Part of the New Holland Repair Manuals.
This 945-page New Holland E Series Backhoe Loader Service Manual covers the 555E, 575E, 655E, and 675E, cross-referenced to OEM numbers 9624515DS, 9624666DS, and 9624714DS. You get full wiring diagrams for lights, starting, and charging circuits, plus hydraulic schematics covering the loader control valve, backhoe control valves, and swing system. Inside, a dedicated fault code section walks the Powershift Transmission and torque converter, backed by page after page of troubleshooting steps for engine, fuel, and rear axle systems. The rear steering pump puts out 16.6 GPM (62.7 L/min) at 2200 RPM and 1500 psi when new; check clutch pack clearance against the 2.79-5.21 mm spec before reassembly. Forum guesses won't get your backhoe back in the trench. This PDF carries bookmarked navigation, so you jump straight from cover to hydraulic kit installs without hunting through 945 pages by hand.

New Holland 555E, 575E, 655E, 675E Common Problems This Manual Covers
New Holland 555E hydraulic system loses pressure after 10 hours, no loader or backhoe movement
Check page 807's troubleshooting chart for all-circuits-fail conditions first: pump drive inoperative, low oil level, or restricted suction line. Verify reservoir is full and inspect the suction line for collapse or air leaks. Pull the pump and test output against the 30-38 ft. lbs. (41-51 N·m) mounting bolt torque on page 724; if efficiency reads below 80%, replace the pump.
Manual Section: Hydraulic System Troubleshooting p. 807Engine stalls under heavy load with white smoke from exhaust after 15 hours of operation
Pull the injectors and check nozzle opening pressure against the 3480-3590 psi (209-247 bar) spec on page 124. Inspect needle valves for bluing or scoring; per page 146, any damaged or blued needle valve gets discarded and replaced as a matched set with the nozzle body, never reused. Bleed air from the fuel lines and torque the injector retaining nut to 35 ft. lbs. (48 N·m) before restarting.
Manual Section: Fuel System - General Troubleshooting p. 121Transmission jumps out of gear with grinding noise during heavy digging
Drain the transmission and inspect the clutch pack clearance against the specs on page 446: forward low and reverse should read 2.79-5.21 mm, first and second 2.54-5.41 mm. Check friction discs and clutch plates per page 339, if any disc shows discoloration or warping, replace it rather than reuse it. Refill with the correct 4.75 gallon (18 liter) capacity on 4WD units and verify the shift mechanism engages cleanly before road testing.
Manual Section: Transmission (4x4 Power Shuttle) TroubleshootingEngine won't crank or cranks slowly, charge indicator lamp stays lit
Test battery output against the CCA rating for your model (800 CCA/100 AH on the 555E, 960 CCA/132 AH on 575E, 655E, and 675E) before condemning the starter. Clean and tighten all ground connections and check the starter solenoid for a weak pull-in. Verify alternator output at idle and under load; a charge lamp that won't clear after a good battery test usually points to the alternator or its wiring harness.
Manual Section: Electrical System - Wiring, Lights, and Controls TroubleshootingSteering wanders or requires excessive effort at low RPM
Connect a gauge to the steering circuit and check standby pressure against the 101 psi (7 bar) spec on page 596. Low readings point to a worn steering pump or a sticking priority valve; inspect the pump inlet screen for debris before pulling the unit. If cylinder seals show weeping or scoring during teardown, replace all of them per page 613 rather than reusing any single seal.
Manual Section: Steering Troubleshooting p. 595Frequently Asked Questions
What are the torque specifications for New Holland 555E engine bolts?
The torque specifications for various engine bolts are provided. For instance, Main Bearing Bolts should be tightened to 145 ft. lbs. (197 N·m), Connecting Rod Bolts to 110 ft. lbs. (149 N·m), and Cylinder Head Bolts (with Engine Cold) to 160 ft. lbs. (217 N·m). The Oil Pan Drain Plug requires a torque of 30 ft. lbs. (41 N·m). p. 63
What error codes indicate hydraulic failure on New Holland 655E?
Fault codes F5, F6, F7, F8, F9, and F10 indicate issues related to the powershift transmission's hydraulic control system. Specifically, F5 and F6 relate to open circuit direction outputs, F7 and F8 also indicate open circuit direction outputs, and F9 and F10 point to modulation output short or open circuits, all of which are critical for hydraulic function. p. 434
What is the engine oil capacity for a New Holland 4-cylinder engine with an oil filter?
The engine oil capacity for a New Holland 4-cylinder engine, when including the oil filter, is 17.6 U.S. Qts, which is equivalent to 14.8 Imp. Qts or 17.0 Liters. This specification is important for proper engine lubrication and maintenance. p. 61
What is the cooling system capacity for a New Holland 4-cylinder engine?
The cooling system capacity for a New Holland 4-cylinder engine is 6.2 U.S. Gals, which translates to 5.2 Imp. Gals or 24 Liters. It is recommended to use a solution of 50% clean water and 50% recommended antifreeze with 5% corrosion inhibitor. p. 62
