1981–1993 Ford 6610 10 Series Tractor Parts Manual (P/N TP-193)

This parts catalog covers the 1981–1993 Ford 6610 4-cylinder AG tractor, 10 Series, in 2WD and FWD configurations. Shared figures also include selected 5610, 6410, 7610, and 7710 applications; the individual parts listings identify the applicable model and equipment.

• Engine and fuel: Exploded parts listings for cylinder blocks, valve gear, DPA and DPS rotary injection pumps, inline pumps, and application-specific turbocharger assemblies.

• Transmission and PTO: Non-synchronized and synchronized transmissions, Dual Power assemblies, reduction gear boxes, PTO clutches, shift controls, and matched replacement components.

• Axles and steering: Front and rear axle breakdowns, limited slip differentials, power steering pumps, cylinders and mounts, and steering gear columns.

• Lift hydraulics: Lift covers, cylinders, load monitors, linkages, engine-mounted hydraulic pumps, and remote control valves with single- and double-spool parts listings.

• Brakes and wheels: Brake controls, transmission handbrakes, hydraulic trailer brakes, front and rear wheel assemblies, adjustment hardware, and ballast components.

• Cab and electrical: Cab harnesses, field performance monitors, Bostrom suspension seats, ROPS safety frames, heater and air conditioning evaporators, and compressor parts.

Suited to mechanics and experienced owners who can identify installed assemblies and use figure callouts and application notes to select repair parts.

Parts Identification and Repair Scope

The catalog pairs exploded views with part numbers, quantities, production-date notes, and replacement information. Entries such as Dual Power Assembly (07A05) and Limited Slip Differential (03L04) connect numbered components to their parts lists.

Repair scope: This is a parts catalog, not a procedural workshop manual. The drawings show component relationships but do not supply step-by-step overhaul sequences, injection-pump calibration, or transmission adjustment procedures.

Always verify local shop safety protocols and use appropriate lifting equipment before handling heavy tractor chassis components.

Axle Changes and Matched Replacement Parts

Steering configuration: The APL-325 steering-cylinder listings flag an end-cap arrangement that may have been updated to APL-335 style. Checking those cap, seal, and retainer entries helps you select parts for the assembly actually installed on the tractor.

Transmission compatibility: PTO drive-plate entries identify matching shaft requirements. Synchronized transmission listings also identify gear, bearing, and coupling groups that must be replaced together, helping you check the complete replacement group before ordering individual components.

Production-date notes, including the October 1985 changes, distinguish early and late applications. The hardware appendix also excludes mixing metric and inch threads in nuts, bolts, and tapped holes—a relevant precaution against thread damage when replacing catalog hardware.

Fuel, Cooling and Hydraulic Assemblies

Injection systems: Separate figures distinguish DPA rotary, inline, and DPS fuel injection equipment. The DPS upper- and lower-half drawings (09C03 and 09C04) identify internal pump components; the turbocharger section includes the specific 6610 Switzerland application.

Cooling-system listings cover radiators, water pumps, water-pump repair kits, and oil coolers, with application notes alongside the component entries.

Hydraulic lift: Hydraulic Lift Cylinder figures 05B01 and 05B03 distinguish earlier assemblies from the replacement design. Cross-references and the FP543 valve-conversion kit entry help identify the associated components when an assembly or valve has already been changed.

Electrical Parts Illustrations and Cab Equipment

Cab Electrical System (15A07) and the rear-wiring figures show harness assemblies, mounting hardware, and component locations. These are parts illustrations, not electrical circuit schematics or troubleshooting charts.

Cab listings distinguish LP-cab and Q-cab equipment. Bostrom seat and suspension entries separate the serial-number formats, while heating and air conditioning sections identify hoses, evaporators, dehydrators, and compressor components.

Examples of Hydraulic Lift Parts Dimensions

These entries are a small selection of the dimensional information provided for parts identification.

In Hydraulic Lift Cylinder figure 05B03, the white select-fit bushing E0NN481JA is listed at 1.0002–1.0004 inches. Lift piston D5NN530A is identified by its 4.12-inch diameter. These are catalog dimensions for the listed components, not wear limits or workshop adjustment specifications.

PDF Search, Navigation and Page Breakdown

Text search and illustration detail: Figure headings, the index, and parts lists are searchable; callouts within drawings are not covered by text search. Bookmarks open the search guide, index, catalog start, abbreviations, and hardware conversions. Small callouts in dense electrical parts illustrations require zooming. Some entries lack an illustration, including LP-cab electrical equipment and air conditioning conversion kits.

The download is one printable, 957-page PDF, including 931 catalog pages, seven index pages, 14 abbreviation pages, and two hardware-conversion pages. The total also includes a one-page search guide, one introductory supplementary page, and one blank page.
