Two circuits carry out the functions. One circuit carries out
transmission functions, the other carries out steering and
auxiliary functions.

2. Remove the drain plugs (Fig. 19) and the filler cap (Fig.

correct level with an approved oil.
NOTE: Allow time for the oil to settle in the rear axle

the high pressure filter element located on the right-hand
