Description

1989 M911 C-HET Heavy Equipment Transporter Repair Parts & Special Tools Manual TM 9-2320-270-34P

This 1989 M911 C-HET Heavy Equipment Transporter Repair Parts & Special Tools Manual TM 9-2320-270-34P is the Direct Support and General Support Maintenance Repair Parts and Special Tools List for the Truck, Tractor, Commercial Heavy Equipment Transporter, C-HET, 85,000 GVWR, 8 X 6, Army Model M911. The publication is organized around illustrated assemblies and detailed parts listings, giving maintenance personnel a structured way to identify components, relate each callout to its part listing, and locate National Stock Number and part-number references. It also includes the special tools and support equipment identified for Direct Support and General Support maintenance.

The manual is especially useful when a repair task has reached the parts-identification stage. Illustrations show assemblies and subassemblies with numbered callouts, while the adjoining lists provide item numbers, SMR codes, FSCM entries, part numbers, descriptions and quantities. The introduction explains how to use those fields, how source, maintenance and recoverability codes are interpreted, and how to work from either an unknown part or a known NSN or part number to the appropriate figure and item entry.

What the Parts Listings Provide

The M911 repair parts manual is arranged as a functional illustrated parts catalog rather than a step-by-step repair procedure book. Section II lists spares and repair parts by functional group and figure/item sequence. Individual entries can include the source, maintenance and recoverability code, the Federal Supply Code for Manufacturer, the part number, item description and quantity used in the illustrated breakout. Repair kits and bulk materials are also included in dedicated groups. This layout makes the manual practical for identifying what belongs in an assembly, checking the relationship between nearby components, and tracing a listed item back through the indexes.

The publication also explains how to locate a repair part when the NSN or part number is not known: first identify the assembly or subassembly group, locate the applicable figure, identify the callout, then use the Figure and Item Number Index to find the stock-number information. When an NSN or part number is already known, the National Stock Number Index or Part Number Index cross-references the item to the relevant figure and item number.

Across these groups, TM 9-2320-270-34P reaches from the M911 powerplant and fuel system through the transmission, transfer case, axles, brakes, steering, chassis, cab and winch equipment. The parts figures include complete assemblies as well as exploded views for components such as the turbocharger, blower, transmission and transfer case. Engine-related listings distinguish applications for the 8V92T and 8V92TA where the publication calls for different components, including turbocharger, aftercooler, injector and related engine parts.

Special Tools and Maintenance Support Information

The special-tools section extends the catalog beyond replacement parts. It identifies organizational, Direct Support and General Support tools and test equipment used with the M911 systems. Examples shown in the manual include wheel-bearing wrenches, installers and removers, electrical terminal tools, injector test equipment, measuring gages, torque-multiplier equipment and transmission service tools. This is valuable when the required maintenance task depends on a specific tool or fixture and the technician needs its listed identification rather than a generic substitute.

The SMR coding guidance is another important part of the M911 C-HET parts reference. The manual explains how the five-position code communicates the source of an item, the maintenance level authorized to remove, replace or use it, the level capable of complete repair, and the recoverability or disposition requirement. That information gives the illustrated parts listings their maintenance-support context and helps the reader interpret why different components are handled differently in the supply and repair system.

The 1989 M911 C-HET Heavy Equipment Transporter Repair Parts & Special Tools Manual TM 9-2320-270-34P is built for detailed component identification during Direct Support and General Support maintenance. Use it to follow illustrated assemblies, identify repair parts and kits, check part and stock-number references, distinguish listed 8V92T and 8V92TA applications, trace transmission, axle, brake, steering and winch components, and identify the special tools called out for supported work. Because this is an RPSTL, it is primarily a parts-identification, supply-reference and special-tools publication rather than a step-by-step repair-procedure manual.

Accurate figure callouts, part numbers, SMR information and cross-reference indexes matter when a repair depends on ordering or identifying the correct component.
