⚙️ Engine Specifications

Engine Model Bd2G:

Typically a Mitsubishi 2-cylinder diesel engine (e.g., KM2 series variants).

Engine Model Bs3G:

Likely a Mitsubishi 3-cylinder diesel engine (e.g., KM3 series variants) for increased power with the loader.

Horsepower Bd2G:

Approximately 15-25 HP (exact figures vary by sub-model and year).

Horsepower Bs3G:

Approximately 25-35 HP (exact figures vary by sub-model and year).

Fuel Type:

Diesel

Injection System:

Direct injection or indirect injection (specifics in manual).

Cooling Method:

Liquid-cooled

Oil Type Recommendation:

API CE or CF classification diesel engine oil, SAE 10W-30 or 10W-40 (refer to manual for exact specifications and viscosity grades based on temperature).

🔧 Transmission

Transmission Type:

Manual transmission with multiple forward and reverse gears, often with a range selector (Hi/Lo).

Optional Features:

Some models may have offered partial powershift or shuttle shift functionalities (verify with manual).

Power Take Off Pto:

Rear PTO, typically 540 RPM, and potentially a mid-PTO for the loader/shovels.

Transmission Oil Type:

API GL-4 or GL-5 gear oil, SAE 80W-90 or 85W-140 (verify specific type and capacity in manual).

📐 Dimensions

Wheelbase:

Varies by specific model configuration, typically 1500-1800 mm.

Overall Length:

Varies by specific model configuration, often 2800-3500 mm (excluding loader attachments).

Overall Width:

Varies by specific model configuration, typically 1300-1600 mm.
