Engine Options:
The manual covers configurations using Oliver's own diesel engines and potentially Perkins diesel engines common in these models. Specific engine displacements vary by model but are typically in the range of 310 to 425 cubic inches (5.1L to 7.0L).
Horsepower Range:
Engine horsepower varied by model, with the 1755 generally around 70-80 PTO HP, the 1855 around 80-90 PTO HP, and the 1955 around 90-100 PTO HP.
Torque Specifications:
Torque figures are detailed within the manual for specific engine models and RPM ranges.
Injection System:
Bosch or CAV injection pumps, with details on timing, calibration, and repair procedures.
Cylinder Configuration:
Inline Diesel (typically 6-cylinder for 1855 and 1955, potentially 4-cylinder for some 1755 configurations or specific engine options).
Cooling Method:
Water-cooled, thermosiphon and fan assisted.
Engine Oil Change:
Typically recommended every 100-250 operating hours, depending on operating conditions. Manual will provide specific intervals and oil types.
Transmission Hydraulic Fluid Change:
Generally recommended every 500-1000 operating hours. Manual specifies fluid type and capacity.
Air Filter Cleaning Replacement:
Regular cleaning or replacement of the air filter element based on operating conditions, typically detailed in hourly intervals or visual inspection.
Fuel Filter Replacement:
Recommended replacement intervals for primary and secondary fuel filters, usually between 250-500 operating hours.
Engine Oil Specification:
Refer to manual for specific API service classifications (e.g., API CD or higher for diesel) and SAE viscosity grades (e.g., SAE 30 or 15W-40).
Hydraulic Transmission Fluid Specification:
Manual will specify the required hydraulic fluid type (e.g., John Deere Hy-Gard equivalent, or specific Oliver branded fluid).
Common Wear Points:
Potential wear in clutch components, hydraulic pump and valve operation, PTO engagement mechanisms, and front axle kingpins. The manual provides diagnostic steps for these.
Electrical System Notes:
While generally robust, older wiring harnesses can degrade. Manual includes wiring diagrams for troubleshooting.
