With more than a thousand pages organized into these chapters, the manual gives you the full picture of the SK135SR-3, SK135SRLC-3 and SK140SRL-3. You get dimensional drawings for the boom, arm and bucket, complete hydraulic schematics with colour coding, mechatronic control system diagrams, electrical circuit diagrams, exploded views of the control valve and travel motor, and detailed disassembly/assembly procedures for every major component. The engine section reproduces the Mitsubishi D04EG-TAA service manual, so you have the diesel engine information in the same package.

What This Manual Helps You Do

This Kobelco shop manual is built for the person who actually works on the machine. The specification tables give you the exact dimensions, weights and capacities needed when ordering parts or checking wear. The maintenance chapter lays out standard working times so you can plan a job and quote it properly. The system chapters explain how the hydraulics, mechatronics and electrics interact, which is essential when a fault code appears or when a function behaves differently from the way it should.

The disassembly and assembly chapters cover the upper structure, the attachments and the travel system, with tightening torques noted throughout. When a component has to come apart — a hydraulic pump regulator, a control valve spool, a travel motor, a swing reduction unit — the manual shows the order of disassembly, the inspection points, the wear limits and the reassembly procedure. The troubleshooting chapters let you trace a fault by error code or by symptom, so you can move from a complaint to a repair without guesswork. And the exhaust gas post-cleaning device section covers the DPF system, manual regeneration and the related maintenance standards.

Why Correct Specifications Matter

Hydraulic excavators are unforgiving of wrong clearances, incorrect torque values or contaminated fluid. A pin bushing installed with too much clearance wears quickly and can damage the surrounding structure. A relief valve adjusted beyond its service limit can cause overheating or loss of power. A proportional valve set incorrectly affects the whole machine’s response. This manual gives you the maintenance standards, service limits and adjustment procedures that keep the SK135SR-3, SK135SRLC-3 and SK140SRL-3 working within specification.

For owners and fleet managers, having the shop manual on hand reduces downtime. Instead of waiting for a dealer technician or relying on memory, the mechanic can look up the correct procedure, confirm the torque, check the wear limit and get the machine back into service.
