Component and System Documentation

When you are tearing down complex upperstructure components, guesswork isn't an option. This documentation provides deep-dive breakdowns of the main pump device, clearly mapping out both the variable displacement piston pump assembly and the fixed displacement pilot gear pump.

Troubleshooting the control valve? The manual lays out both three-spool and four-spool configurations, accurately identifying relief valve operations, surge suppression mechanisms, and variable pressure compensation logic.

Hydraulic and Operational Specifications

Working on heavy machinery hydraulic systems involves extreme pressure. Always verify the specified load-sensing control values before initiating diagnostic tests to ensure absolute shop safety and prevent equipment damage.

Having the correct numbers on hand speeds up any overhaul. This publication details exact service refill capacities for the main hydraulic system, swing reduction gears, and engine cooling systems. Hydraulic pressure monitoring is thoroughly documented via the P-sensor and DP-sensor, providing precise output reference values.

If you are doing a deep engine teardown, the rebuild specs list critical tolerances like the 0.03–0.12 mm piston-to-cylinder clearance for the engine block. You will also find highly specific operational baselines, including the swing dampener relief setting at 25.5 bar (370 psi) for neutral conditions and the exact coolant anti-rust agent volume (420 cc per mix).
