APPENDIX J: LUBRlCATION INSTRUCTIONS
J-1 GENERAL STATEMENTS-Continued
c. MAINTENANCE LEVEL
The maintenance level for all lubrication services in this appendix is Unit.
d. EXCEPTIONAL OPERATIONAL REQUIREMENTS
Lubricate more often to compensate for abnormal and extreme conditions. High or low temperatures, prolonged
periods of high rate operation, continued operation in sand, dust, or exposure to moisture may quickly destroy
the protective qualities of the lubricant. Before performing lubrication checks and services, observe the following:
1
Never use incorrect lubricant or use too much lubricant.
2 A l w a y s :
a.
Clean grease fittings before lubrication
b.
Use this appendix as a guide
c.
Lubricate after fording
d.
Ensure vehicle is level prior to checking fluid levels.
3
Lubrication after fording operations.
As soon as possible after any fording operation in water of 12 inches or more, lubricate all chassis points to
cleanse of water of grit. Also lubricate any other points requiring maintenance after fording. If vehicle has
been in deep water for a considerable length of time, or was submerged beyond its fording capabilities, the
following precautions must be taken as soon as practicable to avoid damage to engine and other vehicle
components:
a.
Perform a complete lubrication service.
b.
Check APU, main engine and transmission for presence of water or sludge in oil. If found, drain and
flush transmission with PE-1 Lubricating Oil, Internal Combustion engine, and drain and flush engines
with OE-30 Lubricating Oil, Internal Combustion engine. If PE-1 is not available, flush transmission with
OE-10 Lubricating Oil, Internal Combustion engine. Before refilling with clean oil, remove, clean, and
install transmission oil filters (see paragraph 7-2). Replace engine oil filter elements (see paragraph 3-6).
c. Check lubricant in hydraulic reservoir and winch gear cases for evidence of water or sludge
contamination. If there is evidence of contamination, drain and refill with correct lubricant.
4
For operation of equipment in protracted cold temperatures below -10°F (-23°C).
Remove lubricants prescribed in table for temperatures above -10°F (-23°C). Clean parts with dry-cleaning
solvent, type II (Appendix D, item 9) or equivalent. Relubricate with lubricants specified in table J-l,
Lubricant Table for M88A1 Medium Recovery Vehicle, for temperatures of 0 F to -65°F (-18°C to -50°C).
