Engine Type:
Likely Fiat-based diesel engine (specific model designation not provided in product info, typical for this series is 8040 series)
Displacement:
Estimated around 4.0 - 5.0 Liters (typical for 100hp class Fiat tractors of that era)
Horsepower:
Approximately 100 HP (as indicated by model number)
Injection Type:
Likely Direct Injection Diesel with mechanical or electronic injection pump (specifics in manual)
Cooling Method:
Liquid-cooled (water/antifreeze mixture)
Oil Type:
Refer to manual for specific diesel engine oil viscosity and API classification (e.g., SAE 15W-40 API CD/CE or higher)
Type:
Likely a fully synchronized gearbox with multiple forward and reverse speeds (e.g., 12x12 or 18x18 with creeper gears)
Powershift:
Possible availability of a powershift (e.g., 16x16 with powershift increments) depending on specific configuration.
Clutch:
Dual-stage dry clutch for transmission and PTO engagement
Pto Speeds:
Standard PTO speeds (e.g., 540/1000 RPM), possibly ground speed PTO
Transmission Oil Type:
Refer to manual for specific transmission/hydraulic fluid (e.g., UTTO - Universal Tractor Transmission Oil)
Engine Oil Change:
Refer to manual (typically 250-500 operating hours)
Transmission Hydraulic Filter:
Refer to manual (typically 500-1000 operating hours)
