3-13. MAINTENANCE UNDER UNUSUAL CONDITIONS-Continued.
Suspension. Clean and lubricate all parts as specified in Appendix F. Lubricate generously into each
lubrication fitting to force out any water.
Batteries. Check the batteries for level of electrolyte to be sure that no water entered through the vent
caps. This is important if the vehicle was submerged in salt water.
Electrical connections. Check all electrical connections for corrosion.
Fuel system. Drain fuel tanks of any accumulated water.
Air cleaners. If water is found in the air cleaner, clean and dry the filter element (see para. 3-10).
Condensation. The sudden cooling of the warm interior air upon submersion might cause condensation of
moisture within instruments. A period of exposure to warm air after fording should eliminate this condition.
Vision devices. If moisture has entered optical instruments, turn them in to unit maintenance for repair at
Perform authorized lubrication services (refer to TM 9-1005-213-10 for caliber .50 machine gun).
Cleaning and lubrication. Drain or wipe dry all trapped moisture. Clean all exposed parts and coat
with preservative lubricating oil. Refer to Appendix F.
Deep-water fording. Refer to TM 9-238 for deep-water fording information.
Maintenance After Operation on Unusual Terrain.
Mud. Clean and lubricate all parts as soon as possible after operation in mud. Refer to Appendix F.
Sand or dust. Clean engine and engine compartment. Touch up (Appx. D, item 17, 18, 19, or 20) all
painted surfaces damaged by wind-blown sand. Lubricate completely to force out any sand or dust. Air
cleaner dust covers must be cleaned daily. Oil coolers should be cleaned daily with compressed air. Notify
unit maintenance to check and clean fuel oil filters.
