Description

Bell UH-1B UH-1C UH-1H UH-1M EH-1H UH-1V Repair Parts & Special Tools Manual TM 55-1520-210-23P-1

This 588-page technical manual is the Aviation Unit and Intermediate Maintenance Repair Parts and Special Tools List for the UH-1B, UH-1C, UH-1H, UH-1M, EH-1H and UH-1V utility tactical transport helicopter family. The document is TM 55-1520-210-23P-1, dated 27 February 1981, and the copy incorporates an extensive sequence of later change material. Its purpose is parts identification and maintenance-support reference: illustrated assembly breakdowns are paired with detailed listings containing stock numbers, manufacturer codes, part numbers, descriptions, applicability codes, units of measure and quantities.

The Bell UH-1B UH-1C UH-1H UH-1M EH-1H UH-1V Repair Parts & Special Tools Manual TM 55-1520-210-23P-1 is especially useful when a component must be traced from a major helicopter assembly down to an individual listed item. Figures identify components by callout number, while the accompanying tables provide the data required to distinguish parts and determine their relationship to the next higher assembly.

Important Volume Coverage

TM 55-1520-210-23P is arranged as a three-volume publication. This PDF is TM 55-1520-210-23P-1, the first volume. The manual identifies this volume as containing the Table of Contents, Section I and Section II material for Functional Groups 02 through 06. Later functional groups continue in TM 55-1520-210-23P-2 and TM 55-1520-210-23P-3, with additional sections also assigned to the third volume. Buyers looking specifically for this -23P-1 volume therefore receive the detailed early-system repair-parts coverage contained here, rather than all three volumes combined.

What the Parts Listings Provide

The repair-parts section is organized by functional group and normally follows assembly and disassembly relationships. Illustrations precede the corresponding parts listings so a technician can first locate a component visually and then match its figure and item number to the tabular data. The listings contain National Stock Numbers where assigned, manufacturer identification data, part numbers, item descriptions, usable-on codes, units of measure and quantities incorporated in the unit.

The introduction also explains the Source, Maintenance and Recoverability code system used throughout the parts tables. These SMR codes identify such information as how a support item is obtained, the maintenance level authorized to remove or use it, the level capable of complete repair and the prescribed disposition of an unserviceable item. This makes the manual considerably more useful than a simple illustrated parts catalog: the tables preserve the maintenance-support coding attached to the listed components.

Model applicability is handled through usable-on codes and, where necessary, effectivity information within individual listings. The manual also explains replacement relationships, next-higher-assembly references, oversize and undersize parts, manufactured or fabricated items, quantity information and the conventions used when a component breakdown continues in another figure.

Chapters Covered

  • Section I – Introduction
    • Scope of the repair parts and maintenance-support listing
    • Organization of repair parts, special tools and index information across the publication set
    • Explanation of illustration and item-number columns
    • Source, Maintenance and Recoverability codes
    • National Stock Number and part-number information
    • Federal Supply Code for Manufacturer information
    • Description, unit-of-measure and quantity columns
    • Usable-on codes and model applicability
    • Special information for replacement and assembly relationships
    • Methods for locating repair parts
    • Abbreviations and mnemonic codes
  • Section II – Repair Parts List, Functional Groups 02 through 06
    • Airframe assemblies and structural sections
    • Forward and aft helicopter section assemblies
    • Tail boom assemblies and tail boom installation
    • Tail rotor shaft access-door components
    • Forward fuselage assemblies
    • Nose door, nose installation and cabin nose assemblies
    • Cutter installation and component breakdowns
    • Cabin windshield installation
    • Crew-door assemblies, latches and related hardware
    • Cabin panels and roof installations
    • Seat, armor-seat and passenger-seat installations
    • Skid landing-gear assembly
    • Power plant installation and engine assembly-related parts
    • Engine external oil-filter unit assemblies and associated equipment shown in the listings
    • Transmission and mast assembly
    • Engine-to-transmission drive-shaft installation
    • Lower pylon installation
    • Tail-rotor drive-shaft installation
    • Tail-rotor hub and blade assembly
    • Synchronized elevator installation

Across these groups, the document moves from broad helicopter assemblies into increasingly detailed component breakdowns. Exploded drawings show the spatial relationship between assemblies, brackets, panels, skins, structural members, fasteners and other components, while the facing or following tables identify the associated figure items. Many entries also carry applicability information so differences between UH-1 variants can be distinguished instead of treating every listed component as universally interchangeable.

Illustrated Component Identification

A major strength of this UH-1 repair parts manual is its large number of line drawings and exploded views. Early overview illustrations show the helicopter broken into principal assemblies, including the forward and aft sections, skid landing gear, power plant, transmission and mast, engine-to-transmission drive shaft, pylon, tail-rotor drive, tail-rotor hub and synchronized elevator. More detailed figures then expand individual structures and installations.

Examples include multi-sheet tail-boom drawings showing skins, stringers, bulkheads, supports, fin structure and associated attachment points; forward-fuselage illustrations with numerous numbered callouts; nose and cabin installation drawings; cutter-system breakdowns; and other assembly-level diagrams. These visual references are directly linked to the item numbers in the parts tables, allowing the reader to work from the physical location of a component toward its listed identification data.

Parts Identification and Applicability Data

TM 55-1520-210-23P-1 is designed around exact component identification. A typical listing may show the illustration figure and item number, SMR code, National Stock Number, manufacturer code, part number, component description, usable-on code, unit of measure and quantity incorporated. Where configuration differences exist, entries may include specific usable-effectivity information or references to another figure for the next higher assembly or further breakdown.

The introduction provides instructions for finding a part even when its National Stock Number or part number is not already known. The reader can identify the relevant assembly, locate the component in its illustration, note the figure and item number and then use the corresponding repair-parts listing. This arrangement is valuable for maintenance, restoration, inventory research and parts cross-reference work where the physical component is known but its exact listed identity is not.

Because the publication contains historical change material and model-specific applicability, it also preserves configuration information that can be important when comparing assemblies from different UH-1 variants. The listings should be read together with their usable-on and effectivity information rather than assuming that visually similar parts apply to every model.

Identify UH-1 Components with the Correct Illustrated Reference

The Bell UH-1B UH-1C UH-1H UH-1M EH-1H UH-1V Repair Parts & Special Tools Manual TM 55-1520-210-23P-1 gives technicians, maintainers, restorers and parts researchers a structured reference for identifying airframe, landing-gear, power-plant and related Functional Group 02-06 components contained in this first volume. Its exploded views and figure/item system make it possible to trace assemblies to individual listed parts, compare model applicability, locate stock and part numbers, and understand the maintenance-support coding attached to those items.

Using the correct figure, part number, NSN, usable-on code and assembly relationship helps avoid ordering or identifying a component from the wrong configuration. After purchase, the manual is supplied as an instant PDF download with no physical shipping required. It can be viewed on a computer, tablet or phone and pages can be printed whenever a paper reference is useful at the workbench.
