Chapters Covered

The workshop manual is organized into five main sections, each addressing a major area of the machine:

• Section 1: General
• Section 2: Upperstructure
• Section 3: Undercarriage
• Section 4: Front Attachment
• Section 5: Engine

Section 1 – General

This section establishes the foundational procedures used throughout the manual. It covers precautions for disassembling and assembling, including cleaning and inspection protocols, tool preparation, and handling of hydraulic systems. Tightening torque specifications are provided for standard bolts, piping joints, and split flange connections. The section also includes painting specifications and the procedure for bleeding air from the hydraulic oil tank, which is a prerequisite for many of the service operations described later in the manual.

Section 2 – Upperstructure

This is the largest section of the manual, covering every major component mounted on the excavator’s upper frame. Groups include the cab, counterweight, main frame, pump device, control valve, swing device, pilot valve, pilot shut-off solenoid valve, shockless valve, solenoid valve unit, and engine. Each group provides removal and installation procedures, disassembly and assembly steps, component structures with exploded views, and maintenance standards. The pump device group covers the main pump assembly with detailed exploded diagrams and torque specifications for the casing, cylinder block, valve plate, and gear pump. The control valve section documents the housing, spools, relief valves, and solenoid valves with sectional views and assembly torque values.

Section 3 – Undercarriage

The undercarriage section covers the swing bearing, travel device, center joint, track adjuster, front idler, upper and lower rollers, and tracks. Each component group includes removal, installation, disassembly, assembly, and maintenance standard information. The travel device section is particularly detailed, covering the travel motor, brake valve, planetary reduction gears, and sprocket with exploded views and measurement specifications. The track adjuster group includes special tool requirements and step-by-step assembly procedures with spring compression specifications.

Section 4 – Front Attachment

This section addresses the front attachment assembly and the hydraulic cylinders. It begins with the hydraulic circuit pressure release procedure, then covers removal and installation of the complete front attachment. The cylinder group provides detailed disassembly and assembly procedures for the boom cylinder, arm cylinder, bucket cylinder, boom swing cylinder, and blade cylinder. Each cylinder section includes seal replacement, torque specifications, and special tool requirements. Maintenance standards for pins, bushings, and cylinder components are also provided.

Section 5 – Engine

The engine section covers the 4LE2 ISUZU diesel engine used in the ZX85USBLC-3. It includes general information, service precautions, function checks, specifications, and complete mechanical procedures for the engine. Topics include the rocker arm shaft, cylinder head, piston and connecting rod, flywheel, crankshaft front and rear oil seals, timing gear train, camshaft, crankshaft, and cylinder block. Supporting systems are also covered, including cooling, fuel, electrical, exhaust, lubrication, intake, and preheating systems. The fuel system section includes injection pump and governor procedures, while the electrical section covers the charging system and starter.

What This Workshop Manual Enables You to Do

This Hitachi ZX85USBLC-3 workshop manual supports a wide range of maintenance, repair, and diagnostic tasks. You can use it to perform scheduled maintenance, remove and install major components, disassemble and reassemble hydraulic pumps and motors, rebuild cylinders, service the undercarriage, and troubleshoot system faults. The manual provides the torque values, clearances, wear limits, and adjustment specifications required to complete these jobs to the manufacturer’s standards.

For technicians and equipment owners, having the correct procedures and specifications matters. Incorrect tightening torque can damage components or cause leaks. Improper assembly can lead to premature failure. Missing a wear limit can result in a breakdown in the field. This manual removes the guesswork by providing the data and step-by-step procedures needed to do the job right the first time.

All procedures are illustrated with exploded views, sectional diagrams, and component photographs where applicable, making complex assemblies easier to understand. The manual also includes maintenance standard tables with nominal dimensions, service limits, and repair procedures for worn components.
