Type 2 CVT: Clutch Total Endplay Adjustment – Bearing Race Selection

IMPORTANT: The clutch total endplay (Figure 131) must always be adjusted when a new
sub-assembly is installed.


The Type 2 CVT uses the thrust bearing race thickness between the clutch drum
of clutch assembly and the oil pump cover (dummy cover) to adjust the total
endplay.
