1958 Massey-Ferguson TO-35 Tractor Parts Catalog (P/N 693 063 M2)

Getting the exact replacement part for a vintage TO-35 requires precise factory data. This Massey-Ferguson parts catalog, Form No. 693 063 M2, Issue 1 (June 1958), is the North American Parts Division reference for gas and diesel models. It provides illustrated parts identification for repair and restoration, not step-by-step workshop procedures.

• Engine components: Illustrated listings for cylinder blocks, timing gear covers, crankshafts, camshafts, flywheels, pistons, connecting rods, cylinder heads, valves, and gasket kits.

• Fuel and governor systems: Carter and Marvel-Schebler carburetor breakdowns, gas-engine governor components, diesel fuel pumps, injection-pump drives, filters, injectors, and fuel lines.

• Cooling and lubrication: Radiator, thermostat, and water-pump assemblies, plus oil pumps, oil pans, filters, pressure gauges, and associated hardware.

• Powertrain and chassis: Single- and dual-clutch parts, transmission and gearshift listings, differentials, front and rear axles, brakes, power take-off, wheels, and belt-pulley drives.

• Hydraulics and steering: Hydraulic lift cover, shaft, pump, and linkage parts; manual and power steering; single and dual control valves; remote hydraulic cylinders.

• Electrical wiring: Pictorial wiring diagrams and component references for ignition, charging, starting, instruments, and lighting, with separate distributor, generator, starter, and solenoid breakdowns.

• Body and attachments: Hood panels, decals, seats, platforms, fenders, drawbars, lift rods, and stabilizers, with illustrated references and attaching-part listings.

This catalog is suited to restorers and mechanics who can identify assemblies from illustrated parts lists and interpret serial-number footnotes.

Serial Numbers and Parts Identification

Pictorial and group indexes locate assemblies, while the numerical index points known part numbers to their listings. The identification guide shows tractor and engine serial-number locations and explains the fuel and clutch prefixes, including regular-altitude and Hi-Alt gas configurations.

Gas short-block listings distinguish tractors before and from serial 162606. A separate Carter carburetor listing applies from 175639 onward. These notes help match replacement assemblies to the tractor before parts are ordered.

Engine Parts and Diesel Injection Coverage

The gas-engine gasket section identifies Part No. 830 689 M91 and lists the individual contents of the engine gasket kit. Water-pump breakdowns identify housings, shafts, seals, and repair-kit options. Diesel piston and liner listings distinguish letter grades, with connecting rods separated into weight groups.

The diesel injection section covers the pump assembly, drive housing and gears, injectors, filters, and lines. Internal injection-pump parts are excluded from its service-parts listing; the catalog refers their servicing to certified C.A.V. service stations.

Clutch and Hydraulic Fitment Notes

Dual-clutch assembly 184 541 M91 is listed for tractor serials 177395–177519 and 177538 onward. The earlier assembly applies before 177395 and also to 177520–177537, making the transitional serial notes important when identifying clutch and flywheel parts.

Single-clutch listings distinguish agricultural and industrial types. A split-torque replacement for the dual clutch is also cataloged, with specific release-bearing/carrier combinations flagged for careful checking before ordering.

Hydraulic pump, lift shaft, piston, and cylinder changes are identified at serial 179304. The auxiliary control-valve listings distinguish early and late equipment and their associated spool components.

Check complete tractor and engine serial numbers when ordering replacements, and follow appropriate heavy-equipment safety precautions during any teardown.

Examples of Bearing Sizes and Differential Gearing

These examples represent a small selection of the sizing and fitment details in the parts listings.

Gas-engine main-bearing insert kits include a 0.010-inch undersize version, with separate references for the front, center, and rear inserts. This is a replacement-part size, not a bearing-clearance specification.

Before tractor serial 169467, the differential matched set uses a 40-tooth ring gear; from 169467 onward, the listed set uses a 37-tooth ring gear. Both listed sets use a 6-tooth bevel pinion.

PDF Search, Navigation, and Page Coverage

Search and illustration access: Embedded OCR supports text searches, but recognition errors affect some part numbers and labels. There are no PDF bookmarks, and small wiring labels require zooming. Printed pages 90 and 120 are missing, while two parts-list pages are repeated. The remote-cylinder and control-valve drawings do not immediately face their matching lists.

A single 154-page printable PDF in English: 18 front-matter pages, 135 main-section pages, and one blank end page. The total already includes the cover, instructions and indexes, one original promotional page, one blank front-matter page, and the two repeated parts-list pages.
