosened, stationary driven varidisc assembly (100) may have
a tendency to slide back on input shaft (98) because of spring tension; therefore, ascertain that the
varibelt is at the outermost position of the stationary driven varidisc assembly to relieve the spring
tension.
(6)
Loosen the four clamping screws on the split hub of stationary driven varidisc assembly (100) completely,
and slide the stationary driven varidisc assembly off input shaft (98).
(7)
Reverse the procedures of steps (1) through (6) to install the replacement stationary driven varidisc
assembly.
