IMPORTANT: For the initial filling of a new replacement front axle differential, the gearbox is filled with 600 ml oil! If oil is filled up to the lower edge of the oil filler opening, the gearbox would be overfilled and in rare individual cases oil could emerge from the ventilation opening on the front axle differential.
WARNING: Danger to life! SECURE ENGINE IN INSTALLATION POSITION to prevent it from falling down.
Necessary preliminary tasks:
IMPORTANT: Grip front axle differential firmly while releasing last bolt in order to avoid damage caused by the differential falling.
