Oliver 1550 / 1555 / 2-62 Tractor Parts Catalog, 1960s–1970s

This factory illustrated parts catalog covers the Oliver 1550 / 1555 / 2-62 tractor family, with Oliver and Cockshutt emblem and decal applications. Catalog identifier 433 086, issued April 14, 1969, includes sheets issued or revised October 1, 1969. Its tables distinguish row crop (RC), industrial (IND), wheatland (WHT), and utility (UTY) configurations.

Reading and Navigating the PDF

Text search and navigation: PDF text search is not available, and there are no embedded PDF bookmarks. Some small parts-table lettering is faint and benefits from enlargement; crowded illustration callouts also require zooming.

One printable PDF contains 347 pages, including the three-page alphabetical index, one Notes page, 319 assembly and parts-list pages, and the 24-page numerical index. Original unused sheet backs are included in that total.

Engine, Hydra-Power and Tractor Parts Coverage

The following selected catalog contents outline the main assembly groups rather than reproduce the full index. Additional listings include the coolant heater and tool box and tools.

• Engine assemblies: Cylinder head and valves, rocker arms and push rods, crankcase, crankshaft, camshaft, oil pump and filter, manifolds, and cooling components.

• Transmission and brakes: Exploded parts listings for the transmission, gear-shift linkage, clutch, brake controls, brakes, differential, and belt pulley.

• Drive and PTO options: Hydra-Power Drive, Creeper Drive, Reverse-O-Torc industrial drive, and single- and dual-speed power take-off assemblies.

• Hydraulic systems: Hydra-Lectric-Stop and Depth-Stop parts, internal and external valves, hydraulic pumps, flow dividers, servo valves, power-lift cylinders, couplings, hoses, and oil coolers.

• Steering and axles: Manual and power steering, single- and dual-front-wheel layouts, adjustable and short-wheelbase front axles, wheatland/industrial layouts, and extra-high-clearance axle components.

• Body and equipment: Wheels and weights, drawbars, three-point hitch, hood and grille panels, seats, roll bar, cabs and heaters, Weather Break, and Converta Cab equipment.

• Electrical components: Parts breakdowns for ignition, starting and charging equipment, wiring harnesses and clips, lights, instruments, and switches.

This catalog is suited to parts-counter staff, restoration shops, and experienced owners who can read serial-specific parts tables; repair methods must come from the matching service literature.

Fuel-System and Engine Build Differences

Gas pages separate the main tank, one- and two-wheel-guard tank arrangements, narrow-row-cab auxiliary tanks, carburetor, and governor controls. LP-gas coverage adds the filter, regulator, carburetor, and dedicated governor hardware.

Diesel listings identify primary and final fuel filters, the injection pump, injectors and accessory drive, manifold preheater, and the corresponding tank, line, and fitting arrangements. Oil-bath and dry-type air-cleaner plates distinguish the relevant fuel systems and tractor configurations.

The engine tables also separate piston-ring packages for chrome and non-chrome cylinder sleeves. Confusing these applications risks damage to the ring-and-sleeve surfaces.

Hydraulic Layouts and Parts Matching

A factory key separates four internal-valve builds: remote-only or draft-control-and-remote, each in Hydra-Lectric-Stop or Depth-Stop form. Separate coverage identifies the utility layout and the industrial external-valve system.

Those distinctions matter when selecting valves, linkage, cylinders, hoses, and power-lift couplings that may look similar off the tractor. Each parts table connects numbered illustration callouts with factory part numbers, descriptions, quantities, and applicable configurations or serial ranges.

Tractor and Hydra-Power Serial Numbers

Hydra-Power Drive internals follow the drive unit’s own serial number, beginning at 16234. Parts attached to the unit may instead follow the tractor serial number. Ordering Hydra-Power repair parts from the tractor number alone can therefore lead to a mismatched internal component.

Other production changes appear within individual assembly listings. Emblem and decal applications, for example, separate tractors through serial 219 999 from those beginning at 220 000. Alternate parts, replacement assemblies, and package breakdowns remain tied to the affected build.

Exploded Views and Catalog Limits

Representative plates include Cylinder Head and Valves, Hydra-Power Drive, Reverse-O-Torc Drive, Hydra-Lectric-Stop and Depth-Stop Internal Valve System, Power Steering Hydramotor, and Dual-Speed Power Take-Off. The alphabetical index locates assemblies by name; the numerical index connects factory part numbers with catalog pages.

This is an illustrated parts catalog, not a step-by-step repair manual. Overhaul-package listings identify parts rather than explain an overhaul procedure. The catalog does not provide removal sequences, troubleshooting tests, torque tables, valve-clearance data, pressure specifications, fluid capacities, or wiring diagrams.

Use the appropriate service manual for repair procedures and specifications, and securely support heavy frame, axle, and hydraulic assemblies before disassembly.

Selected Seal-Bore and PTO Shaft Identification Details

The crankshaft listings distinguish seals and related pulleys for 2 13/16-inch and 2 3/4-inch cover bores. These are component-identification dimensions, not wear limits or adjustment specifications.

Single-speed PTO listings distinguish a 6-tooth splined shaft for the 540 RPM arrangement from 21-tooth splined shafts for 1000 RPM arrangements. The associated retainers, bearings, and gearing are listed by application.
