IHI 35N Excavator Parts Catalog (P/N Pub. No. 2)

Ordering parts by appearance alone is risky on an IHI 35N because the catalog distinguishes revised components, optional equipment, and serial-specific assemblies. This 297-page IHI factory parts catalog, Pub. No. 2, covers the IHI 35N mini excavator from serial number WM000001 onward. Its keyed illustrations and parts tables were prepared for parts sales and servicing, with fields for quantity, serial applicability, remarks, change status, and interchangeability. The catalog is suited to parts personnel, repair shops, and experienced owners who can identify installed options and interpret exploded views; it is not beginner repair instruction.

• Identifies lower-machine components through exploded views of the rubber and steel crawler shoe arrangements, crawler shoe adjustment device, front idler, lower and upper rollers, and lower traction piping.
• Maps the turntable and swing bearing, swing drive device, traction and swing motors, rotary joint, hydraulic oil tank, oil pump, control valve, remote control valve, manifold, and hydraulic cylinders.
• Separates hydraulic piping and operating-control variants, including return and suction piping, swing and traction lines, control piping, short-lever equipment, suspension-seat arrangements, and the A-F change configuration.
• Documents the power-unit installation, radiator and oil cooler components, air cleaner and muffler, oil-pump drive, fuel tank and piping, electrical-system layout, and instrument-panel assembly.
• Covers the hoe and blade attachments, standard and long-arm equipment, boom-swing parts, attachment piping, and the available standard, reinforced, and hook-equipped bucket configurations.
• Provides old/new interchangeability markings, machine applicability ranges, assembly quantities, dimensional remarks, and a 19-page sequential parts-number index that links each listed number to its illustrated sheet and key position.

Serial Breaks and Configuration Coverage

Several assemblies are divided at the WM000186/WM000187 serial break rather than treated as universal. The control-piping and operating-control sections identify pre- and post-break hoses and lever components, including differences associated with the suspension seat. Separate sheets cover the standard controls, short-lever setup, and A-F change equipment.

Undercarriage selection is also configuration-specific. Rubber and steel crawler shoe arrangements have their own illustrations and part references. Cab-related coverage distinguishes the standard canopy, TOPS canopy, operator seat and suspension-seat equipment, counterweight, noise-absorbent parts, and the separate operator-room assemblies found in the option section.

The hoe attachment listings distinguish standard and long-arm hardware. Bucket choices include 0.055, 0.08, 0.11, and 0.12 m³ configurations; the 0.08 m³ bucket is identified for the long arm, while the 0.11 m³ group includes standard, reinforced, and hook-equipped versions. Dedicated sheets also cover the blade attachment and its piping.

Optional-equipment coverage extends to spare-port and power-port piping, the cab heater, mirror and light assembly, traction alarm device, and language-specific safety and control nameplate sets. These separate listings help prevent standard-machine parts from being ordered for an option-equipped excavator.

Parts Identification and Change Control

Each illustration uses key numbers that correspond to the adjacent parts list. Asterisks show the assembly hierarchy, while the quantity column normally states the number required for one machine; “AR” is used where the quantity is determined as required. Type and revision indicators distinguish specification changes and newly manufactured versions of an assembly.

The interchangeability symbols show whether a newer part can directly replace the earlier number or whether the two are not interchangeable. Conditional substitutions involving several parts are handled in the notes below the applicable listing. One specific example appears in the Engine & Accessories section, where key items 27, 30, and 38 are identified as interchangeable only together; treating one item as an independent supersession can produce a mismatched mounting set.

Serial applicability is based on the machine’s condition when shipped from the factory. The catalog warns that modifications made later through local service updates are not reflected in those ranges, so an updated machine should be checked against the relevant service information before parts are ordered.

Important Scope Limit

This PDF is a parts-identification catalog, not a service or repair manual. It contains exploded assembly drawings, detailed control-valve section views, component-location illustrations, part numbers, and application data. It does not provide diagnostic flowcharts, circuit-style wiring diagrams, hydraulic pressure-test procedures, torque tables, or removal, disassembly, reassembly, and adjustment instructions.

Heavy undercarriage and swing components and stored hydraulic pressure present serious hazards. Follow the applicable shop isolation and lifting procedures and use the correct service manual for the repair itself; these drawings are intended for parts identification.
