Lubrication Instructions -- Continued
When AOAP analysis is not available and OE/HDO is used, change engine oil and filters at 150 hours or 1500 miles
(2413 km) of operation, or Semiannually (whichever comes first). If Engine Oil, Arctic (OEA) is used, change en-
gine oil and filters at 75 hours or 750 miles (1207 km) of operation (whichever comes first).
When AOAP analysis is not available, change transmission oil and filters at 150 hours or 1500 miles
(2413 km) of operation, or Semiannually (whichever comes first).
Always use the Expected Temperature Lubrication Table to determine seasonal lubrication requirements. When
changing engine and transmission oil due to seasonal requirements, always change the oil filters.
Sound maintenance practice dictates that AOAP is not a maintenance substitute, but is used as an effective mainte-
nance diagnostic tool. Therefore, if 12 months have elapsed since the last AOAP or seasonally directed oil and
filter change, the oil and filters will be changed.
WARNING
Clean parts with SOLVENT, DRY--CLEANING (P--D--680) (item 1, WP 0716 00).
Before you start your lube service, observe the following:
NEVER
a. Use wrong type lubricant.
b. Use too much lubricant.
ALWAYS
a. Clean grease fittings before lubrication.
b. Use these lubrication instructions as a guide.
c. Check for lubricant and fuel leaks along with daily services.
d. Check for clogged/unserviceable lubrication fitting if lubricant is not visible after attempting to service. If lubrica-
tion fitting is clogged/unserviceable, replace fitting and repeat service.
After water fording, you must lubricate.
Make sure vehicle is level when checking oil levels: If it isn’t, you’ll get incorrect readings on dipsticks and sight
gauges.
Oil filters shall be serviced/cleaned/changed as applicable, when:
a. They are known to be contaminated or clogged.
b. Service is recommended by AOAP laboratory analysis, or
c. At prescribed hardtime intervals.
