Description

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

This M911 parts and special tools manual is the Department of the Army technical reference for the Truck, Tractor, Commercial Heavy Equipment Transporter, C-HET, 85,000 GVWR, 8 x 6, Army Model M911, NSN 2320-01-025-3733. TM 9-2320-270-34P is arranged for Direct Support and General Support maintenance and provides the illustrated repair-parts information, special-tool listings, stock-number references, part-number references, and maintenance coding needed to identify components throughout the vehicle.

The M911 C-HET Heavy Equipment Transporter Repair Parts & Special Tools Manual TM 9-2320-270-34P (1989) is especially useful when the job is not simply to identify a major assembly, but to work down to the individual hardware, seals, bearings, brackets, hoses, fittings, gears, valves, electrical components, repair kits, and other service parts that make up that assembly. The illustrated figures are paired with detailed parts listings showing item numbers, SMR codes, FSCM numbers, part numbers, descriptions, usable-on information where applicable, and quantity information.

Illustrated Parts Identification and Support Information

This is an RPSTL rather than a conventional step-by-step repair procedure manual. Its purpose is to list and authorize the spares, repair parts, special tools, special test, measurement and diagnostic equipment, and other support equipment used for Direct Support and General Support maintenance. It also explains the Source, Maintenance and Recoverability codes used to determine how an item is obtained, the maintenance level authorized to use or repair it, and the disposition of an unserviceable item.

The repair-parts section is organized by functional group, with associated illustrations and item numbers. This makes it possible to start with an assembly or subassembly, locate the part visually, and then match that callout to the corresponding stock and part information. The manual also explains how to locate a component when either the NSN or part number is already known.

Engine-related listings distinguish parts used on 8V92T and 8V92TA engines, including early and late 8V92T applications where the publication identifies them. Examples include engine covers, camshafts, fuel-injection components, intake arrangements, turbocharger parts, and the aftercooler installation associated with the 8V92TA engine. These application notes are valuable when similar-looking assemblies use different components.

Across these groups, the manual moves from complete assemblies to detailed exploded views and component-level listings. Engine figures cover items such as cylinder liners, cylinder heads, crankshafts, flywheel components, pistons, camshafts, rocker gear, lubrication components, fuel injectors, turbochargers and governors. Chassis sections extend the same illustrated-parts approach through transmission, transfer case, axles, brakes, steering, suspension, frame, cab, accessories and the M911 winch system.

Parts Numbers, NSNs and Cross-References

A major strength of this M911 repair parts manual is the cross-reference structure. The National Stock Number Index is arranged by NIIN and points back to the applicable figure and item number. The Part Number Index provides an alphanumeric route from a known manufacturer or supply part number to its stock number and illustrated location. A separate Figure and Item Number Index links figure callouts with stock numbers, FSCM information and part numbers.

This arrangement supports several practical workflows. If the part number is unknown, the technician can identify the relevant functional group, locate the correct illustration, identify the item visually and then use the figure/item references to find its stock information. When an NSN or part number is already available, the indexes lead directly back to the relevant illustration so the component can be verified before requisitioning.

Special Tools and Maintenance Support

The special-tools section extends well beyond ordinary hand-tool identification. It contains illustrated listings for organizational, Direct Support and General Support tooling, including specialized fixtures, pullers, installers, removers, gauges, injector tools, blower-service tooling, fuel-pump tooling, torque-multiplier equipment, clutch-spring tools and other equipment identified for support work on M911 systems.

The publication also includes Basis of Issue information where applicable to special tools and explains the coding used for maintenance authorization. This helps distinguish a component that can be replaced at a particular maintenance level from one that is repaired, fabricated, assembled, recovered or disposed of under different support criteria.

Important Manual Scope

The M911 C-HET Heavy Equipment Transporter Repair Parts & Special Tools Manual TM 9-2320-270-34P (1989) is primarily a parts-identification, supply-reference and special-tools publication. It does not replace the separate M911 maintenance manuals for detailed repair, fabrication or assembly procedures. The publication itself refers users to TM 9-2320-270-10, TM 9-2320-270-20 and TM 9-2320-270-34 for applicable detailed instructions. This makes TM 9-2320-270-34P particularly useful alongside the procedural maintenance manuals when the technician needs the exact illustrated component, part number, stock reference, quantity, maintenance code or special tool associated with the work.
