Note. Adjust only when bearings are replaced
Install output shaft in clutch housing with bearings and pre-adjustment ring B. Vi. 1161 or similar 1.60 mm thick ring (large outdoor 0).
Install crankcase.
Install and torque-tighten the box connector bolts.
Install the dial indicator bracket plate B. Vi. 1161 (or similar) on the tripod body mounts.
Fit special bushing B. Vi. 1527-A and bolt C.
Install a pointer type indicator with a magnetic base.
Turn the output shaft several times to ensure that the bearings are in place.
Set zero on the indicator scale.
Using two screwdrivers as levers, pull up the output shaft.
Read the pointer type indicator.
Repeat these operations several times in the same sequence.
Determine the average value of the obtained values.
Calculate the thickness of the preload ring using the following calculation formula: prescribed value + thickness of the preload ring + average of the needle gauge = thickness of the preload ring.
Example (values in mm): prescribed value 0.26 + thickness of pre-adjustment ring 0.49 + average value of pointer indicator 1.60 = 2.35.
Note. A set of shims ranging in thickness from 2.15 mm to 2.43 mm in 0.04 mm increments is supplied as a replacement.
