Clutch Total Endplay Adjustment – Thrust Bearing Selection
IMPORTANT: The clutch total endplay (Figure 1G) must always be adjusted between the
clutch drum and the dummy cover when a new sub-assembly is installed and is adjusted
with thrust bearing thickness.
There are eight (8) thicknesses of thrust bearing available for total endplay adjustment.
For additional information, see video # 547: “CVT Belt and Pulley Replacement”

Please print this page and
attach it to the repair order.
b. Choose the appropriate bearing from the table below, based on A (eight different
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 PARTS INFORMATION for Thrust Bearing part numbers by thickness.
c. Measure and confirm that the selected thrust bearing is the correct thickness before
installing (Figure 9G).
