1978–1985 Ford 545 Tractor Loader Parts Manual

This parts manual covers the 1978–1985 Ford 545 tractor loader, with shared-component references for the 340, 445 and 540 series and the 545A. Numbered exploded views connect individual components to part numbers, quantities and application notes.

Searchable Parts Lists and Printable PDF

Parts lookup and illustration detail: Text search works in the figure index, parts tables and figure headings; illustration callouts are not searchable. Six embedded bookmarks open the main file sections. Smaller callouts in the electrical parts views benefit from zooming.

Supplied as one printable, 497-page PDF, including 474 pages of illustrated parts listings and a four-page figure index. The total also includes one figure-search guide, one supplementary cover, 14 abbreviation pages, two hardware-conversion pages and one blank page.

Engine, Drivetrain and Attachment Parts

These selected topics show the main component coverage; the catalog also lists diesel cold-start equipment and engine coolant heater kits.

• Engine and fuel systems: Gasoline and diesel parts listings, injection-pump internals, Holley and Zenith carburetors, cooling components and engine gasket kits.

• Transmission and PTO: Exploded assemblies for manual reversing, torque-converter power reverse and eight-speed transmissions, with transmission PTO and Independent Power Take-Off components.

• Steering and hydraulics: TRW and Cessna steering-cylinder parts, power-steering pumps, hydraulic lift assemblies, flow control valves and remote control valves.

• Axles, wheels and brakes: FWD axle and transfer-case parts, rear differentials, differential lock linkage, wheel assemblies, disc brakes and handbrake hardware.

• Loader and backhoe: Lift and bucket cylinders, center-pivot frames, boom and dipstick assemblies, stabilizer pads and alternative backhoe control arrangements.

• Electrical and operator equipment: Harness and lighting layouts, starting motors, alternators, instrument clusters, fenders, seats and rollover protection system components.

This catalog suits mechanics and owners who can identify installed assemblies and interpret parts diagrams when selecting components for a repair.

Engine, Fuel and Cooling Components

Separate gasoline and diesel listings cover cylinder heads, blocks, pistons and connecting rods. Crankshaft, valve-train and lubrication illustrations extend the engine coverage, alongside radiator and water-pump assemblies.

Figure 09C01, Fuel Injection Pump, identifies internal pump components. Separate Holley and Zenith carburetor lists distinguish their replacement parts, while diesel fuel-system pages cover single-filter, dual-filter and sedimenter arrangements.

Transmission, PTO and Rear Axle Parts

Figure 07A02, Manual Reversing Transmission Gears & Related Parts, shows shafts, gears and PTO-dependent component differences. Torque-converter sections distinguish non-synchromesh and synchromesh power reverse assemblies by application date, with separate clutch, oil-pump, filter and cooler-tube listings.

PTO replacement requirements: Figure 07D01 links a replacement shaft to companion bearing and cover changes. Those notes help identify the related components required before ordering the shaft alone.

Rear-axle illustrations separate differential lock components, linkage and center-housing parts. Gear-set listings also identify casting-number differences between standard and handbrake applications.

Steering Cylinders and Hydraulic Pumps

Figure 03D01, Steering Cylinder Assembly, TRW & Cessna, separates the cylinder components. Power-steering pump and valve applications are listed independently from the engine-mounted and center-housing hydraulic pumps.

The hydraulic sections distinguish piston-type and gear-type pumps, hydraulic-lift configurations and PTO-dependent flow-control components. Repair-kit listings identify included parts and additional requirements; they do not provide pump-testing or overhaul procedures.

Loader and Center-Pivot Backhoe Components

Loader illustrations cover return-to-dig controls, hydraulic lines, relief valves and pump-drive parts. Backhoe listings extend through the frame, swing post, control conversions and hydraulic cylinders.

Figure 20G01 covers Boom & Dipstick Assemblies & Related Parts. Figure 20H04, Stabilizer Cylinder Assembly, Center Pivot, distinguishes piston and packing designs. Its nylon piston rings are not replaceable separately; attempting to remove them can damage the piston’s sealing components.

Electrical Parts, Wheels and Repair Limits

Electrical illustrations show harness arrangements and component locations, including backhoe fender wiring with and without ROPS. These are parts illustrations, not troubleshooting circuit schematics.

Wheel listings distinguish rim and disc configurations. Brake sections identify four-plate components and twin-cable handbrake hardware; operator-equipment pages cover safety rails, seat-belt kits and ROPS configurations.

The catalog supports parts identification and selection rather than step-by-step repair, diagnostic testing, tightening procedures or workshop adjustments. Referenced service bulletins are separate documents.

For work on brakes, hydraulic cylinders or raised attachments, use the applicable service manual’s safety procedures and specifications.

Selected Rear-Axle Gear and Stabilizer-Rod Sizes

Rear-axle tables list 3.50:1 gear sets for standard and handbrake applications, with different pinion casting numbers. The ratio alone does not identify the correct replacement set.

Center-pivot stabilizer-cylinder listings distinguish assemblies with 2-inch and 2-1/4-inch rods, with corresponding packing and gland parts. These dimensions identify component versions; they are not cylinder wear limits.
