Engine Type Diesel:
Likely a variant of the Waukesha diesel engine (common for Oliver tractors of this era), or similar industrial diesel. Specific displacement and cylinder count not provided, but common configurations include 3-cylinder or 4-cylinder.
Engine Type Hc:
Likely a gasoline or LPG (Liquefied Petroleum Gas) engine, typically a 4-cylinder overhead valve design. Specific displacement and power output vary by exact model year and configuration.
Engine Configuration Common:
Inline 3-cylinder or 4-cylinder diesel/gasoline engines.
Horsepower Range Estimated:
Typically in the 40-55 PTO horsepower range, depending on engine and transmission configuration.
Fuel System Diesel:
Injection pump (e.g., CAV, Stanadyne) with mechanical governor, diesel injection nozzles.
Fuel System Gasoline Lpg:
Carburetor (e.g., Marvel-Schebler, Zenith) for gasoline variants; appropriate vaporizer and regulator for LPG.
Carburetor Identification Example:
For gasoline/LPG models, may cover specific carburetor models like Zenith or Marvel-Schebler used in Oliver tractors of the period.
Engine Oil Change Interval:
Typically every 50-100 operating hours or annually, depending on engine type and operating conditions.
Air Filter Maintenance:
Regular cleaning or replacement of the air filter element based on operating conditions, typically every 50-200 hours.
Coolant Flush Interval:
Coolant flushing and replacement typically recommended every 1-2 years or as specified by coolant type.
Engine Oil Type Diesel:
API CD or CE rated diesel engine oil, SAE 30 or 10W-30 depending on ambient temperature.
Engine Oil Type Gasoline:
API SF or SG rated gasoline engine oil, SAE 30 or 10W-30 depending on ambient temperature.
Hydraulic Fluid Type:
Typically a UTF (Universal Tractor Transmission) fluid or a hydraulic oil meeting specific viscosity and anti-wear properties (e.g., ISO VG 32/46).
Transmission Fluid Type:
Often shares fluid with the hydraulic system (integrated transaxle/hydraulic reservoir), so UTF or compatible hydraulic oil.
Gear Oil Specifications:
Gear oil for the transmission and differential typically SAE 90 or SAE 80W-90 GL-4 or GL-5 rated gear oil, depending on the specific gearbox and manufacturer recommendations.
Known Issues:
Common vintage tractor issues include wear in the transmission and clutch, potential leaks from seals and hoses, carburetor or injection pump tuning for gasoline/diesel engines respectively, and maintenance of the hydraulic system's pump and valves.
Oil Filter Part Number Example:
Cross-reference specific to engine, but common replacements might be from Baldwin (e.g., B72), Wix, or Donaldson (e.g., P550267).
Fuel Filter Part Number Example:
Cross-reference specific to engine, but typically an inline or cartridge type. For diesel, examples might be Baldwin (e.g., PF7700) or WIX.
Brand Heritage:
Oliver Farm Equipment Company was a prominent American manufacturer of agricultural machinery, known for its distinctive green and yellow paint scheme and robust engineering.
Model Evolution:
The Oliver 55 series and its derivatives represent a mid-range tractor offering from Oliver, evolving from earlier models to incorporate improvements in engine power, hydraulics, and operator comfort. The '550' often indicates a later or refined version, while 'HC' variants typically denote High Crop configurations.
Parent Models:
Built upon the foundation of Oliver's successful Row Crop tractors and utility tractors of the era.
Production Period Estimated:
The Oliver 550 series was primarily produced from the mid-1950s into the early 1960s. The specific 'Super 55HC' and '550 HC' models would have been part of this production run, with 'HC' signifying a high-crop variant designed for row-crop cultivation.
