Part of the New Holland Repair Manuals.
On the New Holland EH215 crawler excavator, pump control, boom and arm flow merging, recirculation, travel straight and swing priority all depend on sensors and proportional valves. This book covers self diagnosis and service diagnosis for that system, plus sensor and proportional valve checks.
The rest of the book has the colour-coded hydraulic circuit diagram and three electrical circuit diagram sheets. It also has the performance inspection chart and the removal and teardown of the attachments, cylinders, upper structure and travel system. The Mitsubishi 6D34-T engine shop manual is in there too. This is CNH America Form Number 6-75780NA, issued January 2004.

New Holland EH215 Common Problems This Manual Covers
No operation is possible
First check for 24 V at the lever lock solenoid connector. If it is missing, go to the electrical troubleshooting. Next, check that pilot pump primary pressure is about 50 kgf/cm² (710 psi). If it is low, adjust or replace the pilot pump and pilot relief valve. Then check the pilot valve inlet pressure.
Manual Section: Hydraulic Troubleshooting p. 732All attachment motions are slow
With the key on and the engine stopped, check the back pressure sensor and the P1 and P2 negative control sensors. Replace any faulty sensor. Check the pump proportional valve currents, then the negative control block. Confirm pilot pump primary pressure of 50 kgf/cm² (710 psi), otherwise check or replace the pilot pump and relief valve. Finish with the main relief pressure.
Manual Section: Hydraulic Troubleshooting p. 734Swing motion does not work
Unplug the swing parking brake release solenoid connector. If the machine then swings, go to the electrical troubleshooting. Otherwise check the solenoid secondary pressure, the swing pilot pressure sensor, the swing parking brake solenoid and the proportional valve. Check swing pilot valve secondary pressure in both directions. If it is wrong, check or replace the orifice or pilot valve.
Manual Section: Hydraulic Troubleshooting p. 752Starter does not run when the key is turned
Check battery voltage, electrolyte level and specific gravity, then charge or replace the battery. If 24 V is at terminal A of the battery relay but not at A1, replace the 60 A fusible link. Check the 20 A key switch fuse and the wiring and connectors to the key switch. Then check terminals M and ST of the key switch and the starter relay feed in START.
Manual Section: Engine Troubleshooting p. 788Frequently Asked Questions
Does this manual cover my New Holland EH215 excavator?
Yes. It is the New Holland EH215 crawler excavator service manual, CNH America Form Number 6-75780NA, issued January 2004. The book states 'SK210LC is NEW HOLLAND Model EH215' and gives specifications for the SK210-VI and SK210LC-VI. The electrical circuit diagrams are marked for serials YN07-30001~ and YQ07-03501~. p. 6
What engine is in the New Holland EH215, and what are the oil and coolant figures?
It has a Mitsubishi 6D34-TEB. That is a six-cylinder, 4-cycle, water-cooled, direct injection turbocharged diesel of 5861 cc, with 104 x 115 mm bore and stroke. It is rated at 107 kW (144 Hp) at 2,000 rpm. Use API CD or better oil: 18 L in the pan and 1.1 L in the filter. The engine main body alone holds 9.5 L of coolant. Cold valve clearance is 0.4 mm on both intake and exhaust. p. 35
What are the New Holland EH215 hydraulic pressures?
The K3V112DT main pump delivers 210 (55) x 2 l/min (gal/min). It is rated at 350 kgf/cm² (4980 psi), or 385 kgf/cm² (5470 psi) with boost. Pilot circuit primary pressure is 50~55 kgf/cm² (710~780 psi). Swing motor relief is set at 285 kgf/cm² (4050 psi). The engine speed checks give low idle 950~1025 RPM, A-Mode 1925~1975 RPM and B-Mode 2195~2245 RPM. p. 337
How heavy is the EH215, and how fast does it travel and swing?
Working weight runs from 20,500 kg (45,200 lbs) on 600 mm shoes to 21,500 kg (47,000 lbs) on 900 mm shoes. Ground pressure drops from 0.43 (6.11) to 0.30 (4.27) kg/cm² (psi) across that range. Travel speed is 6.0 km/h (3.7 mph) in fast mode and 4.0 km/h (2.5 mph) in slow mode. Swing is 11 RPM in M-Mode at high idle, and gradeability is 70% (35 degrees). Bucket digging force is 13 664 kgf (30,000 lbf) with power boost. p. 31
What is inside this manual: circuit diagrams, troubleshooting, disassembly?
All three. You get three electrical circuit diagram sheets and a hydraulic circuit diagram. The hydraulic diagram has colour-coded neutral, travel, bucket, boom, swing and arm circuits. Mechatro self diagnosis and service diagnosis are covered, along with the performance inspection chart and adjustments. Removal and disassembly cover the attachments, cylinders, upper structure and travel system. There are troubleshooting flow charts for Mechatro, hydraulics, electrics and engine, and the Mitsubishi 6D34-T engine shop manual closes out the book. p. 208
