Typically 2.0L to 4.0L, depending on specific engine model used.

Power Output:

Horsepower ratings commonly range from 35-65 HP (26-48 kW) for this class of forklift.

Torque Output:

Torque figures would be optimized for lifting and low-speed operation, typically in the 100-150 lb-ft (135-200 Nm) range.

Diesel Fuel System:

High-pressure common rail (HPCR) or older distributor-type injection systems, depending on the engine generation.

Lpg Fuel System:

Carbureted or fuel-injected LPG systems with appropriate vaporizers and mixers.

Cooling Type:

Liquid-cooled with radiator, fan, and thermostat.

Oil Type Diesel:

API CJ-4 or CK-4 rated diesel engine oil, typically SAE 15W-40 or 10W-30, depending on ambient temperature. (Refer to specific engine manual for exact spec).

Oil Type Lpg:

API SN or similar gasoline engine oil, typically SAE 10W-30 or 10W-40. (Refer to specific engine manual for exact spec).

🔧 Transmission

Type Standard:

Likely a hydrostatic transmission (HST) or a torque converter automatic transmission (AT) for smooth operation and variable speed control.

Type Optional:

While less common in this capacity, a manual transmission could be an option in some older or specialized configurations.

Drive Modes:

Single or dual speed drive modes for optimized power delivery.

Hydraulic Control:

Electronically or hydraulically controlled for precise acceleration and deceleration.

Transmission Fluid Type:

Dexron III/Mercon equivalent ATF (Automatic Transmission Fluid) or specific manufacturer-approved hydraulic fluid, depending on transmission type. (Refer to manual for exact specification and capacity).

📐 Dimensions
