LUBRICATION INSTRUCTIONS CONTINUED
2. This lubrication instruction is for Field Maintenance. Lube intervals (on-condition or hardtime) are based on
normal operation. Lube more during constant use, and less during inactive periods. Use correct grade of
lubricant for seasonal temperature expected. Refer to TM 5-2420-231-10 for operator level lubrication
instructions.
3. Dashed leader lines (---) used in illustrations of lubrication points indicate that lubrication is required on both
sides of the machine.
4. Before you start your lube service:
ALWAYS
NEVER
Clean grease fittings before lubrication.
Use wrong type/grade grease.
Use the lubrication order as your guide.
Use too much lubricant.
5. Oil filters shall be serviced/cleaned/changed as applicable:
a. When they are known to be contaminated or clogged.
b. At prescribed hardtime intervals.
6. The tractor, wheeled, industrial backhoe loaders (BHL) are not enrolled in the Army Oil Analysis Program
(AOAP). HARDTIME INTERVALS APPLY.
7. For equipment under manufacturer's warranty, hardtime oil service intervals shall be followed. Intervals shall
be shortened if lubricants are known to be contaminated or if operation is under adverse conditions (i.e.,
longer-than-usual operating hours, extended idling periods, extreme dust).
8. For arctic operation, refer to FM 9-207, Operation and Maintenance of Ordnance Materiel in Cold Weather for
