What This Manual Covers

The New Holland MHCity MHPlus MH5.6 Hydraulic Excavator Workshop Manual (604.13.557) is a 687-page technical repair reference written for service technicians working on these three closely related wheeled excavator models. Each model shares a common architecture but differs in working equipment configuration — the MHCity is sized for urban and city environments, the MHPlus is a heavier-duty variant, and the MH5.6 is the largest of the three — and the manual addresses all three in parallel throughout, with model-specific data clearly differentiated wherever dimensions, cylinder data, travel motor specifications, or tyre tables diverge.

Across its 687 pages this manual gives a service technician the technical foundation to perform virtually every repair and calibration task on the New Holland MHCity, MHPlus, and MH5.6 — from diagnosing an ESX fault code through the multifunction display, to fully dismantling and rebuilding boom, stick, and bucket cylinders, to calibrating twin pump demand curves and slewing pump zero position. The depth of the hydraulic and electronics coverage is particularly strong: full schematic circuit diagrams are included for every hydraulic circuit variant, and the electronics section traces signal flow from joystick input through CAN bus to proportional valve activation. No engine rebuild procedures are duplicated here — the manual references the engine manufacturer’s own documentation for internal engine work — but all machine-side engine interaction, including engine speed sensing, PCS load-limit regulation, and coolant/charge-air temperature integration, is fully covered.

What You Can Do With This Manual

With the New Holland MHCity MHPlus MH5.6 Workshop Manual 604.13.557 a qualified technician can troubleshoot hydraulic faults using schematic diagrams and fault codes, calibrate the ESX and PCS control systems to factory parameters, remove and rebuild every hydraulic cylinder in the working equipment, repair axles, gearboxes, and the slewing ring, overhaul the hydraulic control block, and carry out structural superstructure and undercarriage repairs. Using correct manufacturer procedures and specified tightening torques prevents unnecessary damage and ensures machine safety after repair.
