Description

M109A2 M109A3 M109A4 M109A5 Howitzer Hull TM 9-2350-311-24P-1 Repair Parts Manual

This is the official U.S. Army Repair Parts and Special Tools List (RPSTL) covering the hull of the M109A2, M109A3, M109A4, and M109A5 155mm self-propelled howitzers, published under manual number TM 9-2350-311-24P-1. If you maintain a M109-series howitzer chassis at unit, direct support, general support, or depot level, this M109A2 M109A3 M109A4 M109A5 Howitzer Hull TM 9-2350-311-24P-1 Repair Parts Manual is the parts-identification reference your shop needs on the bench.

This volume is scoped specifically to the hull — the automotive/chassis structure and its supporting systems — rather than the turret or main armament, so buyers looking for the turret/weapon-system parts list should confirm that separately. Each of the four variants carries its own National Item Identification Number and Equipment Identification Code as listed on the manual’s title page: M109A2 (NSN 2350-01-031-0586, EIC 3EZ), M109A3 (NSN 2350-01-031-8851, EIC 3E2), M109A4 (NSN 2350-01-277-5770, EIC 3E8), and M109A5 (NSN 2350-01-281-1719, EIC 3E7), and this manual applies its hull parts listings across all four.

Across these sections, the M109A2 M109A3 M109A4 M109A5 Howitzer Hull TM 9-2350-311-24P-1 Repair Parts Manual gives a technician a complete, illustration-referenced parts trail from the powerpack down to hull hardware: every listed part carries an item number tied to its figure, an SMR code that tells you sourcing, maintenance-level authorization, and disposition, plus the National Stock Number and part number needed to requisition it correctly. The cross-reference indexes in Section IV let you work backward from an NSN or part number you already have in hand to find exactly where it fits in the hull.

What’s Inside the Repair Parts List

The Repair Parts List makes up the bulk of the manual, and it is organized so the powerpack and its supporting systems come first: Group 01 covers both engine variants used across the fleet (7083-7396 and 7083-7391), their container assemblies, mounting base, vibration damper, breather hoses, and oil filter and transmission coolant hose runs. Group 03 continues into the fuel system — fuel pump and hanger assemblies, air cleaner ducting, fan and element assemblies, fuel lines and fittings, both upper and lower fuel tanks with their retaining hardware and heat shields, and the accelerator, throttle, and fuel shutoff linkage. Group 04 covers exhaust piping and insulation, and Group 05 covers the cooling system in depth: the radiator surge tank, engine coolant radiator and cap, aeration detector assembly, coolant shroud, thermostats, and the cooling fan drive assembly with its vaneaxial fan and gear case.

Group 06’s electrical section runs from the alternator and voltage regulator through the bilge pump relay, circuit breaker panel, driver’s instrument panel assemblies (with separate listings for the different engine configurations), the driver’s portable instrument panel and its cover and bracket assemblies, low coolant indicator wiring, and the accessory control box. From there the parts list moves through Group 07 Transmission, Group 08 Transfer and Final Drive Assemblies, Group 12 Brakes, Group 13 Wheels and Tracks, Group 14 Steering, Group 15 Frame/Towing Attachments/Drawbars, and Group 16 Springs and Shock Absorbers — the full automotive chassis path that keeps the vehicle moving.

Group 18 is where the hull itself takes center stage: driver’s portable instrument panel mounting bracket, hull front intake and exhaust grilles, hull front plates and access doors, personnel air ventilator components, the travel lock assembly, bulkhead insulation and access covers, torsion bar anchor access plates, hull rear doors with their seals and hold-open latches (separate listings account for A2/A4/A5 versus certain A3 vehicle configurations), fenders, the driver’s hatch cover and periscope covers, subfloor drains, driver’s and loader’s seat assemblies, powder can stowage straps, ammunition racks, the fire extinguisher bracket, interior stowage hardware, and the rations and NBC suit stowage boxes fitted to A4/A5 vehicles. Group 20 covers hoist, winch, capstan, and power take-off hardware, and Group 22 rounds out body, chassis, and hull accessory items. Groups 33, 47, 76, 91, 94, and 95 round out special purpose kits, non-electrical gages, fire fighting equipment, CBR equipment, repair kits, and general use standardized/bulk parts.

Understanding the SMR Codes

One of the most useful parts of this manual for anyone new to Army parts documentation is Section I’s breakdown of the SMR (Source, Maintenance, Recoverability) code system used throughout the Repair Parts List. The manual explains, position by position, how to read source codes (whether an item is stocked, kitted, fabricated, or assembled), maintenance codes (which maintenance level is authorized to remove, replace, use, or fully repair an item, from crew/operator level up through depot), and recoverability codes (whether an unserviceable item should be repaired, salvaged, or condemned). Having this key alongside the actual M109A2 M109A3 M109A4 M109A5 Howitzer Hull TM 9-2350-311-24P-1 Repair Parts Manual listings means you’re not just looking at a part number in isolation — you know immediately whether you’re authorized to order it, repair it, or need to escalate to a higher maintenance echelon, and whether cannibalization or controlled exchange is an option for that item.

Section III’s Special Tools List then documents the special tools, special test/measurement/diagnostic equipment (TMDE), and other special support equipment authorized for hull maintenance, including the pressure gage tester, with the same Basis of Issue detail found in the parts list. Section IV closes the manual with National Item Identification Number and part number cross-reference indexes, listing every NSN and part number in the manual against its Commercial and Government Entity Code (CAGEC) and figure/item number, so you can move in either direction between a part in hand and its place in the hull.

This manual is a parts and special-tools reference, not a step-by-step repair procedure manual, so it’s built for the moment you already know what assembly needs work and need to identify, cross-reference, and requisition the exact hull component — down to hatch seals, stowage hardware, and hull access covers — correctly the first time.
