Displacement:
Not specified, but typical for tractors of this size from the mid-20th century would range from approximately 2.5 to 3.5 liters, depending on the specific engine variant.
Fuel Type:
Diesel (common for this era of Oliver industrial tractors).
Horsepower:
Not specified, but typically in the 40-60 PTO horsepower range for tractors of this class in the 1950s-1960s.
Torque:
Not specified, but essential data for engine repair and tuning would be present in the manual.
Injection Type:
Likely direct injection or pre-combustion chamber injection, depending on the specific engine model.
Fuel Pump:
Details on mechanical fuel pump operation, testing, and replacement.
Type:
Water-cooled, typically with a radiator, fan, and thermostat.
Type:
Pressurized wet-sump system.
Type:
Likely a multi-speed manual transmission, possibly with a high-low range gearbox or a torque amplifier (TA).

Detailed gear ratios for all forward and reverse gears would be provided for diagnostic and repair purposes.
Clutch:
Specifications for clutch operation, adjustment, and replacement of friction plates and pressure components.
Wheelbase:
Not specified, but typical for a utility tractor of this era, likely in the 70-80 inch range.
Length:
Not specified, but would be detailed in the manual.
Width:
Not specified, but would be detailed in the manual.

Details on mechanical and/or hydraulic braking systems, including parking brake operation and maintenance.
Operator Station:
Information on safe mounting/dismounting, control layout, and emergency stop procedures.
Engine Oil:
Typical intervals would be 50-100 hours, with specific recommendations in the manual based on operating conditions.
Air Filter:
Service intervals depend on dust conditions, usually requiring cleaning or replacement every 50-150 operating hours.
Fuel Filter:
Replacement typically every 250-500 hours or as needed based on fuel quality.
Hydraulic Fluid:
Change intervals typically every 250-500 hours, with filter replacement at the same time.
Engine Oil Viscosity:
Likely SAE 30 or 10W-30 diesel engine oil, depending on ambient temperature. Manual will specify exact API service category.
Hydraulic Transmission Fluid:
Typically a specific tractor hydraulic fluid (e.g., TO-2 specification) or a multi-viscosity engine oil like 10W-30, as Oliver often combined hydraulic and transmission lubrication.
Coolant:
A mix of antifreeze and water, likely a conventional ethylene glycol coolant with appropriate corrosion inhibitors. Capacity and mix ratio specified in manual.
Hydraulic System:
Common issues can include slow or weak hydraulic lift, leaky cylinders or pumps, and worn control valves due to age and wear.
Engine Wear:
Wear in the engine, such as worn piston rings, bearings, or valve guides, leading to increased oil consumption or loss of power.
Transmission Synchronizers:
Wear in transmission gears or synchronizers (if equipped) can lead to difficult shifting or gear grinding.
Electrical System:
Corrosion in wiring harnesses and connections can cause intermittent electrical faults or complete system failures.
Oliver Heritage:
Oliver Corporation was a prominent American manufacturer of farm and industrial machinery, known for robust and reliable tractors. The Super 55 series represented a significant development in their product line during the mid-20th century.
Super 55 Line:
The Super 55, 55HC, and 550 HC models likely represent iterative improvements and variations of a successful tractor platform designed for versatility in agricultural and industrial applications.
