Part of the New Holland Repair Manuals.
Chopping season won't wait on a slipping cutterhead clutch or a metal detector that trips on nothing, and this New Holland FP230, FP240 repair manual PDF answers both across 598 factory pages under OEM number 86900645. Wiring diagrams anchor an electrical section that fills nearly half the book, tracing circuits on Metalert III units and non-detector machines, backed by troubleshooting charts that walk you from symptom to the failed relay or harness connector. Driveline coverage runs just as deep: tractor PTO repair, bevel and reversing gearboxes, electric clutch testing, cutterhead knife replacement, shear bar adjustment, and feed roll rebuilds. Set blower paddle clearance between 0.76 and 1.0 mm, and pull cutterhead knife bolts to 237-271 N·m (175-200 ft.-lb.). A guessed knife bolt figure turns a spinning cutterhead into shrapnel. Bookmarks drop you on the exact procedure in seconds, so the repair fits inside the weather, not the other way around.

New Holland FP230, FP240 Common Problems This Manual Covers
New Holland FP230 haylage plugs at the blower inlet, auger bolt shears, blower housing runs hot
Pull the sheared bolt and inspect the cross auger flighting; replace it once worn below 6.4 mm (1/4 inch) thickness. Set paddle end clearance to 0.76 to 1.0 mm so material cannot pinch between the paddle and housing. Check the blower slip clutch, set at 746 to 881 N·m, then start the auger procedures on page 549.
Manual Section: Ejection p. 549Lower metal detector feed roll bearings fail repeatedly, roll wobbles and self-destructs mid-season
Replace the roll and measure shaft-to-hub runout against the 0.25 mm (0.010 inch) limit on page 476 before reinstalling. Torque the hub bolts to 15-22 N·m. If the stub shaft was bent, check clearance between the smooth roll and bottom front feed roll after installation; anything over 3 mm (1/8 inch) lets material wedge between the rolls and restart the failure.
Manual Section: Product Feeding p. 476Chopper plugs in heavy corn silage, cutterhead bogs down and won't maintain throughput
Inspect the knives and shear bar before anything else; dull knives can double the power the cutterhead pulls. Regauge or replace worn knives and torque the knife bolts to 237-271 N·m (175-200 ft.-lb.) per page 495. Run the sharpener with the stone set 36 mm (1-7/16 inch) below the carrier, then slow ground speed in wet, heavy windrows.
Manual Section: Chopping p. 495Header creeps down in transport, attachment lift cylinder leaks oil at the rod
Remove the lift cylinder and reseal it. Replace the rod and piston seals, inspect the rod for scoring, and torque the piston nut to 210-250 N·m (155-185 ft.-lbs.) per the spec on page 186. Cycle the header several times, recheck for drift, and confirm it holds before you head back to the field.
Manual Section: Hydraulics p. 186Frequently Asked Questions
What are the torque specifications for the cutterhead knife bolts on the FP230 and FP240?
The torque specification for the knife bolts on the cutterhead is 237-271 N⋅m (175-200 ft.-lb.). p. 35
How do I reset a fault code on the Metalert III metal detector system?
Fault codes are reset by turning the power off. If the fault persists, the system will display the code again upon power-up. p. 348
What is the oil capacity for the 97° gearbox?
The oil capacity for the 97° gearbox is 3.8 liters (4 quarts). p. 78
What is the required torque for the lift cylinder piston nut?
Tighten the lift cylinder piston nut to 210 to 250 N⋅m (155 to 185 ft.-lbs.). p. 186
What is the correct tire pressure for the harvester?
The recommended tire pressure for all tires on the harvester is 200 kPa (30 psi). p. 35
