Remove the axle shafts as a whole as described in section 14.3.
Using a screwdriver, remove the seal from the bearing cover, placing a rag under the screwdriver to avoid damaging the surface of the cover, as shown in Fig. 226.
Fig. 226. Removing the seal from the main gear bearing cover. Position of the screwdriver tip when removing the seal.
1 - oil seal cover,
2 - oil seal.
Check the condition of the working surface on the inner end of the axle shaft and, if necessary, replace the axle shaft. The seals on the inner surface have oil-scraping screw grooves with different directions of turns. On the left axle shaft, the right direction (marked in red); on the right axle left direction (marked in green).
It is not allowed to change the places of the seals, because this will disrupt their operation. Before installation, it is necessary to compare the new seal with the one removed from the cover.
Press the new seal with sealant applied to the outer surface into the cover using a mandrel. The end surface of the seal, when installed correctly, should match the end of the bearing cover.
Install the axle shaft assembly with the spacer ring as described in section 14.3.
Place a new mounting ring on the end of the axle shaft. Check the axial clearance between the inner end of the axle shaft and the differential housing. The clearance should not be noticeable, but the mounting ring should rotate in the groove. If necessary, install a thicker or thinner mounting ring.
Fill the final drive housing with the prescribed oil up to the lower edge of the filler hole.
