METHOD FOR CHECKING OIL LEVEL IN TRANSFER CASE AND ADDING OIL

• Apply the parking brake and fix the front and rear frames by using the frame lock bar.
• Immediately after the engine is stopped, parts and oil are still very hot. Wait for the temperature to
go down, and then start the work.
If ooze of oil is recognized on the transfer case, perform the checks.
1.
Start the engine.
2.
Perform the warm-up operation of the transfer.
After finishing the warm-up operation, keep running the engine at low idle for 5 minutes or longer.
REMARK
The completion of the warm-up operation of the transfer means that the oil temperature of the transfer is
warmed to approximately 40 °C to 60 °C. As a reference, after 30 to 40 minutes traveling, the machine rea-
ches almost this state usually.
When the ambient temperature is low (0 °C or less), perform the warm-up operation of the transfer by trav-
eling approximately 1 hour as a reference.
