What This Shop Manual Delivers

The Kobelco SK330-8 and SK350LC-8 are 33–35 tonne-class hydraulic excavators built around the HINO J08E-TM six-cylinder turbo-intercooled diesel engine. This manual goes far beyond a basic owner’s handbook. It documents the machine’s hydraulic architecture — twin variable-displacement axial piston pumps with electronic flow control, a gear pump for pilot circuits, an eight-spool main control valve, swing and travel motor assemblies, and the full mechatronics control layer that governs unload valves, pump displacement, travel straight, swing priority, and boom/arm/bucket conflux.

For the technician, the value lies in the depth of the disassembly and assembly sections. The manual walks through removing and installing the boom, arm, bucket, cylinders, swing motor unit, travel motor, reduction unit, swivel joint, control valve, hydraulic pump and regulator — with tightening torques, shim adjustment procedures, and maintenance standards at every step. The troubleshooting chapters cover both error-code-driven faults (via the mechatronics controller self-diagnosis) and symptom-based diagnosis, so you can trace a problem from a displayed error code through to the failed component.

Engine coverage is equally complete: the HINO J08E-TM workshop manual section covers cylinder head overhaul, piston and connecting rod replacement, crankshaft inspection, camshaft and timing gear, valve system adjustment, fuel system (supply pump, common rail, injectors), EGR, cooling, lubrication, turbocharger, starter and alternator — with standard values, repair limits, and tightening torques throughout.

Who This Manual Is For

• Hydraulic excavator service technicians performing scheduled maintenance or repairs
• Heavy equipment workshops maintaining a fleet of Kobelco SK330-8 or SK350LC-8 machines
• Machine owners who want to understand fault codes and system operation before authorising repairs
• Technical trainers and students studying Kobelco excavator systems
• Anyone needing the HINO J08E-TM engine workshop manual for the same machines

Why This Manual Matters

Hydraulic excavators are high-value assets, and incorrect repair procedures or guessed specifications can lead to component damage, reduced service life, or unsafe operation. This manual provides the measured values, clearances, tightening torques, and step-by-step procedures needed to do the job correctly. The mechatronics diagnostics are especially valuable — the controller stores error codes for pressure sensors, proportional valves, solenoids, and communication faults, and this manual explains what each code means and how to test the affected circuit.

The maintenance time table also gives flat-rate guidance for planning service work, and the standard maintenance time list for the engine helps estimate job duration.
