Part of the New Holland Repair Manuals.
This 348-page New Holland D350 Crawler Dozer Workshop Manual (OEM #604.13.532.00) walks you through every system on the 2005 D350, from the Cummins QSM11 engine down to the final drives. Inside you get full protection tree wiring diagrams, the dozing equipment hydraulic system schematic, and a troubleshooting section covering the converter-transmission group, brake and steering diagnosis display, and undercarriage wear checks. Open to the torque tables and you get real numbers: intake valve clearance at 0.36 mm, exhaust at 0.69 mm, and NBR O-rings rated for continuous duty from -40 to 120°C. No more guessing whether that seal will hold up in your climate or chasing a wiring fault with a test light and a hunch. This PDF carries bookmarks straight to each system, Engine, Transmission, Final Drives, Electrical, so you jump right to the section you need, pull it up on a tablet at the machine, and get your D350 back to work.

New Holland D350 Common Problems This Manual Covers
New Holland D350 engine fails to start or stalls under heavy load with excessive white smoke
Inspect fuel injectors and verify valve clearances. Adjust the intake valve clearance to exactly 0.36 mm (0.014 in) and exhaust to 0.69 mm (0.027 in) as shown on page 48. Replace any degraded O-rings rated for -40 to 120°C if leaks are present.
Manual Section: Engine p. 48Unresponsive dozer blade and sudden loss of hydraulic pressure after routine system maintenance
Perform a flow test in single circuits. Run the engine at 2000 rpm and verify the hydraulic power pump total nominal delivery reaches 380 litri/min. Check the pressure values on page 303 to ensure equipment maximum pressure is maintained at 200 ± 5 bar (2900.7 ± 72.5 psi).
Manual Section: Dozing Equipment Hydraulic System Flow Test p. 303Transmission grinding noises and poor shifting performance when operating in cold weather
Drain the converter-transmission oil and inspect the filters for metal shavings. Review the troubleshooting procedures for stuck valves or wrong viscosity oil. Test the transmission main pressure relief valve and confirm it opens at exactly 16 bar.
Manual Section: Transmission Troubleshooting (General)Slack track chain tension and steep slope wear on the undercarriage shoes
Measure track chain sag and inspect shoe screw tightening. Adjust the track chain tensioner pressure relief valve setting to exactly 689 bar as specified on page 288. Ensure full chain alignment before operating on steep grades to prevent further uneven wear.
Manual Section: Undercarriage Troubleshooting p. 288Frequently Asked Questions
What are the torque specifications for New Holland D350 engine mounting bolts?
The tightening torques for engine mounting bolts vary by size and type. For example, Nut EM16 x 1.5 should be tightened to 47.5 to 52.5 daNm (350.2 to 387.1 lb.ft.), while Self-locking nut (C3) requires 22.5 to 25 daNm (165.9 to 184.3 lb.ft.). Screw TE M10 (C6) has a torque of 6.8 to 6.85 daNm (50.1 to 50.5 lb.ft.). p. 54
What are some common error codes on the New Holland D350?
The New Holland D350 has various error codes for engine and transmission systems. For instance, code 111 indicates internal ECM hardware memory defects, preventing the engine from starting. Code 143 signals low engine oil pressure, leading to progressive power reduction and engine cut-off after 30 seconds if protection is activated. For transmission, code 001 indicates a fault in the left proportional solenoid valve coil. p. 56
How can hydraulic failure be troubleshooted on the New Holland D350?
To troubleshoot hydraulic failure, first check the oil level and inspect filters for clogging. Identify and replace any broken pipes or defective seals causing oil leakages or air suction. If the power pumps are worn or the torque converter safety valve (13) is stuck open, overhaul or replace them as needed. p. 118
Where is the ECU fault code reader located on the New Holland D350?
The ECU fault code reader for the New Holland D350 is referred to as the "BB3 diagnostic tester," identified by part number 380001303. It requires an adapter cable, part number 380001471, for connection. This tool is used for checking the correctness of parameters set by the manufacturer. p. 131
