This 699-page New Holland 3910 Parts Catalog PDF focuses on one job: finding the exact part number for your 1983-1990 three-cylinder ag tractor without guesswork. It pairs parts lists with exploded views covering everything from the synchronized 8-speed transmission and independent PTO to the hydraulic lift cylinder, remote control valves, power steering pump, and full LH/RH electrical system. Cab components get serious depth too: the low-profile cab glass, doors, rollbar, heater, and seat assemblies are all mapped out. Factory dimensions confirm you're ordering the right piece: the lift-and-drop hose assembly measures 30-1/4 inches (768.35mm) and the long hydraulic hose run comes in at 118 inches (2997.2mm). Wrong part, second freight charge, machine still down. Bookmarked by section and keyword-searchable, so you find the figure, pull the part number, and place one order.

New Holland 3910 Common Problems This Manual Covers
New Holland 3910 hydraulic lift cylinder seal kit number unclear, two part options listed p. 155
Open the Hydraulic Lift System exploded view and locate the lift cylinder assembly on page 155. The unload bushing clearance spec is 25.405/25.410mm, which determines whether you need the standard or oversize seal kit. Match the bushing bore measurement to the correct part number in the adjacent parts list, then verify against your serial number range in the index.
Manual Section: Hydraulic Lift SystemHydraulic hose assembly part number for the lift and drop circuit, length unknown p. 187
Find the hydraulic hose exploded view starting on page 187. The Lift & Drop hose assembly measures 30-1/4 inches (768.35mm), and the main system hose assembly runs 118 inches (2997.2mm) per page 188. Match your hose routing and connection type to the correct part number in the assembly diagram before ordering.
Manual Section: Hydraulic Lift SystemBattery replacement part number and capacity spec, two options listed in the electrical section p. 459
Check the Battery & Support Assembly section on page 459. Two options are cataloged: a standard 80 A.H. unit and a dry-charged variant rated at 810 CCA. Confirm your tractor's electrical configuration matches the correct capacity, then cross-reference the support bracket part numbers on the same page to order a complete replacement kit.
Manual Section: Electrical System & LightingClutch disc part number unclear, two different disc sizes appear in the transmission section p. 307
Locate the clutch assembly exploded view on page 307, which lists the 11-inch disc assembly. For the main transmission clutch, cross-reference page 309, where the 13-inch clutch disc is cataloged separately. Match the disc diameter to your specific configuration, then verify the part number against the PTO Clutch Linkage section to confirm correct fitment.
Manual Section: Transmission & PTOAir cleaner assembly part number uncertain, filter dimensions not obvious from the exploded view p. 364
Pull up the Air Cleaner Assembly diagram on page 364, which catalogs the 6-inch primary filter element. Confirm the mounting bracket configuration matches your hood setup before ordering, since early and late production units used different mounting positions. The parts list adjacent to the diagram separates the primary element, safety element, and body assembly as individual line items.
Manual Section: Fuel SystemAlternator part number for a US-market replacement, amperage rating not confirmed before ordering p. 473
Locate the Alternator Assembly section on page 473. The US-market unit is rated at 51 amps, listed separately from export variants on the same page. Match your current alternator mounting bracket pattern to the exploded view to confirm the correct assembly part number, then cross-reference the wiring connector in the Electrical System section before finalizing the order.
