Kobelco SK200SR / SK200SRLC Hydraulic Excavator Shop Manual (P/N S5YB0001E(3))

• Covers 2000–2002 Kobelco SK200SR and SK200SRLC hydraulic excavators equipped with the Isuzu AA-4BG1 TC engine. It documents the full service specifications across engine, hydraulic, electrical, and structural systems for both standard and long-carriage configurations.
• Official Kobelco publication (P/N S5YB0001E3, first edition, June 2000).
• Contains 917 pages of deep factory specifications, maintenance schedules, and system diagnostic data tailored specifically for the YB01 and LA01 machine series.
• Breaks down standard lifting capacities, attachment dimensions, and crawler ground pressure specs for both 600mm and 700mm shoe variants.
• Serves as the primary reference for the 2000–2002 production run. You get the exact Mechatro control system adjustments required to dial in peak hydraulic performance on the shop floor.
• Outlines complete disassembly and troubleshooting steps for the swivel joint, air-conditioner system, upper structure, and travel motor to fix breakdowns.
• Features essential PDF wiring diagrams, lifting diagrams, boom dimensional drawings, engine characteristic curves, and unit conversion logarithmic charts.

Technical Coverage and Machine Data

The 2000–2002 Kobelco service publication breaks down the core hydraulic excavator systems. Chapters cover general repair precautions, safe machine lifting procedures for different boom-and-arm combinations, and standardized maintenance schedules for the travel system, swing frame, and cab assemblies. It acts as the baseline for technicians conducting routine maintenance, unit disassembly, or system performance inspections. Safety remains a top priority in any shop environment. Always ensure proper personal protective equipment is worn and verify that system pressure is fully relieved before cracking any hydraulic lines or beginning heavy teardowns. Utilizing this reference provides a distinct advantage by supplying the exact thrust clearances and wear limits needed for component rebuilds. You will find step-by-step procedures to rebuild the main control valve, overhaul the swing motor, and service the travel reduction gears—complex jobs that would otherwise require an expensive trip to the dealership.

Specification and Performance Metrics

Expect hard numbers for accurate servicing. The manual details the Isuzu AA-4BG1 TC engine performance characteristics, logging a rated output of 91.9 kW (125 PS) at 2,200 rpm. Fuel injection timing is pinned at 9° before top dead center. Intake valve clearance for the SK200SR sits at exactly 0.4 mm. You will also find hydraulic relief valve settings clearly mapped for various circuits. The main relief pressure operates at 34,300 kPa, while the swing speed for the SK200SRLC is rated at 11 rpm under standard operational parameters. A notorious pitfall when servicing these specific models involves the Mechatro controller "A" adjustment. If a technician attempts this calibration while the engine emergency stop lever knob is pulled out, the engine speed cannot be set properly, leading to erratic performance. Furthermore, skipping the mandatory air bleeding procedure for the hydraulic pump and swing motor after component replacement will rapidly destroy the internal bearings due to cavitation.
