COLD CHECK:
•
The only purpose of the COLD CHECK is to determine if the transmission has
enough oil to be safely operated until a HOT CHECK can be made.
•
Park the vehicle on a level surface and apply the brake as specified above.
•
Run the engine for at least ONE minute. Shift to DRIVE (D) and then to
REVERSE (R), then shift to NEUTRAL (N) and allow the engine to idle.
•
After wiping the dipstick clean, check the oil level. If the oil level is within the
COLD RUN band, the level is satisfactory until the oil is hot enough to perform
a HOT RUN check. If the level is not within the COLD RUN band, add or drain
as necessary to bring the level to within the COLD RUN band.
HOT CHECK:
•
Operate the transmission in DRIVE range until normal TRANSMISSION
operating temperature is reached. (140-220
°
F)
•
Park on a level surface, shift to NEUTRAL (N), apply the parking brake, chock
wheels and allow the engine to idle.
•
After wiping the dipstick clean, check the oil level. Safe operating level is
anywhere within the HOT RUN band on the dipstick.
•
If the level is not within this band, add or drain as necessary to bring the
level to within the HOT RUN band.
POWER STEERING:
Use Dexron III. Power steering fluid can be checked only when cab is raised.
Remove the cap from the power steering reservoir and check the dipstick. If
necessary, fill until the proper level is obtained.
FRONT AXLE HUBS:
Check for presence and level of 90 Weight gear oil lubricant in each front wheel
hub. If lubricant is not visible or is low, obtain a work order. There is a strap
across the fill plug which prevents filling by field personnel.
COOLANT:
The cooling system uses a 50/50 mixture of ethylene glycol antifreeze and water.
The system holds about 55.5 U.S. Quarts. Check coolant bottle as shown in
Figure 1
for proper level. The radiator has a sight glass which is visible only
with the cab fully tilted and the radiator cap is accessible only with the cab tilted.
Wait until the engine has cooled if it becomes necessary to remove the radiator
cap to add coolant.
