Description

2005 M113A2 M577A2 M1064 M1068 M1059 M901A1 Unit Maintenance Manual TM 9-2350-261-20-3 Volume 3

The 2005 M113A2 M577A2 M1064 M1068 M1059 M901A1 Unit Maintenance Manual TM 9-2350-261-20-3 Volume 3 is a detailed unit-level maintenance reference for six tracked carrier configurations identified on the manual cover. Volume 3 concentrates on hull maintenance, access panels and floor plates, driver and commander hatch hardware, cargo and mortar hatch systems, ramp controls, hull welding guidance, smoke grenade launcher components, the ramp and suspension lockout hydraulic system, auxiliary generator fuel components, and personnel heater equipment. The procedures are organized as numbered work packages, allowing a mechanic to move directly to the component or task being serviced.

Built Around Unit Maintenance Work Packages

This volume is arranged for hands-on maintenance rather than general operating instruction. Individual work packages identify the maintenance level and commonly specify required tools, materials or parts, personnel, and the equipment condition that should exist before work begins. Depending on the job, the procedure then walks through removal, disassembly, cleaning, inspection, repair or replacement, assembly, installation, adjustment, service, and follow-through checks. Safety warnings and cautions are positioned with the applicable task, while many procedures provide exact tightening torques, clearances, or adjustment dimensions where the work requires them.

The manual also distinguishes between carrier configurations inside the procedures. Examples include model-specific power plant rear access panels, floor plates, hatch systems, seating, stowage equipment, generator or auxiliary power equipment, armor and launcher supports, mortar hatch hardware, and heater plumbing. That model-specific organization is valuable when several M113-family configurations are maintained in the same shop because it helps the technician follow the steps written for the actual carrier rather than treating all variants as identical.

Taken as a whole, TM 9-2350-261-20-3 Volume 3 gives a unit mechanic a structured set of component-level maintenance instructions for body, access, hatch, ramp, hydraulic, auxiliary power, and heating systems across the listed carrier variants. The combination of illustrated removal and installation steps, exploded assemblies, configuration notes, warnings, torque instructions, and adjustment criteria makes the volume especially useful when work extends beyond routine checks and requires parts to be removed, inspected, repaired, adjusted, or reinstalled correctly.

Illustrated Procedures and Configuration-Specific Detail

Many work packages pair the written steps with line drawings that show component locations, attachment hardware, assemblies, and installation relationships. For example, the towing pintle procedure includes removal, disassembly, inspection, assembly, and installation views; hatch and cupola procedures illustrate locks, springs, seals, latches, supports, and mounting hardware; and the hydraulic chapter includes a fluid-flow diagram identifying the ramp control valve, hydraulic tank, strainer, pressure relief valve, ramp pump, ramp cylinder, and model-specific breather arrangement. These illustrations help connect the numbered procedure steps to the physical parts being handled.

Adjustment data is included where the task depends on correct fit or engagement. Examples in this volume include hatch latch clearances, bumper compression, launcher bracket clearances, ramp and hatch engagement dimensions, and numerous specified tightening torques. The manual also calls out conditions that differ by model, early or late configuration, or installed equipment, so the reader can follow the branch that matches the carrier being maintained.

Put the Correct Procedure at the Work Area

The 2005 M113A2 M577A2 M1064 M1068 M1059 M901A1 Unit Maintenance Manual TM 9-2350-261-20-3 Volume 3 supports real unit-maintenance jobs such as removing and installing hull hardware, repairing hatch and cupola assemblies, adjusting ramp mechanisms, servicing hydraulic components, replacing heater fuel and air-system parts, and completing model-specific body or stowage work. Using the documented sequence, safety information, inspection points, torque values, and adjustment measurements helps reduce guesswork when parts must go back together in the correct position and condition.
