Digital Gauge “Zero” Procedure
The Depth Gauge needs to be set to “zero” before performing measurements in the
following service procedure.
IMPORTANT: This procedure MUST be performed before proceeding.
Measurement tools:
Gauge Block (straight bar)
Depth Gauge (Digital Vernier scale) with a datum level (accuracy: 0.01 mm)

Depth Gauge Calibration
To calibrate the Digital Depth Gauge J-50272:
a. Turn the Depth Gauge ON and set it to “mm” measurement.
b. Place the Depth Gauge’s datum level flush on top of the Gauge Block.
c. Carefully slide the depth marker down until it bottoms out on the Gauge Block.
d. With the depth marker bottomed out, press the “ZERO” switch.
The Depth Gauge’s display should now read 0.00 mm.
NOTE:
Push (extend) the depth marker to the gauge block to correctly zero.
Do not use the gauge block to push (retract) the depth marker up to the datum point.

Type 2 Thrust Bearing (with bearing race).
Type 1 CVT: Clutch Total Endplay Adjustment – Thrust Bearing Selection
IMPORTANT: The clutch total endplay (Figure 1G) must always be adjusted when a new
sub-assembly is installed.
The Type 1 CVT uses the thrust bearing thickness between the clutch drum of clutch
assembly and the dummy cover to adjust the total endplay.
Thrust Bearing Selection
There are eight (8) thicknesses of thrust bearing available for total endplay adjustment.

b. Choose the appropriate bearing from Table A below, based on A (eight different
thicknesses of thrust bearings are available).
