⚙️ Engine Specifications

Primary Engine Options:

Likely includes 2.25L petrol (1579E/1595cc), 2.25L diesel (2050cc), and potentially 2.6L petrol (2625cc) variants. Specific engine codes and configurations detailed within the manual.

Engine Families:

Rover IOA (petrol) and Rover IDI (diesel) families, with specific displacements of 2.25L and 2.6L.

Typical Horsepower:

Approx. 60-70 hp for 2.25L petrol, approx. 50-60 hp for 2.25L diesel, approx. 90-100 hp for 2.6L petrol. (Exact figures vary by year and specific engine code).

Engine Variants Covered:

Includes detailed specifications for the 2.25L petrol, 2.25L diesel, and 2.6L petrol engines common in the Series 3.

Fuel System Types:

Carbureted for petrol engines, typically Zenith or SU carburetors. Diesel engines use injection pumps and injectors. Manual details specific fuel system components and procedures.

Diesel Fuel System:

Covers injection pump timing, injector servicing, and fuel filter replacement for diesel models.

🔧 Transmission

Standard Transmission:

4-speed manual (synchromesh on 2nd, 3rd, and 4th gears).

Optional Transmission:

Rarely, some Series 3 might have had overdrive units fitted as an aftermarket or dealer option, but not a factory-selectable alternative transmission. Transfer case is a key component.

Transmission Features:

Robust, part-time 4-wheel drive system with a central differential lock (selectable). Manual details clutch operation, gearbox servicing, and transfer case maintenance.

Transfer Case:

Robust twin-lever 4-wheel drive transfer case with high/low range selection. Manual covers servicing, maintenance, and potential repairs.

📐 Dimensions

Wheelbase Options:

Short Wheelbase (SWB) - 88 inches, Long Wheelbase (LWB) - 109 inches. Later models may include 110 chassis, but this manual specifically covers up to 1981, which predominantly signifies the 109 and earlier 110 configurations derived from Series 3 design elements.

Body Styles Covered:

Station Wagon, Utility (Hardtop), Soft Top, Pickup Truck, Ambulance, etc., reflecting the versatility of the Series 3 platform.

Gross Vehicle Weight:

🛡️ Safety Features

Safety Ratings:

Safety standards of the era were significantly different. The manual will detail the vehicle's inherent safety features and structural integrity for its time, not modern crash ratings.

Active Safety Features:

Four-wheel drive system for enhanced traction, robust braking system (drum brakes on most models, disc front brakes introduced later in the Series 3 run).

Passive Safety Features:

Body-on-frame construction, basic seat belts (may be lap belts depending on year/market), limited interior padding.
