Hitachi EX135UR Excavator Parts Catalog (P/N P1ED-1-3)

The Hitachi EX135UR Parts Catalog (P/N P1ED-1-3) covers excavators from serial number 001001~, with STD and EU parts identification and configurations with or without a blade. It provides illustrated parts information rather than step-by-step repair instructions.

Catalog Bookmarks and PDF Access

Search, navigation and drawing detail: Text search is not available for the catalog pages. Embedded bookmarks cover the major assemblies and parts index, although some bookmark labels differ from the printed page headings. Dense piping callouts benefit from zooming.

One printable PDF contains 570 pages, including the front and back covers, one memorandum page and 13 blank pages. The catalog contains English and Japanese text.

Hydraulic Assemblies, Undercarriage and Boom Parts

The following selected contents outline the catalog’s main areas. Other illustrated entries include clamshell bucket components and the mono-boom one-point ripper.

• Upperstructure and cooling: Illustrated parts lists for the engine support, radiator, reserve tank, fuel tank and associated mounting components.

• Hydraulic components: Pump devices, control valves and supports, suction and delivery piping, return lines and pilot valves, with configuration-specific piping drawings.

• Undercarriage and drives: Track frame, travel device, center joint and swing bearing diagrams, plus separate rubber-crawler and steel-crawler component listings.

• Boom attachments: Offset-boom and mono-boom parts, standard and long arms, cylinders, bucket linkages, pins, bushings and lubrication piping.

• Electrical equipment: Cab Harness and Light Harness drawings, controller and monitor components, relays and switches, with separate STD and EU electrical parts entries.

• Breaker and crusher connections: Mono-boom control pedal, pilot piping and main piping illustrations, plus boom, arm and OKD attachment piping parts.

This catalog is suited to mechanics and parts staff who can match illustrated assemblies, machine serial numbers and configuration notes when identifying replacement parts.

Parts Ordering and Serial Applicability

The catalog pairs numbered assembly drawings with OEM part numbers, quantities, service codes and replacement-part references to support shop-floor parts sourcing. The numerical parts index provides another route to a component when its part number is already known.

Interchangeability: The ICA column distinguishes one-way substitutions, assembly replacements and mutually interchangeable parts. A similar-looking component is therefore not enough to establish that a replacement can be used in both directions.

Serial changes: Pilot Piping (6) has separate layouts for 001001–001875 and 001876 onward. Offset Boom, Front Piping (1) and Front Piping Cover entries separate 001001–002053 from 002054 onward, helping identify the applicable drawing before selecting parts.

EU-specific reserve-tank and Electric Parts (2) pages start at 002392. Check the applicability shown for the relevant group and individual part instead of treating every illustrated configuration as interchangeable.

Assembly Detail and Repair Limits

The Swing Device and Travel Device drawings break out gears, thrust plates, bearings and seals. These views show how listed components relate to their assemblies; they do not establish a disassembly sequence or replace workshop repair procedures.

Hydraulic scope: Pump devices and many hydraulic cylinders are listed as assemblies with limited component breakdowns. Service code H identifies precision parts for which the catalog directs the reader to specialist repair.

Engine parts: The engine listing identifies the complete unit and selected items such as filters, switches, the belt and alternator. Internal parts for the Isuzu 4BG1 diesel engine require the separate engine parts catalog referenced in the foreword; that publication is not included.

The cab and lighting harness drawings identify assemblies and mounting parts. They are parts illustrations, not electrical circuit diagrams or diagnostic test charts.

Check machine identification and the applicable service instructions before ordering parts or working on pressurized hydraulic assemblies.

Selected Arm Lengths for Parts Matching

The offset-boom sections distinguish a standard arm measuring 2.21 m from a long arm measuring 2.51 m. Separate front-piping entries follow these arm configurations.

For the mono boom, the catalog identifies a 2.26 m standard arm and a 2.81 m long arm. These dimensions identify the attachment configuration for selecting the corresponding parts pages.
