Diesel, 4-cylinder, overhead valve
Horsepower Approx:
Approximately 39-45 PTO horsepower, depending on specific engine tuning and variant.
Torque Approx:
Torque figures vary, but generally robust for its class.
Injection System:
Typically rotary or inline injection pump (e.g., CAV, Simms) and direct injection.
Engine Oil Change:
Typically every 100-200 operating hours or annually, depending on operating conditions.
Fuel Filter Replacement:
As per manual, usually at scheduled intervals or when performance issues arise.
Air Filter Cleaning Or Replacement:
Frequent checks and cleaning/replacement recommended, especially in dusty environments.
Engine Oil Grade:
SAE 30 or 10W-30 Diesel Engine Oil (check specific manual for exact recommendation).
