Check

PERFORMANCE ORDER

Check a condition of all details of differential and, if necessary, replace them.

Installation of the conducted gear wheel

PERFORMANCE ORDER

Examine a gear wreath of the conducted gear wheel on lack of wear and cracks. If it was carried out it is replaced details, adjust a preliminary tightness of the bearing.

Installation of bearings

PERFORMANCE ORDER

1. Check the bearing for absence of damage and smoothness of rotation. If the bearing was removed, replace rings of bearings and adjust a preliminary tightness of the bearing.

2. Install by special OK900 175 AA1 adaptation the new bearing from the conducted gear wheel.
3. Install the speedometer drive.
4. Install by special OK900 175 AA1 adaptation the new bearing from the opposite conducted gear wheel.
5. Establish a new cylindrical pin as shown in the drawing to record an axis of satellites.

Check of a side play between a semi-axial gear wheel and the satellite

PERFORMANCE ORDER
1. Establish the left and right power shafts in differential.
2. Install power shafts in V-shaped blocks.

3. Measure by the indicator of hour type a side play.

Side play: 0-0,1 mm

4. If the side play exceeds admissible limits, replace the damaged and worn-out details.
