1983–1990 Ford 3910 3-Cylinder All-Purpose Tractor Parts Manual

This Ford 3910 parts manual covers the 1983–1990 three-cylinder All Purpose agricultural tractor. Related Ford model codes identify shared assemblies; applicability follows the individual figure and parts-list entry.

Text search and navigation: Parts descriptions, part numbers, figure titles and the index are searchable. Bookmarks open the search guide, index, catalog and reference sections. Callout numbers within drawings are not searchable.

• Engine assemblies: Illustrated parts listings for gas and diesel engines, with separate internal assemblies, gasket kits and replacement-component notes.

• Transmission and PTO: Parts breakdowns for synchronized and non-synchronized transmissions, clutch controls, live and independent power take-offs, and creeper gear kits.

• Axles, wheels and steering: Front and rear wheel assemblies, axle housings, differential-lock linkages, manual steering gears, and power-steering pumps and cylinders.

• Hydraulics and hitch equipment: Lift covers, cylinders and linkage, remote control valves, pump assemblies, swinging drawbars and automatic pick-up hitches.

• Fuel and cooling: Rotor fuel-injection pumps, injectors, carburetor assemblies, fuel filters, diesel cold-start equipment, radiators and water-pump component listings.

• Electrical and cab parts: Wiring-harness layouts, lighting components, instrument clusters, starters, alternators, low-profile cab hardware and rollbar safety frames.

Suited to mechanics and experienced owners who can identify their tractor’s installed assemblies and use illustrated parts lists to plan repair work.

Engine Parts and Replacement Notes

Engine entries separate cylinder blocks and heads, crankshafts, camshafts, pistons and connecting rods. Replacement-block notes identify stepped studs and head bolts associated with particular block versions; bearing listings distinguish engine build codes and service sizes.

The Fuel Injection Pump (Rotor) illustration identifies internal head-and-rotor components and related hardware. Single and dual fuel filters have separate listings. Water-pump drawings break out housings, impellers and seal components.

Transmission, PTO and Axle Variants

Transmission drawings distinguish the eight-speed synchronized and non-synchronized units and H-pattern shift hardware. The 8-Speed Synchronized Transmission Gears figure identifies shafts, gears and synchronizers. Live PTO with a double clutch and independent PTO have separate assembly breakdowns.

Front-drive drawings distinguish AE1-159 and AE1-121 axle groups. Ring Gear & Pinion Assembly and Swivel Housings & Steering Arms figures cover their associated components. Rear-axle, differential and differential-lock linkage listings identify the corresponding housings and hardware.

Hydraulic Lift, Pumps and Remote Controls

Hydraulic Lift Cylinder & Related Parts breaks out the cylinder, valve assemblies, seals and internal hardware. Engine-mounted gear pumps, center-housing pumps and dual-pump attachment components are separated.

Remote-control listings distinguish single- and double-spool valves, couplers and cab-mounted handles. Hydraulic trailer brakes and lift-assist rams have their own entries. These distinctions help match the installed pump and valve arrangement before ordering parts for a hydraulic repair.

Wiring Layouts and Cab Equipment

US and NH-E electrical-system figures show harness and component locations. Rear Wiring (W/Stop Lamps & Flasher) covers rear harnesses, lighting connections and associated hardware. These are parts-layout drawings, not circuit schematics or electrical troubleshooting charts.

Instrument-cluster assemblies have itemized component drawings. Low-profile cab listings separate roof and heater versions, glazing, doors and wipers; inner-roof/heater applicability follows the cab serial breaks listed above.

Wheel Hardware and Parts Compatibility

Wheel coverage includes standard and power-adjustable rear wheels, manual-adjust wheel weights and front wafer weights. The rear-wheel disc supersession note distinguishes tapered-hole and straight-hole discs and their matching nuts and washers, helping identify the hardware needed with a replacement disc.

The hardware-conversion appendix excludes mixing metric and inch threads in tapped holes or nut-and-bolt joints. Such mismatches can damage fastener or housing threads.

Parts Identification and Repair Scope

This catalog supports component identification and repair planning. Exploded views show how parts relate; they do not supply overhaul sequences, torque tables or adjustment procedures. References to service bulletins identify separate documents rather than reproducing their instructions.

Reference only — always consult a certified technician before performing service on this equipment.
