1961 Ford 600, 601, 700, 701, 800, 801, 900, 901 & 1801 Tractor Shop Manual (P/N SE 8175)

The 1961 Ford Tractor Shop Manual (P/N SE 8175), prepared by Ford Motor Company’s Tractor and Implement Division, covers Series 600, 601, 700, 701, 800, 801, 900, 901, and 1801 tractors with gasoline, LP-Gas, or diesel engines.

PDF Bookmarks and Wiring-Diagram Detail

Search, navigation, and diagram detail: PDF text search is not available. Embedded bookmarks provide access to the main parts, chapters, and individual service sections. Small component labels and wire-color markings in the checked electrical diagrams are readable when enlarged.

One printable English PDF contains 431 pages total: 420 numbered service pages, 7 front-matter pages, 2 additional pages, and 2 closing cover images, all included in that total.

Engine, Drivetrain, Steering, and Hydraulic Repairs

These selected repair topics outline the manual’s coverage rather than reproduce its complete contents. Further subjects include belt-pulley overhaul and tire-ballasting guidance.

• Engine repair: Step-by-step engine removal, cylinder-head and valve service, oil-pump overhaul, bearing inspection, and crankshaft, governor, and timing-gear work.

• Fuel systems: Gasoline carburetor repair, diesel injector testing and cleaning, injection-pump timing, and LP-Gas carburetor, vaporizer, regulator, and fuel-valve service.

• Clutches and transmissions: Single- and double-clutch repair, four- and five-speed transmission overhaul, Sherman auxiliary transmissions, and Select-O-Speed adjustments and internal service.

• Rear axle and PTO: Differential and pinion overhaul, axle-shaft and center-housing work, PTO assembly repair, and PTO conversion assembly service.

• Steering and brakes: Power-steering pump and cylinder overhaul, Row Crop pedestal repair, front-axle servicing, brake adjustment, and brake-camshaft replacement.

• Hydraulic lift: Lift-cover and lift-cylinder overhaul, control-valve service, draft and position-control adjustment, pump repair, and hydraulic troubleshooting.

• Electrical diagnosis: Gasoline and diesel wiring diagrams, charging and starting-circuit tests, starter-motor overhaul, ignition-switch checks, and distributor service.

Ford’s foreword addresses both inexperienced and experienced mechanics; diesel injector testing requires the specified test equipment and service tools.

Power Plant Service and Diesel Pump Scope

The engine chapter covers dismantling and inspecting main bearings, pistons, connecting rods, crankshaft components, and the valve train. The Valve Initial Adjustment Chart and separate gasoline and diesel Cylinder Head Tightening Sequence illustrations support reassembly.

Engine lubrication diagrams explain oil flow through the bearings and valve mechanism. A dedicated cooling-system chapter covers radiator care, water-pump repair, thermostat testing, and cooling-system troubleshooting.

Diesel injection: Injector coverage extends to opening-pressure, spray-pattern, seat-leakage, and leak-back tests, followed by disassembly, cleaning, inspection, and reassembly. Injection-pump service is limited to complete-unit replacement, drive-shaft and seal work, drive-gear service, pump-to-engine timing, and throttle adjustments; it does not provide a full internal pump overhaul procedure.

Clamping the injector body directly in a vise can distort it, causing leakage or a sticking needle.

Transmission Diagnosis and Configuration Differences

The four- and five-speed sections distinguish single- and double-clutch arrangements. Sherman coverage includes both step-up/step-down and forward/reverse transmissions, with disassembly, inspection, bearing work, shimming, and installation procedures.

Select-O-Speed: The overhaul instructions use Model 81 as their basis, with specific notes for Model 71 and directions for applying the procedures to Model 11. Band adjustments, selector synchronization, control-valve alignment, servo pressure checks, and diagnosis tables help connect a transmission symptom with the affected hydraulic or mechanical circuit.

Incorrect PTO control-cable adjustment can cause loss of transmission lubrication and PTO-clutch slippage.

The rear-axle chapter identifies production changes in driveline splines and axle-shaft/side-gear combinations. These distinctions help select compatible replacement parts before committing to an axle repair.

Steering, Hydraulic Lift, and Chassis Service

Separate power-steering sections address General Purpose, Row Crop, and Industrial tractors. Front-axle coverage includes standard and heavy-duty arrangements, early and late Row Crop pedestals, spindle service, and wheel-bearing replacement.

Hydraulic procedures distinguish vane pumps from piston pumps, including ball- and roller-bearing piston-pump constructions. Lift-cover work includes control-linkage adjustment using the NCA-503-B lift-arm positioning gauge and the associated adjustment gauge.

Maintenance and lubrication charts supplement the repair chapters with service schedules and lubrication points for the different tractor configurations.

Review the factory safety precautions before lifting heavy engine components or opening pressurized fluid systems.

Electrical Troubleshooting and Ignition Inspection

The wiring coverage distinguishes the gasoline and LP-Gas six-volt positive-ground system from the diesel twelve-volt negative-ground system, including the diesel manifold-heater circuit.

The Distributor—Disassembled view supports component identification during overhaul. The Manifold Vacuum Gauge Readings table and Engine Does Not Develop Full Power troubleshooting road map help relate engine symptoms to further checks.

A Preview of Valve-Clearance and Vacuum References

For valve adjustment, the manual specifies 0.014–0.016 inch clearance for both intake and exhaust tappets with the engine at normal operating temperature and running at idle.

For gasoline and LP-Gas engine diagnosis, the manifold-vacuum reference is 18 in. Hg at sea level with the engine running at 450 rpm under no load. The accompanying diagnostic section explains how abnormal readings can relate to valve, compression, or intake-leakage problems.
