1960–1970 Oliver 550 / Cockshutt / White Tractor Parts Catalog (P/N 433 106)

• Identifies 550 and 2-44 tractor parts across Oliver, Cockshutt, and White decal/nameplate applications, including agricultural, industrial, loader, and loader/backhoe configurations.
• Separates gasoline and diesel equipment, regular and shuttle-reverser transmissions, manual and power steering, fixed and adjustable front axles, and tractors with or without hydraulic equipment.
• Breaks down the cylinder head, crankcase, crankshaft and piston assemblies, camshaft, lubrication system, water pump, radiator, gas carburetion, and diesel fuel-injection equipment.
• Maps the gear shift, clutch, brakes, differential, rear axle, belt pulley, power take-off, and Power Take-Off Speed Conversion Unit with reference-numbered parts plates.
• Details the Double Feed-Back Hydraulic Control, lift-cylinder and valve assemblies, cylinder hoses and connections, three-point hitch, swinging drawbar, and related control linkages.
• Includes ignition and starter parts, ignition wires and clips, lights, instrument panel, switches, tachometer, hood and grille, seats, wheels, rims, weights, platform, and tool box.
• Uses illustrated reference numbers tied to tables for part number, description, quantity, Gas/Dsl applicability, alternates, package assemblies, and serial breaks; alphabetical and numerical indexes support lookup from either an assembly name or a known part number.
• 192 PDF pages; Form No. 433 106; issued May 22, 1970.

Parts Documentation Overview

Finding the right hardware for a 550 or 2-44 rebuild is often less about recognizing the assembly than identifying the exact production version. This catalog is arranged for that job. Each illustrated plate assigns reference numbers to individual components, while the corresponding list supplies the listed part number, description, quantity required, fuel-type applicability, and serial-number information. Alternates, kits, and package breakdowns are carried in the descriptions where the publication provides them.

Engine coverage runs from the cylinder-head cover, rocker arms, push rods, valves, crankcase, crankshaft, pistons, connecting rods, and camshaft through the oil pan, oil pump, filter, water pump, fan, radiator, and coolant-heater equipment. Gasoline pages separate the carburetor, manifold, air cleaner, muffler, fuel tank, governor controls, and foot accelerator. Diesel coverage adds the intake manifold, air cleaner, muffler, manifold preheater, ether-primer starting system, primary and final fuel filtration, injection pump, injectors, accessory drive, and diesel governor linkage.

The powertrain plates distinguish the regular transmission from the shuttle reverser rather than treating them as one interchangeable assembly. Separate breakdowns cover the gear shift, clutch, rear main frame, brakes and brake controls, differential, rear axle, PTO, PTO clutch components, speed-conversion unit, and belt pulley. Chassis and operator-equipment sections extend to front and rear wheels, rims and weights, front-frame weights, wheel guards, platform and tool box, seat assemblies, hood and grille, steering systems, drawbar, and three-point hitch.

Variant and Serial-Number Control

The listings begin with applications marked 60 501 and up and use serial breaks line by line instead of assuming one part fits every tractor. Important transitions appear at ranges such as 110 015/110 016, 149 064/149 065, and 176 054/176 055, with additional breaks inside individual assemblies. That structure is especially useful when two castings, brackets, shafts, or linkages look similar but changed during production.

The emblem, decal-set, and nameplate pages distinguish Oliver, Cockshutt, and White identities, along with agricultural, industrial, loader, and loader/backhoe applications. Other listings separate manual from power steering, fixed from adjustable front axles, regular from shuttle-reverser transmission hardware, and tractors with or without hydraulic equipment. Before ordering for a repair, match the tractor serial number, fuel type, transmission, steering, axle, and equipment configuration to the plate code and serial column.

Illustrated Assembly Coverage

Representative plates include Cylinder Head, Injection Pump, Injectors and Accessory Drive - Diesel, Transmission - Shuttle Reverser, Double Feed-Back Hydraulic Control, Power Steering, and Three Point Hitch. These views show the relative location and relationship of gears, shafts, bearings, retainers, seals, valves, rods, brackets, and attaching hardware without reducing the catalog to a generic component list.

Regular-transmission and shuttle-reverser parts should not be cross-selected; the hydraulic-control housing is also cataloged differently for those transmission configurations. Gas and diesel fuel equipment has separate tanks, lines, filters, manifolds, controls, and starting aids, so appearance alone is not a safe basis for ordering. Early and late accelerator, steering, seat, and wheel-related parts can also differ by serial break; using the wrong version can leave a repair with components that do not fit or operate through the intended linkage travel.

Catalog Scope for Repair Work

This publication is an illustrated parts catalog, not a service manual. It is intended for component identification and parts ordering; it does not provide teardown sequences, inspection limits, torque tables, valve-clearance procedures, hydraulic pressure tests, fluid capacities, electrical test values, troubleshooting charts, or diesel injection adjustment instructions. Use the applicable shop manual for those operations.

Before hydraulic, steering, brake, clutch, PTO, axle, or wheel-weight repair, relieve stored pressure, block and support the tractor and heavy components, and follow standard workshop safety practices.
