LTI Maintenance Flashcards
Engine. Run engine for 10 minutes at high idle (1000 rpm) with air conditioning at maximum cool and all electrical accessories activated. Monitor dash gauges during test for any abnormal readings. After test inspect for any fluid leakage under and around engine.
Weekly
Aerial Hours. Note and record current aerial hours.
Bi-monthly
Air tank(s). Drain each and every air tank of water and oil contaminants. Inspect for any abnormal amounts of oil drained from air tanks.
Weekly
Steering Box and Steering linkage. (Engine shut down). Position front wheels straight ahead (wheels on ground). Have an assistant move the steering wheel back and forth with short (4 to 6) rapid movements. At the same time inspect steering linkage and connections for any looseness or excessive movement. You can place your finger on the two mating parts of each steering connection and “feel” for any disproportionate movement between the two. Any detectable movement should be noted and reported.
Bi-monthly
Onan generator. Run the engine with an electrical load until warm. Check operation and check for leaks.
Weekly
Differential. Check oil level. Oil level should be even with the plug opening.
Bi-monthly
Air Cleaner. CAB FULL TILT POSITION. Inspect hose(s), ducts, pipe, connections, etc. between air cleaner and engine intake for wear, breaks, and mounting. Air cleaner element is to be replaced every other year or on an “as needed” basis. This is determined by the amount of inlet restriction measured by the engine’s diagnostic system.
Bi-monthly
Engine water pump. CAB FULL TILT POSITION. Check water pump for evidence of coolant leakage. Look at condition of coolant hose and connections.
Weekly
Generator Hours. Note and record current Onan generator hours.
Bi-monthly
Fuel Supply. Maintain to capacity.
Daily
Engine. Look for any signs of fluid leakage.
Daily
Engine Hours. Note and record current engine hours.
Bi-monthly
Odometer reading. Note and record current mileage.
Bi-monthly
Tires. With the approved tire tread depth gauge, measure depth at the center fo the tire tread. A reading of 1/8” or less should be reported on the F-377 and called in for needing replacement
Bi-monthly
Engine mounts. CAB FULL TILT POSITION. Inspect engine mounts for looseness and/or damage to rubber mounts
Bi-monthly
Wiring. CAB FULL TILT POSITION. Perform visual ONLY of all wiring in engine compartment for routing, connections, wear and/or corrosion
Bi-monthly
Brakes. (Engine shut down). Inspect all mechanical components for looseness, wear, breakage and/or missing components. Inspect air lines for leakage, wear and/or breaks. Inspect brake linings and rotors for wear, cracks and breaks. Inspect brake push rod travel for a maximum 2” stroke on all six wheels. When applying and holding the brakes for brake push rod travel measurement, grasp and shake the brake line(s) to the brake chamber and listen for any air leakage.
Bi-monthly
Tires. Check pressure by gauge. Check for loose, broken and/or missing wheel lugs.
Weekly
Oil, Onan engine. Maintain to capacity.
Daily
Seat belts. Look for cuts/deterioration. Check operation of latch mechanism and integrity of mounts.
Daily
Tire/wheels. Perform visual check on wheels and tires. Inspect tire tread and sidewall condition for excessive wear, any cuts, and bruises or tread separation. Inspect wheels for loose, missing or broken wheel lugs; cracks, bends or any wheel misalignment.
Daily
Running Gear (Powertrain). Look for conditions/tightness of bolts, nuts, fittings, shafts, cables, etc.
