Clutch Total Endplay Adjustment – Thrust Bearing Selection
IMPORTANT: Using thrust bearings, the clutch total endplay (Figure 110) must always be
adjusted between the clutch drum and the dummy cover when a new sub-assembly is
installed.
There are eight (8) thicknesses of thrust bearings available for total endplay adjustment.
For additional information, see video # 547: “CVT Belt and Pulley Replacement”
and fast forward to minute marker 13:22. This video is located under the TECH

b. Choose the appropriate bearing from Table A below, based on the Total Endplay (A)
calculated on the previous page (eight thicknesses of thrust bearings are available).
Example: If A = 4.3 mm, it falls between the lower and upper clearances for bearing
thickness 3.93 mm.
Refer to the THRUST BEARINGS table on page 90 for Thrust Bearing part
