OPERATION 45
Change the Differential Oil
To change the differential oil, operate the tractor
a sufficient amount of time to warm up the oil in
the differentials. Loosen the check plug, 1, and
remove the drain plug, 2, to allow the oil to drain
completely from the differential housings. Once
all the oil is removed, replace the drain plug and
tighten it to 74 N⋅m (55 ft. lbs.). Make sure the
sealing surface on the plug is in good condition.
Refill the differentials through the check plug to
the proper level as indicated by the sight gauge,
3.
Buhler Versatile recommends that 85W140 GL5
oil be used in temperatures above 0°C(32°F) or
80W90 GL5 in temperatures below 0°C(32°F).
This oil is available from your Buhler Versatile
dealer.
NOTE: Oil will flow from the differential to the
planetary hubs. Change the oil with the
tractor on a level surface and allow the
differential and planetary hub oil to level out.
