⚙️ Engine Specifications

Engine Type And Variants:

Likely equipped with Mercedes-Benz's OM601 or OM602 series diesel engines. These are typically inline-four or inline-five cylinder naturally aspirated or turbocharged indirect injection (IDI) or direct injection (DI) diesel engines. Specific displacement could range from approximately 2.3L to 2.9L.

Typical Performance Figures:

Horsepower generally ranged from 70 to over 100 hp, with torque figures suitable for commercial load carrying. Turbocharged variants would offer more significant power and torque gains. Exact figures vary by engine code and specific model year.

Torque Delivery Characteristics:

Diesel engines of this era typically offer strong low-end torque, making them well-suited for pulling away from a standstill with loads or for towing applications.

Fuel System Description:

Primarily Bosch inline injection pumps (e.g., VE type) for naturally aspirated versions and potentially rotary pumps or electronically controlled injection pumps for turbocharged variants. Fuel filters are critical maintenance items.

Common Engine Codes And Types:

OM601 (e.g., OM601.940 - 2.3L Diesel), OM602 (e.g., OM602.940 - 2.9L Diesel). These engines are known for their longevity and robustness, often requiring minimal electronic control. Turbocharged variants (e.g., 310 TD) would be identified by 'TD' designation.

🔧 Transmission

Standard Transmission Type:

Most likely a 5-speed manual transmission. Robust and designed for commercial use.

Optional Transmission Type:

An automatic transmission may have been an option on certain higher-spec models, but manual was likely the predominant choice.

Transmission Features:

Rear-wheel drive, robust gearing for load-carrying capacity, potentially a locking differential option for improved traction.

Gear Ratio Information:

While specific ratios are not listed, manual transmissions would have carefully selected gear ratios to balance performance with load-carrying ability, typically featuring lower first gears for starting under load and overdrive gears for efficient highway cruising.

📐 Dimensions

Exterior Dimensions General:

Dimensions vary significantly based on body style (panel van, chassis cab, crew van) and wheelbase. Panel vans typically offer substantial cargo volume. Lengths could range from approximately 4.5 to 6 meters. Width typically around 2 meters. Height varies significantly for van body styles.

Interior Dimensions General:

Cab space designed for driver and passenger comfort for long working days. Cargo area dimensions depend entirely on the specific body configuration, designed for maximum utility.
