2003-onwards New Holland TC55DA EHSS Compact Tractor Parts Catalog

• TC55DA coverage: Covers the New Holland TC55DA EHSS compact tractor identified as “7/03-”, with a dedicated 150-page tractor section and 65 indexed illustrated-parts figures.
• Engine and powertrain coverage includes the cylinder block, cylinder head, crankshaft and pistons, fuel injection system, turbocharger, clutch case, front-transmission HST, hydraulic clutch, transmission gearing, PTO clutch, and rear PTO drive.
• Chassis and hydraulic figures cover the FWD front axle, steering cylinder and gearbox, power-steering pump and case, front differential and final drives, brakes, differential lock, lift cover, draft-control linkage, and EHSS/PTO pump and piping.
• Electrical content identifies the main, rear, headlight, and EHSS harnesses along with safety switches, control blocks, instrument-panel components, worklights, and starting and charging assemblies.
• Separate illustrated catalogs cover 716B/716C/716D snow blowers; 756B/C through 759C backhoes; 7106, 7109, 7308, 7309, 16LA, and 17LA loaders; 914/914A mowers; 105A tillers; and the 702C front blade.
• Each exploded view is keyed to reference-number, part-number, quantity, and description tables, including repair kits, component-number applications, serial breaks, “not serviced separately” notes, and model-specific mounting hardware. This is a parts-identification catalog set, not a repair procedure manual.

This PDF is suited to repair shops, parts departments, and experienced owners who can identify assemblies from exploded figures and parts tables before a repair begins. It assumes the user already has the appropriate service information for disassembly, adjustment, testing, and safe machine support.

TC55DA Tractor Content

The tractor catalog reaches well beyond exterior service items. Engine figures break down the long block, camshaft, cylinder head, crankshaft and pistons, timing case, balancer, lubrication and cooling pumps, injection pump, injectors, alternator, and starter. Intake, exhaust, turbocharger, fuel-tank, radiator, battery, and air-cleaner assemblies are covered separately.

Powertrain indexing follows the parts from the clutch case through the front transmission and shift mechanism, HST assembly, hydraulic clutch, column shift, change levers, PTO clutch, and upper and lower rear-transmission shafts. The FWD running-gear section then identifies the front axle, steering cylinder, power-steering plumbing, differential gears, and final-reduction assemblies.

Useful figure examples include the Cylinder Block exploded view, Front Transmission HST, Front Differential Gears with FWD, EHSS & PTO Pump and Piping, Gresen V-10 backhoe control-valve breakdowns, and the 716B front mounts for SuperSteer and non-SuperSteer axles.

Hydraulic and rear-equipment content includes the lift-cover assembly, PTO control valve, draft-control quadrant and linkage, three-point hitch, drawbar kits, and the two-spool remote-control valve and piping kit. The final TC55DA section provides an initial stocking list divided into preventive-maintenance parts and components commonly required for basic repair.

Additional Equipment Catalogs

A substantial portion of the file covers equipment other than the TC55DA. The backhoe catalogs identify model-specific subframes, mounting adapters, hydraulic kits, control valves, hoses, swing posts, booms, dippersticks, buckets, stabilizers, and individual cylinder repair kits. Loader sections include mounting packages, hydraulic plumbing, self-leveling valves, lift and bucket cylinders, quick-attach devices, forks, bale spears, buckets, and third-function hose kits.

Snow-blower coverage distinguishes front- and rear-mount assemblies, blower widths, PTO configurations, gearboxes, reduction boxes, drivelines, hydraulic chute rotators, deflector kits, quick hitches, and SuperSteer applications. Mower, tiller, and front-blade catalogs provide similar illustrated breakdowns for decks, blades, spindles, gearboxes, drivelines, lift linkage, tines, hydraulic cylinders, and mounting components.

These additional catalogs carry their own model, component-number, date, and serial-break notes. Their inclusion does not establish compatibility with a TC55DA; fitment must be matched to the equipment and tractor models named in the applicable table.

Parts-Selection Cautions and Scope

The TC55DA cylinder-head table lists two different head-gasket thicknesses. Selecting by model name alone can result in incorrect installed clearance and possible internal contact. Snow-blower driveline parts also change by serial break, PTO speed, shaft configuration, and gearbox version; a mismatched shaft or gearbox can damage the coupling or input assembly.

This catalog does not provide removal sequences, overhaul instructions, torque tables, valve-clearance procedures, hydraulic pressure tests, calibration steps, troubleshooting charts, connector pinouts, or electrical wiring diagrams. Dimensions, hardware grades, and occasional valve ratings appearing in part descriptions are identification data rather than service specifications.

Before repair work involving raised loaders, backhoes, snow blowers, stored hydraulic pressure, or PTO drivelines, use the correct service instructions and properly secure and isolate the machine. Those safety and repair procedures are outside the scope of this illustrated parts catalog.
