OPERATION 25
CHANGE TRANSMISSION/REAR AXLE/HYD-
RAULIC OIL AND FILTERS
Prior to changing the oil, run the engine and operate
the hydraulic system until the oil is warm. Park the
tractor on level ground, lower the 3-point hitch and
stop the engine. Apply the parking brake and block
wheels on both sides.
WARNING
Be very careful to avoid contact with hot oil. If oil is
extremely hot, allow it to cool to a moderately warm
temperature before proceeding.
There are two drain plugs (1), for the oil reservoir, one
below the transmission and one below the rear axle.
To ensure the reservoir is completely drained, both
drain plugs should be removed using a hexagon key.
To change the oil:
1. Remove the drain plugs (1) Figure 76 and
completely drain all oil into a suitable container.
Dispose of the oil properly.
2. Re-install both drain plugs after the oil has
drained.
IMPORTANT: Perform Operation 19 (change
hydraulic and transmission filters) before refilling
with oil.
3. Remove the filler plug cap (1) Figure 77 and refill
with new oil.
4. Run the engine and operate the hydraulic
system. Fully raise the 3-point hitch.
5. Stop the engine and wait five minutes while
checking the system for leaks.
6. Check the oil level by means of the sight glass
(1). Add oil as required until the oil level is
between the 'MIN' and 'MAX' marks.
NOTE: Do not fill above the full mark.
