Part of the New Holland Operator Manuals.
All 116 pages of this New Holland 555D, 575D, 655D, 675D Operator Manual PDF (OEM #42055526) focus on one job: keeping your backhoe loader running safely and on schedule. The controls section covers instrument console layouts, key-start procedures, transmission operation, front wheel drive, and ROPS safety guidance. The operations chapters walk you through loader bucket removal, multi-purpose bucket fork work, backhoe controls, digging techniques, and the running-in procedure. Your lubrication and maintenance section maps service schedules from 10-hour daily walkarounds through the first 50-hour service: change engine oil and filter, service the hydraulic filter, and adjust valve clearance. Engine oil filter goes back in at 150 hours; fluid capacities, tire pressures, and operating weights all sit in the specs section. Your machine is down. Get the service interval, skip the guesswork. Jump to any section instantly: it's bookmarked and keyword-searchable on any device.

New Holland 555D, 575D, 655D, 675D Common Problems This Manual Covers
New Holland 555D hydraulic system slow or noisy, loader and backhoe movements feel weak p. 93
Check the hydraulic fluid level at the sight glass and add fluid if low. Inspect the hydraulic filter service indicator and replace the filter at 600-hour intervals per page 93. Check for visible hose leaks before returning to work. Fluid capacity is listed in the Specifications section.
Manual Section: Lubrication and MaintenanceEngine temperature warning light comes on during loader work or heavy digging cycles p. 103
Stop work and idle the engine at low speed. Check coolant level at the overflow reservoir and top up to the capacity listed in your Specifications section. Inspect the radiator face for packed mud or debris and clear it with compressed air. Verify the fan belt has no cracks and sits properly in the groove.
Manual Section: Controls, Instruments and OperationMachine won't start or cranks slowly, battery warning light on after sitting overnight p. 78
Inspect the battery electrolyte level; it should sit 0.25 in. (6 mm) above the separator plates per page 78. Clean corrosion from both terminals with a wire brush and tighten all cable connections at the posts. Confirm the charging indicator light goes out shortly after startup to verify the charging system is working.
Manual Section: Lubrication and MaintenanceEngine loses power under load, black smoke from exhaust, air filter restriction light on p. 83
Remove and inspect the air filter element; replace it every 300 hours or after five dry cleanings per page 83. Tap loose dust from a cleaned element before reinstalling, never wash with water or blow air inward through the filter. Check the pre-cleaner dust bowl and empty it when more than half full. Never operate the engine with the filter removed.
Manual Section: Lubrication and MaintenanceEngine cranks but won't fire after running tank dry or replacing fuel filters p. 95
Prime the fuel system using the hand primer pump before cranking. Pump until you feel firm resistance, then crank. If the engine fires briefly and dies, prime again before the next attempt. Fuel tank capacity is listed in the Specifications section. Inspect both fuel filters at the 600-hour mark per page 95.
Manual Section: Lubrication and MaintenanceFrequently Asked Questions
How do I reset the transmission on a New Holland 555D?
The manual does not describe a specific 'reset' procedure for the transmission. However, if the Transmission Oil Temperature Warning Light comes on, place the transmission in neutral and run the engine at 1000-1200 rev/min until the warning light goes out and the audible alarm no longer sounds, after checking the oil level. This action resolves the condition causing the warning light.
What are the torque specs for a New Holland 655D loader/backhoe?
The manual provides a 'TORQUES' table with various specifications. For example, the Front Wheel Nuts for a 2WD model should be torqued to 130 lbf.ft (176 Nm). Other components like Backhoe Attaching Bolts and Cab/ROPS Attaching Bolts also have specific torque values listed in this table.
What does error code mean on a New Holland 675D?
The manual does not refer to 'error codes' but describes various 'Indicator Warning Lights' on the dash panel. For instance, an 'Engine Oil Pressure Warning Light' indicates that the engine oil pressure has dropped below a predetermined level, and an audible alarm will sound. When such a light comes on while the engine is running, stop the engine and investigate the cause immediately.
