Depth:
Comprehensive, covering everything from basic preventative maintenance to complete engine and transmission rebuilds. Suitable for professional technicians and experienced DIY users.
Engine Type:
Typically powered by Ford/New Holland diesel engines. Specific engine displacements and models vary by exact configuration and year (e.g., 3-cylinder naturally aspirated diesel).
Horsepower Range:
Varies by specific engine and model configuration, but generally in the 50-70 HP range.
Torque Range:
Specific torque figures depend on the engine model; the manual will provide precise data.
Injection Type:
Typically direct injection, often with rotary or inline fuel pumps.
Transmission Type:
Often featured a manual transmission (e.g., 8-speed, 16-speed synchromesh) as standard, with options for powershift or shuttle-shift transmissions.
Powershift Option:
Some models may have offered a powershift transmission for easier gear changes under load.
Clutch Type:
Dry single or dual-stage clutch depending on transmission and PTO configuration.
Engine Oil Change:
Typically every 250 hours or annually, but the manual will provide specific recommendations based on operating conditions.
Hydraulic Fluid Change:
Often recommended every 500-1000 hours. The manual will detail exact intervals and filter replacement.
Engine Oil Type:
Ford/New Holland recommended diesel engine oil, e.g., API CG-4 or higher, viscosity grade 15W-40 is common. The manual will specify the exact grade and API classification.
Hydraulic Fluid Type:
Ford/New Holland approved hydraulic fluid, often a universal tractor transmission oil (UTTO) or specific hydraulic oil. The manual will specify the exact type and ISO viscosity grade.
Transmission Fluid Type:
Depends on transmission type; typically specific transmission oil or UTTO. Manual will confirm.
Coolant Type:
Ethylene glycol based antifreeze/coolant mixture (e.g., 50/50). The manual will specify concentration and type.
Common Wear Points:
Wear on bucket pins and bushings, loader control valve leaks, and potential hydraulic hose failures are common in older units. The manual provides repair procedures for these.
Engine Related:
Glow plug issues, fuel filter plugging, and injector wear can occur with age. The manual aids in diagnosing and repairing these.
Ford Tractor Division:
Ford's legacy in agricultural and industrial machinery is extensive, with the Fordson tractor lineage dating back to the early 20th century. The 550/555 series falls under this robust history.
Series Development:
These models represent Ford's continuous development in the compact tractor loader backhoe market, building upon earlier designs for increased power, efficiency, and operator comfort.
Production Era:
Likely produced in the late 1980s and 1990s, following the acquisition of Ford's tractor division by Fiat and the subsequent formation of New Holland.
