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

This IHI factory parts catalog (P/N Pub. No. 2) covers the IHI 35N mini excavator from serial number WM000001 onward. Keyed illustrations and parts tables identify individual components, assembly quantities, and serial-specific replacements.

PDF Search and Section Bookmarks

Text search and bookmarks help locate components and jump to the main catalog sections. The embedded OCR text can miss part numbers, and some pages have no searchable text. Use the printed parts tables to confirm exact numbers.

The download contains one printable 297-page PDF with English introductory text and English and Japanese parts listings. The page count includes the cover, a repeated preface page, and 37 memo pages.

Undercarriage, Hydraulics, and Attachment Parts

These selected catalog entries show how the parts are organized. Other sections cover items such as the tool kit and traction alarm.

• Undercarriage illustrations distinguish rubber and steel crawler shoes and identify the track adjuster, front idler, upper and lower rollers, and lower traction piping.
• Swing and hydraulic assemblies include the turntable and swing bearing, swing drive, traction and swing motors, rotary joint, oil tank and pump, manifold, control valves, and cylinders.
• Hydraulic lines and operator controls include return and suction piping, swing and traction lines, and separate listings for suspension-seat equipment, short-lever controls, and the A-F change configuration.
• Power-unit and electrical parts include the engine installation, radiator, oil cooler, air cleaner, muffler, oil-pump drive, fuel tank and lines, electrical component layouts, and instrument panel.
• Hoe and blade attachments have separate listings for standard and long-arm hardware, boom-swing parts, attachment piping, and standard, reinforced, and hook-equipped buckets.
• Part-number lookup uses a 19-page numerical index that cross-references part numbers to catalog sheets and illustration keys.

IHI prepared the catalog for parts sales and servicing, where staff use the illustrations and tables to identify the components fitted to a machine.

Serial Breaks and Equipment Options

Check the serial range and installed options together when ordering. The control-piping sheets list separate assemblies for machines with a suspension seat on both sides of the WM000186/WM000187 serial break.

Separate sheets cover the standard canopy, TOPS canopy, operator seat, suspension-seat equipment, counterweight, noise insulation, and optional operator-room assemblies. The boom-cylinder listing also distinguishes the cab and TOPS version. The option section covers spare-port and power-port piping, the cab heater, mirror and light assemblies, and language-specific safety and control nameplates.

Part Numbers and Interchangeability

Asterisks show which parts belong to an assembly, and the quantity column uses “AR” for items supplied as required. Type and revision indicators distinguish equipment configurations and assembly changes.

Interchangeability markings show whether a later part can replace the earlier one. Check the notes before ordering individual replacements. In Engine & Accessories, for example, the brackets at keys 27, 30, and 38 are interchangeable as a group. The serial ranges reflect factory shipments, so check the relevant service updates if the machine was modified later.

Parts Lookup and Service Documentation

Use the exploded views, control-valve sections, and electrical component layouts to identify parts. Consult the applicable service documentation for circuit schematics, diagnostic and pressure tests, torque settings, and repair procedures. Follow shop isolation and lifting procedures when working around stored hydraulic pressure or heavy undercarriage and swing components.

Selected Bucket Sizes and Applications

The hoe bucket listing pairs the 0.055 m³ bucket with a 400 mm width and specifies the 0.08 m³, 500 mm bucket for the long arm.

The 0.11 m³, 600 mm bucket is listed in standard, reinforced, and hook-equipped versions. The 0.12 m³ bucket is listed at 660 mm.
