The hydraulic system should be checked periodically for:
● Overheating
● Abnormal
noise
● Maintaining a clean, sufficient, quantity of hydraulic oil of the proper grade.
● Keeping all connections sufficiently tight to prevent oil leakage and air from entering the system.
● Changing the hydraulic system oil filter at the frequency recommended by the filter manufacturer.
IMPORTANT - THE LOAD HOLDING ABILITY OF THE LOAD HOLDING BRAKE SHOULD BE TESTED
ON A PERIODIC BASIS.
6.02 GEARBOX LUBRICATION
- An ongoing routine for assuring proper lubrication should be a part of
the overall maintenance program.
The gearbox oil reservoir must be checked and maintained every 75 hours of operation or every 3 months. To
check for the proper oil level, the truck must on level ground. Remove the oil level plug on the side of the gearbox.
A small amount of oil may drip from the oil level hole. If no oil
is visible, remove the oil fill plug/breather on top of the gear
box and add 80W140 oil until the oil level reaches the oil level
hole. Do not overfill! Screw the level plug and filler plug back
into the gearbox.
The gearbox oil should be completely drained and filled with
new oil every 1000 hours of operation or at least every other
year. The drain plug is located on the underside of the gear-
box. To drain the gearbox, remove the oil drain plug and
remove the filler plug in the gearbox cover. After the gearbox is
completely drained, reinstall the oil drain plug. Add three (3) U.S.
Quarts (2,8 l) of fresh 80W140 oil as described above and reinstall
filler and level plugs.
SAFETY BRAKE LUBRICATION - The brake housing must be checked and maintained every 75 hours of
operation or every 3 months. To check for the proper fluid level, the truck must be on level ground. Remove the
fluid level plug on the cover of the brake. A small amount of fluid may drip from the fluid level hole. If no fluid is
visible, remove the fluid fill plug on the cover and add automatic transmission fluid (Conoco Phillips Super ATF or
equivalent) until the fluid level reaches the fluid level hole. Do not overfill. Screw the fluid level plug and fluid fill
plug back into the brake cover.
The brake should be completely drained and filled with new automatic transmission fluid (Conoco Phillips Super
ATF or equivalent) every 1000 hours of operation or every other year. The drain plug is located on the lower por-
tion the brake cover. To drain the brake, remove the fluid drain plug, the fluid level plug and the fluid fill plug. Af-
ter the brake is completely drained, reinstall the fluid drain plug. Add new automatic transmission fluid until the
fluid level reaches the fluid level hole. Do not overfill. Screw the fluid level plug and fluid fill plug back into the
brake cover.
The (2) grease fittings on the gear box must be maintained every 75 hours of operation or every 3 months with an
EP type chassis grease.
