IMAGES PREVIEW

What This Manual Provides

This Kobelco SK35SR-6 Hydraulic Excavator Shop Manual is the complete technical documentation set for the SK35SR-6 and SK35SR-6E mini excavators. At 1050 pages, it covers every system on the machine in the depth a professional technician needs — from the Yanmar 3TNV82A-B engine through the hydraulic pump, control valve, swing motor, travel motor, and all electrical and mechatronic components.

The manual opens with full machine specifications: dimensions, working ranges, component weights, engine performance curves, bucket and crawler shoe options, and transportation data. From there it moves into the maintenance and testing standards, giving you the measured values, service limits, and adjustment procedures required to keep the machine within specification. The hydraulic system chapter explains the complete circuit operation — neutral, travel, swing, bucket, boom, arm, boom swing, dozer, and combined operations — with color-coded circuit diagrams that show exactly how oil flows through the system in each mode.

For electrical work, the Kobelco SK35SR-6 shop manual contains the full electric circuit diagram and harness layouts for every configuration: cab and canopy, air conditioner, expansion controller, quick hitch, thermo switch, boom light, and cab light. The component system chapter provides detailed construction and operation information for every major hydraulic and electrical component, while the air conditioner section covers the complete HVAC system from basic refrigeration cycle through troubleshooting.

When it comes time to disassemble, the manual walks through removal and installation of every major assembly — canopy, cab, counterweight, pump, control valve, fuel tank, hydraulic oil tank, radiator, engine, swing motor, swivel joint, upper frame, travel motor, crawler, rollers, idler, sprocket, and swing bearing — with torque values, tool requirements, and step-by-step procedures. The attachment section covers bucket, quick hitch, arm, boom, boom swing, and dozer removal and installation, plus complete cylinder disassembly and reassembly with maintenance standards and jig lists.

The troubleshooting chapters are organized by symptom and system. The hydraulic troubleshooting section uses flow charts to trace problems in attachment, travel, swing, and pump operation. The electrical troubleshooting section covers starting, horn, working lights, hourmeter, fuel gauge, water temperature, travel speed change, and deceleration circuits. Engine troubleshooting addresses starting problems, rotation issues, output loss, exhaust problems, and fuel/oil consumption. For machines equipped with the mechatronic controller, the optional troubleshooting chapter decodes error codes from the self-diagnosis system and provides repair actions for each.
