Filling and Adjusting
- Gear oil temperature: Approximately 20 °C (68 °F) (room temperature).
-- Place the :SMN372500 under the transmission.
Danger of eye injury.
- Wear protective eyewear.
-- Remove the drain plug -arrow A- from the center differential housing.
-- Install the :VAS6617/6 with the :VAS6617/2 in the inspection and fill hole in the transfer case hand-tight.
-- Connect the :VAS6617 and fill the transfer case with approximately 1.0 liter (1.05 quarts) of gear oil.
- Transmission fluid. Refer to the parts information.
-- Wait five minutes.
The inside of the transfer case is divided into several oil chambers. The chambers must be filled equally.
A waiting time of at least 5 minutes is required so that the internal oil level between the center differential and oil fill space can equalize.
-- Remove the :VAS6617/6 from the transmission and let any extra oil drain out.
- Specified value: The level is correct when the transmission fluid comes up to the bottom edge of oil filler hole. Fill the gear oil once more if necessary.
-- Tighten the new drain plug -arrow A- for the center differential housing.
It is not necessary to check the oil level again at this stage.
