This is the factory illustrated parts catalog for the Ford 6610 four cylinder agricultural tractor, 10 Series, built January 1981 through December 1993. It is a parts book, not a repair manual: 294 numbered figures across 940 pages, each with numbered callouts tied to Ford part numbers. A Figure Search index up front gets you to the right drawing fast, and figures are numbered by section (01A01 Front Wheel Assembly, 05F07 Manifold and Couplers, 11A01 LH Electrical System). Caption notes list applicability by date range and sibling model (5610, 6410, 6710, 7610, 7710), so you can confirm a part fits your build before you order. Coverage runs from the front axle to the cab, both injection pumps, both transmissions, and Dual Power.

Ford 6610 Common Problems This Manual Covers
Hydraulic lift is slow, weak, or drops under load
Identify wear parts before you split anything open. The Hydraulic Lift and Three-Point Linkage section illustrates the lift cylinder, lift cover, linkage, and draft control piece by piece, and the Engine-Mounted Hydraulic Pump section covers the pump assembly, drive, and tubing, so you can order seals, piston, and pump internals by part number in one pass.
Manual Section: Hydraulic Lift and Three-Point Linkage p. 187Hard starting or fuel starvation under load
Chase the fuel path with the exploded views: tank and sender, filters and lift pump, then the injection pump figures. The catalog shows both the inline and rotary pump installations with every fitting, line, and gasket numbered, so whether you are replacing filters or sending a pump out for rebuild, the part numbers and line routing are all on the page.
Manual Section: Fuel System p. 430Brakes pulling, dragging, or a handbrake that will not hold
The Brakes section breaks out the brake assemblies, linkage and pedals, and both handbrake setups, the transmission handbrake and the twin cable type, plus hydraulic trailer brakes where fitted. The drawings make it easy to spot which clevises, cables, discs, and return springs your tractor uses before you pull the trumpet housings.
Manual Section: Brakes p. 41Whining or knocking from the rear end, or a differential lock that will not engage
Bearing and gear noise from the back of the tractor means parts shopping in the Rear Axle and Differential section: centre housing, differential lock, axle shafts and bearings, and final drives are all drawn with callouts. You can list every bearing, shim, and seal for the job before teardown, which matters when parts take a week to arrive.
Manual Section: Rear Axle and Differential p. 173Frequently Asked Questions
Is this a repair manual with torque specs and step by step procedures?
No. This is the illustrated parts catalog: exploded drawings, part numbers, and applicability notes. There are no torque values, no wiring schematics, and no troubleshooting trees. Use it to identify and order the correct parts, then pair it with a shop manual for procedures. For teardown work the exploded views are still gold, because they show assembly order, washer and seal positions, and every small part you are likely to lose. p. 3
My 6610 cranks but gets no fuel. Will this book help me?
It will help you order the right parts once you have found the restriction. The Fuel System section has separate figures for the inline and rotary injection pumps, plus the fuel tank and sender, filters, lift pump, and injector lines, all with part numbers. On these tractors no fuel almost always comes down to plugged filters, a tired lift pump, or debris in the tank pickup, and every one of those parts is illustrated here so you know exactly what to ask the dealer for. p. 430
Does it cover Ford 6610 fault codes or electronic resets?
There are no fault codes to cover. The 6610 is a fully mechanical tractor with no ECU, no diagnostic menu, and no reset procedures. If a warning lamp stays on, it is a sender, switch, or wiring problem, and the Electrical System and Instruments sections show every sender, lamp, switch, and harness connection point as exploded parts drawings with part numbers. Note these are parts illustrations, not wiring schematics. p. 524
My tractor has Dual Power and a cab. Are those variants in here?
Yes. The Transmission section covers the eight speed non synchronised box, the synchronised gears, Dual Power, shift rails and forks, and the PTO drive. The Cab section runs from the body shell through doors and glass, interior trim, roof and headliner, cab electrical, and the heater and air conditioning. Figure captions carry date ranges, so you can match parts to your serial year within the 1981 to 1993 window. p. 318
Ford part numbers from the 1980s are superseded. Is the catalog still useful?
Very. The original number is your starting point: dealers and aftermarket suppliers cross reference from it to the current supersession or the New Holland equivalent. Just as important, the exploded views tell you how many of each bolt, bushing, seal, and snap ring live in an assembly, so you order the complete job in one go instead of finding out mid rebuild that a thrust washer exists. p. 3
