Between those six chapters, the manual documents the whole M1117 ASV operating envelope: the Cummins 6-cylinder turbocharged diesel and Allison 6-speed automatic drivetrain, the four-wheel drive transfer case with neutral lock-out, the independent coil-spring suspension, the Meritor hydraulic brake system with accumulator assist, the central tire inflation system, the 15,000 lb hydraulic winch, the M13A1 NBC system, the automatic fire extinguisher system, and the full turret weapon station with its 40-mm MK-19, M48 .50-cal. M2HB, and M257 smoke grenade launchers. It also covers the driver’s and commander’s controls and instruments for both the 200 Amp and 400 Amp driver’s control unit variants, the turret traverse and elevation controls, gunner’s sight, periscopes, boresighting, and both electrical and manual firing procedures.

What This Manual Lets You Do

The M1117 ASV is a four-wheel drive armored vehicle with a closely integrated turret weapon station, and this manual is structured around the daily realities of running it — not a general reference. The PMCS tables tell you exactly what to inspect before, during, and after every mission, with pass/fail criteria for each item so you know what makes a vehicle not mission capable. The operator troubleshooting work packages walk you through real symptoms like engine cranks but does not start, CTIS lights flashing, low oil pressure warning, transmission Do Not Shift light, turret does not power traverse, and M48 .50-cal. does not fire electrically, each with step-by-step decision logic to isolate the fault.

Weapon handling is covered end to end. You get ammunition loading for both the MK-19 40-mm and the M48 .50-cal., replenishing the last link of 40-mm inside the turret, charging procedures, minor boresighting on both day and night sights, and weapons clearing. Stoppage immediate actions and weapons malfunction procedures give you the correct response to a misfire, hangfire, cookoff, or runaway gun before someone gets hurt.

Unusual conditions are handled separately — fording up to 60 inches of water with the turret hatch open as an escape hatch, crossing vertical obstacles up to 22 inches, tire chain installation with CTIS deflation steps, arctic weather starting with the auxiliary heater and battery heaters, high altitude operation, NBC system operation, and driver’s night vision goggles. Like-vehicle towing, winching with and without a snatch block, slave receptacle starting, and hand-held and automatic fire extinguisher operation are all covered in dedicated work packages.

Beyond procedures, the manual also includes the full vehicle equipment data — performance figures, dimensions, weight, ground clearance, engine and transmission data, tire pressures with and without Frag Kit 2, fluid capacities, electrical system ratings, and turret equipment data. Ammunition stowage locations, COEI/BII lists, the AAL, and the expendable and durable items list round out the reference material so you know exactly what should be on the vehicle and what to reorder.

Why This Reference Matters

On an armored vehicle, an incorrect procedure is not just inconvenient — it can damage the drivetrain, disable the turret, or hurt the crew. This manual is the difference between guessing at a warning light and knowing which circuit breaker, solenoid, connector, or switch to check, in order. The torque and pressure values, CTIS settings, tire pressures, oil capacities, and service intervals are printed exactly as the U.S. Army TACOM Life Cycle Management Command issued them, so you are working from the same numbers the operator and maintainer were trained on.

For collectors, reenactors, vehicle restorers, and anyone supporting an M1117 ASV, having the actual operator’s manual TM 9-2320-381-10 at hand makes every daily check, fuel-up, drive, and range session safer and more efficient. For crews and instructors, the PMCS tables and troubleshooting work packages double as training material and as a check against skipping steps under pressure.
