TM 9-2320-387-10 Change 1 2-113 NOTE • Hydrostatic lock is caused by the entry of substantial amounts of water into the engine through the air intake system and subsequent contamination of the fuel system. Hydrostatic lock most frequently occurs during or just after fording. Water is forced into the air intake system, drawn into the engine, and locks up the engine. • Notify unit maintenance if you suspect hydrostatic lock and they will test the engine. d. After Operation. .WARNING. Do not rely on service brakes after fording until the brakes dry out. Keep applying brakes until uneven braking ceases. Failure to do this may cause damage to vehicle or injury or death to personnel. NOTE If accumulated water drains slowly through floor drain holes, refer to unit maintenance for drilling and improving drain holes. (1) If fording operation was through salt water, wash and wipe off salt deposits as soon as possible. NOTE To prevent parking brake linkage from binding, lithium grease should be used after operating in water. (2) Clean mud, grit, and debris from brake linkage. Apply lithium grease (appendix D, item 14), and move linkage back and forth to work into joints. (3) After shallow water fording operation, vehicle must be lubricated and serviced by unit maintenance as soon as possible. BRAKE LINKAGE
