Changing Front Axle Differential Case/Final Reduction Gear Case Oil - New Holland TC21D Operator's Manual

Changing the Front Axle Differential Case and
Final Reduction Gear Case Oil
NOTE: The front axle differential case and final
reduction gear case oil should be changed after
every 300 operating hours.
1. Place a suitable container beneath the oil plug.
With the oil at normal operating temperature,
drain the oil by removing the drain plug, 1, on the
standard FWD axle. After the oil has drained,
reinstall the drain plug and discard the used oil.
2. Remove the dipstick/filler plug, 3, on the
left-hand side of the axle housing. Fill the axle
with NH 134 hydraulic oil until the oil level is
between the full mark and the lower end of the
dipstick. Reinstall the dipstick/filler plug.
NOTE: Approximate fluid capacity for the differential
axle housing is 1 L (1.06 U.S. qts.).
NOTE: To obtain correct oil level reading, do not
screw dipstick into axle housing when checking oil
level.
3. Remove the drain plug, 4, from each final
reduction gear case. After the oil has drained,
reinstall each drain plug and discard the used oil.
Remove the filler plug, 5, from each final
reduction gear case and fill with NH 134 hydraulic
oil so that the oil level is at the bottom of the fill
port opening. Reinstall each filler plug.
NOTE: Approximate final reduction gear case fluid
capacity is 0.4 liter (0.38 U.S. qts.) per side.
