7-26 How to Perform Planned Maintenance
Sump Tank Breather Maintenance and Inspection
Remove the sump tank fill cap/breather and inspect for excessive
(obvious) contamination and damage. Replace the fill cap/breather,
per recommended PM schedule or as required by operating
conditions.
Transmission Fluid Check
Before checking, run the engine until
the unit is at operating temperature.
This is important since transmission
oil temperature should be 65°C~120°C
(150°F~250°F), the engine should
also be at operating temperature.
Block the drive wheels.
With the engine operating at idle the
transmission in NEUTRAL and the drive wheels
blocked, check the fluid on the dipstick. Fill, if
necessary, to the FULL mark on the dipstick,
using CLARK transmission fluid (Mobil 424, US
market). If unable to determine actual oil
temperature, use this alternate check method:
With the unit cold, start and run the engine at idle
for 30 seconds then check the level and fill only to
the ADD mark.
Check the planned maintenance interval (operating hours)
or the condition of the oil to determine if the transmission
fluid needs to be changed.
Drive Axle fluid check
