Note: Adjust only if bearings are replaced.
Install the primary shaft together with the bearings and the pre-adjustment ring (B. Vi. 1161) with a thickness of 0.62 mm (small outside diameter).
Install the differential housing, install and tighten the gearbox connector bolts and the pointer indicator bracket plate (B.Vi.1161) onto the tripod housing mounts.
Install:
- bushing (B.Vi.1527) A;
- support ring B;
- gear ring C;
- nut tightened to end D (Fig. 3.91).
Fig. 3.91. Installing the adjusting sleeve, rings and nut
Fig. 3.92. Installing the pointer indicator
Install a pointer-type indicator with a magnetic support (Fig. 3.92).
Rotate the input shaft several times to seat the bearings.
Set the indicator scale to zero.
Using two screwdrivers as levers, pull up on the input shaft.
Read the readings on the pointer type indicator.
Repeat these operations several times in the same sequence.
Determine the average value of the obtained values.
Calculate the thickness for the pre-tension adjustment ring using the following calculation formula: thickness of the pre-tension adjustment ring + average value of the dial gauge readings – 0.02 (this value must be subtracted to ensure a minimum gap) = thickness of the adjustment ring.
Example (values in mm): thickness of the ring for preliminary adjustment 0.62 + average value of the readings of the pointer-type indicator 0.50–0.02 (this value must be subtracted to ensure a minimum gap) = thickness of the adjustment ring 1.10.
Note: A set of adjustment rings with a thickness of 0.86 - 1.30 mm with a pitch of 0.04 mm is supplied as a replacement.
