New Holland MH City, MH Plus, MH 5.6 Common Problems This Manual Covers
New Holland MH excavator hydraulic system loses pressure and power under load, oil leaking near pump
Check the load-limit regulator function on page 720; it balances pump power absorption against engine output, so a mismatch points to worn pump seals or contaminated fluid. Replace O-rings and seal rings per page 17 whenever hydraulic lines are opened, never reuse them. Verify by-pass filter calibration reads 2 bar (29 psi) on page 64, and confirm system pressure stays under the 7 bar (102 psi) maximum on page 87 before condemning the pump.
Manual Section: Electronics - Power Control System p. 720Engine overheats during continuous operation in high ambient temperatures, radiator fins clogged with debris
Check coolant temperature against the 50°C reference point on page 137 before assuming a fan or thermostat fault. Inspect radiator fins for packed debris and clean with low-pressure air or water, not a scraper. Never check or adjust the fan belt with the engine running, per the warning on page 15. Review the fan motor revolutions logic on page 720, since the load-limit regulator adjusts fan speed off turbocharger, coolant, and hydraulic oil temperature.
Manual Section: Upper Structure - Multi-Cooler p. 137Machine won't restart after hydraulic pressure engagement during maintenance, safety sensor lockout tripped
Confirm hydraulic pressure is fully disengaged before restarting; the E04 safety sensor code locks out the starter until residual pressure drops to zero. Bleed air from the hydraulic system per the procedure on page 104, then verify pilot control pressure reads normally at start-up per the reference on page 35. Cycle the key off for 30 seconds and recheck the troubleshooting procedures on page 87 before attempting a second start.
Manual Section: Upper Structure - Service Procedures p. 104Hydraulic fluid filter clogs quickly, oil flow restricted and system slow to respond
Pull the hydraulic fluid filter and inspect the element for metal particles or heavy sediment; replace it if the by-pass valve trips below the 2 bar (29 psi) setting on page 64. Confirm system operating pressure stays under the 7 bar (102 psi) maximum specified on page 87. Drain visibly contaminated fluid, refill with clean oil, and shorten the filter change interval if debris returns within one service cycle.
Manual Section: Hydraulic System p. 64Turret rotation grinds or binds when slewing under load, bearing bolts loosening over time
Check the torque specification chart for slewing bearing hardware; the exact M16 torque figure is model-specific on page 89, so confirm which MH variant you're servicing before torquing. Verify rotation speed at maximum pressure does not exceed 2900 rpm as listed on page 84, since sustained over-speed accelerates bearing wear. Inspect the raceway for pitting, clean the mounting face, and retorque bolts in a criss-cross pattern across two passes.
