Drive axles, checking oil level
1 Park the machine in service position and let it stand for 2 minutes.
2 Remove the combined level and filler plug (A).
The oil level should be up to the hole.
The hub reductions have a common oil space with the final drive
(differential carrier assembly), and the oil level shall only be
checked by the level and filler plug on the final drive.

Drive axle, tractor unit: right side, at the front
Front bogie axle: left side, at the back
Rear bogie axle: right side, at the back

housing as well as the plug (D) from the hub reductions.
3 Reinstall plug (B) and (D).
4 Adjust the wheel so that the plug (D) ends up in position (C).
