⚙️ Engine Specifications

Primary Engine

Engine Options:

The Kerax range typically featured Renault's dCi engines, specifically variants of the larger displacement diesel engines suitable for heavy-duty applications. Common engines included inline 6-cylinder turbocharged and intercooled diesel engines, with displacements often in the range of 10.8L to 12.8L. Specific engine codes like MIDR 06.xxx.xx (e.g., MIDR 06.20.40) were used.

Engine Family:

Typically built around Renault's powerful dCi engine family, specifically designed for heavy-duty commercial use. Examples include engines from the MIDR (Motori Italiani Diesel Renault) series.

Performance

Horsepower Range:

Horsepower ratings for the Kerax series typically ranged from approximately 300 hp to over 450 hp, depending on the specific engine variant and model configuration.

Torque Range:

Torque figures were substantial, commonly ranging from 1200 Nm to over 2000 Nm, essential for hauling heavy loads and operating in challenging terrains.

Engine Displacement Examples:

Common displacements include 10.8 liters (e.g., MIDR 06.20.40) and 11.1 liters, with potential for larger variants depending on the specific Kerax variant and market. Some models may have utilized 12.8 liter engines.

Fuel System

Fuel System Type:

Commonly employed electronically controlled unit injectors (PDE) or common rail (CR) fuel injection systems, designed for high pressure and precise fuel delivery.

🔧 Transmission

Standard

Standard Transmission Type:

Heavy-duty manual transmissions were common, often from ZF or similar manufacturers, with 16-speed configurations. Automatic or automated manual transmissions (like Renault's Optidriver+) were also available on some variants.

Optional

Optional Transmission Type:

Automated Manual Transmissions (AMT) were often offered as an option for improved drivability and fuel efficiency, especially in long-haul or mixed-application models.

Features

Clutch Type:

Typically a single-plate dry clutch, engineered for the high torque loads encountered in heavy-duty service.

Gear Ratios:

Detailed gear ratios for both forward and reverse gears, crucial for understanding the vehicle's tractive effort and speed capabilities in different gears. These vary based on transmission model and application.

📐 Dimensions

Exterior

Wheelbase Options:

Various wheelbase configurations were available to suit different applications, ranging from standard rigid truck chassis to tractor units for semi-trailers. Specific lengths varied significantly.

Gross Vehicle Weight Rating Gvwr:

GVWRs for the Kerax range could extend up to 40 tonnes and beyond, depending on the axle configuration (e.g., 8x4, 6x4).

Chassis Configurations:

Available in various configurations including 4x2, 4x4, 6x4, 6x6, 8x4, and 8x8, providing flexibility for diverse operational requirements. This manual covers steering for all these configurations.

Weights

Front Axle Load Capacity:

Front axle capacities were substantial, often rated between 7.5 to 9 tonnes or more, reflecting the heavy-duty nature of the vehicle.

Rear Axle Load Capacity:

Rear axle capacities were correspondingly high, frequently ranging from 13 to 26 tonnes or more, often with tandem or tridem configurations.

🛡️ Safety Features

Ratings

Crash Test Results:

Commercial trucks like the Kerax are subject to different safety regulations and testing than passenger cars. Emphasis is placed on cab integrity, driver protection in frontal and side impacts, and rollover stability. Specific ratings depend on region and regulatory standards at the time of manufacture.

Active Features

Braking System:

Typically equipped with a full air brake system (S-cam or disc brakes) with ABS (Anti-lock Braking System) and potentially ASR (Anti-Slip Regulation) for enhanced control under acceleration.

Passive Features

Cab Construction:

Reinforced safety cab structure designed to protect the driver in the event of a collision or rollover, with features like energy-absorbing crumple zones and roll-over protection.

💡 Technology Features

Infotainment

Infotainment Systems:

Basic infotainment systems of the era, typically including AM/FM radio, CD player, and potentially an auxiliary input. More advanced features were less common in construction-focused variants compared to long-haul trucks.

Driver Assistance

Driver Assistance Features:

Features relevant to steering would include power steering itself. Advanced driver-assistance systems (ADAS) as seen in modern vehicles were generally not prevalent on Kerax models, but ABS was standard.

Connectivity

Connectivity Options:

Limited connectivity, primarily focused on vehicle diagnostics and potentially tachograph integration. Bluetooth or advanced telematics were less common.

🔧 Maintenance

Service Intervals

Steering Fluid Change Interval:

Intervals for steering fluid and filter changes typically range from 30,000 to 60,000 km (18,000 to 36,000 miles) or annually, but this should be confirmed with the specific vehicle's operating conditions and the manual's recommendations.

Steering System Inspection Interval:

Visual inspection of steering linkage, boots, and fluid levels recommended at every major service interval, typically every 15,000-30,000 km (9,000-18,000 miles).

Fluid Specifications

Steering Fluid Type:

Typically requires a high-quality hydraulic fluid suitable for power steering systems, such as Dexron III/VI compatible fluids or specific mineral oil-based hydraulic fluids. Consult the manual for the precise Renault specification (e.g., Renaultmatic D3 or similar).

Steering Fluid Capacity:

Fluid capacity varies by model and steering gear type but is generally in the range of 2 to 5 liters for the power steering system. The manual will provide the exact capacity.

Known Issues

Common Steering Issues:

Potential issues include leaks from steering gear seals or hydraulic lines, wear in steering column universal joints, premature wear of the power steering pump (leading to stiffness or whining), and loose tie rod ends or kingpins causing play and affecting tire wear. Fluid contamination can also damage components.

Wheel Alignment Drift:

Due to the heavy-duty and often off-road use, wheel alignment can drift. Regular checks and adjustments are crucial to maintain steering stability and tire life.

Power Steering Fluid Contamination:

Contamination from wear particles or water ingress can accelerate wear in the pump and gearbox. The manual details fluid testing and flushing procedures.
