Technical Coverage and System Data

The Kobelco SK30SR-2 and SK35SR-2 shop manual documents technical performance standards, operational parameters, and maintenance procedures for the mini excavator series. Detailed chapters outline machine specifications, including engine data for the Yanmar 3TNE82A series, hydraulic circuit functionality, and standardized testing procedures for travel and slewing performance. The text provides a technical breakdown of system pressures, clearances, and tolerances for the boom, arm, bucket, dozer, and swing mechanisms, serving as a technical reference for qualified mechanics performing maintenance or component overhaul.

Engineering Specifications and Testing Values

Specification data within the manual provides a deep look into the operational requirements of the SK30SR-2 and SK35SR-2 excavators. Main circuit pressure is documented at 230 kgf/cm2 (3270 psi) for optimal boom, bucket, and travel performance. The what an OEM service publication covers includes torque tables for capscrews and nuts, ranging from M6 to M36, formatted for both lubrication and non-lubrication scenarios. Coolant system capacity is specified at 2.5 liters, with engine oil capacity listed at 3.9 liters total. Slew bearing play is categorized by strict clearance limits of 1.4 ± 0.4 mm to ensure structural integrity during rotation.
