Routine checks, fluid level monitoring, filter replacement (if applicable), and lubrication recommendations for the power steering system.
Troubleshooting Guide:
Systematic approach to diagnosing and resolving common power steering issues such as leaks, stiffness, or erratic operation.
Depth:
Comprehensive, covering from basic maintenance and inspection to full component overhaul and system diagnostics, suitable for experienced mechanics and dedicated DIY enthusiasts.
File Format Details:
Digital PDF format, offering searchability and easy navigation. Likely optimized for printing individual sections or the entire document.
Print Quality Potential:
Dependent on the original scan quality, but generally expected to contain clear diagrams and text. Optimized for digital viewing and printing.
Binding Type Original:
Original manuals were likely bound with staples or a sewn/glued spine for a workshop environment.
Paper Type Original:
Original manuals typically used durable, uncoated paper stock to withstand shop conditions.
Engine Options:
The 600-800 series tractors were offered with various Ford gasoline and diesel engines. Common gasoline engines included the 134 cubic inch (2.2 L) overhead valve 'Red Tiger' four-cylinder, and larger displacement engines for the 800 series. Diesel options were also available. This manual does not cover engine overhaul but is essential for the power steering system of these tractor models.
Performance Notes:
Power steering significantly improved the operator's ability to maneuver the tractor, especially under load or at low speeds, reducing fatigue and increasing efficiency.
Fuel System Notes:
While not covered in this power steering supplement, these tractors typically used updraft or downdraft carburetors for gasoline engines and injection systems for diesel variants.
Transmission Type:
Ford's Select-O-Speed transmission was an advanced option, but many 600-800 series tractors were equipped with a conventional 4-speed or 5-speed manual gearbox with a live PTO and a two-stage clutch.
Optional Transmission:
Select-O-Speed (Powershift) transmission.
Transmission Features:
The power steering system operates independently of the transmission, but proper hydraulic system maintenance is crucial for both.
Dimensions Notes:
Specific dimensions vary by exact model (e.g., 641, 651, 661, 841, 851, 861, 871, 881) and tire configurations. Generally, these were medium-frame tractors.
Weight Notes:
Base operating weights ranged from approximately 3,000 to 4,500 lbs (1360 to 2040 kg) depending on engine and configuration.
Safety Ratings:
No standardized safety ratings (like modern NCAP) existed for tractors in 1957. Safety was primarily based on operator training and proper maintenance.
Active Safety Features:
Power steering itself can be considered an active safety feature, reducing operator fatigue and improving control, thus minimizing the risk of accidents.
Passive Safety Features:
Basic rollover protection was not standard. Operator presence and awareness were primary safety considerations.
Power Steering Fluid Check:
Check power steering fluid level at least every 50 operating hours or before extended use. Top off as needed.
Power Steering Filter Replacement:
Replace power steering fluid filter annually or every 250-500 operating hours, depending on operating conditions and fluid cleanliness.
Hydraulic System Flush:
Flush and replace hydraulic fluid and filter every 500-1000 operating hours or every 2-3 years, following manufacturer recommendations for the specific fluid type.
Power Steering Fluid Type:
Ford specified its own hydraulic fluid (e.g., Ford 134D Universal Tractor Fluid or equivalent specification) for the power steering and hydraulic system. Check the manual for precise identification of the required fluid type and viscosity for 1957 models.
Hydraulic System Capacity:
Typical hydraulic system capacity (including power steering and three-point hitch) was around 5-7 gallons (19-26 liters). Consult the manual for exact capacity.
Common Issues:
Wear in the control valve spool and cylinder seals leading to stiff steering, leaks, or loss of assist. Pump seal leaks. Air in the system causing 'chatter' or rough operation. Over time, hoses can degrade and leak.
Preventative Maintenance:
Regular fluid changes with the correct specification fluid and filter replacement are critical to prevent internal wear and contamination, which are the primary causes of power steering system failure.
Brand Heritage:
Ford's agricultural division, established in the early 20th century, revolutionized farming with mass-produced, reliable tractors. By 1957, Ford was a major player in the global tractor market.
Model Evolution:
The 600 and 800 series were part of Ford's extensive 'Hundred' series, representing a significant step in tractor design and capability. Power steering was a key option that enhanced their utility and operator comfort.
Production Period:
The 600/800 series were produced from 1955 through 1957/1958, before being succeeded by the 2000/4000 series tractors.
