UH-1B UH-1C UH-1H UH-1M EH-1H UH-1V Helicopter Repair Parts Manual TM 55-1520-210-23P-2 Volume 2

Description

UH-1B UH-1C UH-1H UH-1M EH-1H UH-1V Helicopter Repair Parts Manual — TM 55-1520-210-23P-2, Volume 2

This is Volume 2 of the Aviation Unit and Intermediate Maintenance Repair Parts and Special Tools List covering the Bell UH-1 series utility tactical transport helicopters. Issued under Technical Manual TM 55-1520-210-23P-2, this volume walks through Section II Functional Groups 07 through 14 — the systems that carry hydraulic fluid, drive the instruments, distribute electrical power, deliver fuel, move the flight controls, and support the cargo hoist. It is the parts look-up companion a maintenance shop reaches for when a servo cylinder, caution panel, hydraulic tank, generator, fuel line, torque tube or hoist component has to be identified and ordered by its official stock number.

Functional Groups Covered in This Volume

Volume 2 of TM 55-1520-210-23P-2 picks up where Volume 1 stops, covering Functional Groups 07 through 14 in the standard Army functional-group breakdown. Each group is presented as an illustrated parts list with figure and item call-outs matched to a tabular parts list.

• Functional Group 07 — Hydraulic and Pneumatic System: servo cylinders, hydraulic installation forward, center and aft sections, hydraulic fluid tank, lines, valves, fittings and hardware.
• Functional Group 08 — Instrument Systems: instrument panel and pedestal installation, glare shield assembly, instrument panel assemblies (left-hand and center sections), flight instrument mounting and bezels.
• Functional Group 09 — Electrical Systems: electrical installation forward section, master caution panel assembly, word caution control panel, electrical overhead console panels, engine control panel, pylon electrical installation, direct current generator, starter installation, aft section electrical installation, rescue hoist and door gunners foot mike switch, armament electrical installation.
• Functional Group 10 — Fuel System: upper tank section fuel system installation, auxiliary fuel tank lines and installations.
• Functional Group 12 — Flight Control Systems: collective pitch control jackshaft installation, tail rotor control installation forward and aft sections, tail rotor control cable installation, synchronized elevator forward and aft control installations, engine bleed air detection system and valve installation, distribution system aft section installation.
• Functional Group 14 — Hoist and Winches: cargo suspension installation, cargo hook, release assembly, case and cover assemblies.

How the Parts Data Is Organized

Every functional group in this UH-1 parts manual opens with an exploded or isometric figure that carries index numbers keyed to the parts-list table that follows. Each table row supplies the figure number, item number, SMR code, National Stock Number, FSCM, part number, description, usable-on code, unit of measure and quantity per assembly. Usable-on codes call out exactly which airframe the line item applies to — UH-1B, UH-1C, UH-1H, UH-1M, EH-1H or UH-1V — so a part that only fits one variant is immediately distinguishable from a common one. That structure is what makes this repair parts and special tools list practical for a working shop: you identify the assembly on the illustration, read the item number, then look the number up in the table to get the NSN and part number you need to place an order or cross-reference a substitute.

NSN Coverage by Airframe

The manual is issued against the following National Stock Numbers, which identify the airframes the parts data is authorized for:

• UH-1B — NSN 1520-00-713-9912
• UH-1C — NSN 1520-00-997-8862
• UH-1H — NSN 1520-00-087-7637
• UH-1M — NSN 1520-00-809-2631
• EH-1H — NSN 1520-00-368-8442
• UH-1V — NSN 1520-01-043-4949

What This UH-1 Parts Manual Lets You Do

With this Volume 2 repair parts and special tools list on the bench, a maintainer can identify and order the correct hydraulic servo cylinder, hydraulic installation line, hydraulic fluid tank component, instrument panel fastener, caution panel lamp, engine control switch, fuel tank line, tail rotor control cable, collective pitch jackshaft, cargo hook or suspension component for any of the six covered Huey variants. Instead of guessing at a part by shape or an aftermarket crossover, you are working directly from the official stock number and part number data the Army publishes for these aircraft. The illustrated breakdowns also make it straightforward to confirm how a subassembly is put together before disassembly, and to check whether a particular item is shown under multiple usable-on codes when a common part is shared across the UH-1B, UH-1C, UH-1H, UH-1M, EH-1H and UH-1V.

Why Correct Parts Data Matters on the UH-1

The UH-1 airframe was built in enough variants that a part which physically fits one model can be wrong for another because of a difference in hydraulic routing, electrical wiring, or control linkage. This manual handles that problem with the usable-on code column: each line item shows precisely which models the item is approved for. Using the correct NSN and part number the first time keeps a maintenance action moving, keeps the aircraft in a legal configuration, and avoids the delay that comes with a returned part or a re-ordered substitute. For anyone doing scheduled maintenance, unscheduled repair or a full parts inventory on a UH-1B, UH-1C, UH-1H, UH-1M, EH-1H or UH-1V, this volume is the reference that answers the parts questions the operator manuals do not.
