Excavator System Coverage

This manual breaks down the complete layout of hydraulic circuits and electrical systems for the SK25SR-2. It maps out the operational logic of travel controls, bucket and arm digging circuits, and boom lift mechanisms. Mechanics will find specific documentation for dismantling and assembling major components, including the slewing motor, hydraulic pump, and undercarriage roller assemblies. It delivers the exact factory-specified performance metrics needed to evaluate the travel motor and dozer blade cylinder in a professional shop environment.

Technical Specification Preview

Shop technicians get direct access to performance inspection tables detailing hydraulic pressure settings, timing values, and oil flow diagnostics. The intake valve clearance for the Yanmar 3TNE74-NYBB engine, for instance, is listed at 0.2 mm. Main circuit hydraulic relief pressure stands at 230 kgf/cm² (3270 psi), while the swing motor drain rate is specified at 4.2 liters per 30 seconds. A comprehensive unit conversion chart is also included to verify pressure and force metrics during field testing. Always rely on the complete OEM documentation and qualified heavy equipment technicians before executing any physical maintenance or adjustments to ensure workplace safety and machine integrity.
