Engine Type:
Inline 4-cylinder, OHV, transverse mounting
Displacement Options:
Primarily 850cc (848cc) and 1071cc (for Cooper S), with later 998cc and 1275cc variants appearing in later Mk1 and Mk2 models. The manual likely covers the range relevant to Mk1.
Horsepower Range:
Approximately 34-38 hp for 850cc, 55-70 hp for Cooper models, and up to 77 hp for early 1071cc Cooper S models.
Torque Range:
Specific torque figures vary by engine variant, typically between 50-70 lb-ft for standard models and higher for Cooper S variants.
Carburetion:
Primarily single SU carburetors (e.g., HS2 for 850cc, HS2 or HS4 for 1071cc/998cc Cooper), with twin carburetors on performance models.
Oil Change Interval:
Typically every 3,000 miles or 6 months, using a specific oil specification.
Grease Points:
Regular chassis greasing at key suspension and steering points is crucial, often on a mileage-based schedule (e.g., every 1,000-2,000 miles).
Engine Oil Type:
Historically, straight-weight oils (e.g., SAE 20W/50 or 20W/30 depending on climate) were recommended. Modern formulation API SG or higher is suitable, but care should be taken with additives for older engines (e.g., ZDDP content for flat-tappet camshafts).
Transmission Oil Type:
Gearbox oil is shared with the engine oil (common oil). Capacity is approximately 2.5 Imperial pints (1.4 Litres).
Coolant Type:
A mixture of distilled water and anti-freeze (e.g., ethylene glycol based) is required. Capacity around 5.5 Imperial pints (3.1 Litres).
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid is typically specified.
Rust And Corrosion:
Prone to rust, particularly in wheel arches, sills, floor pans, and boot floor. Regular inspection and rust prevention are vital.
Hydrolastic Suspension:
Requires specific expertise for maintenance and adjustment; fluid levels and pressure need regular checking.
Carburetor Tuning:
SU carburetors require periodic adjustment and rebuilding for optimal performance and fuel economy.
Gearbox Synchromesh:
Early models may have less robust synchromesh, requiring careful gear changes.
Brand Origin:
British Motor Corporation (BMC), designed by Sir Alec Issigonis.
Design Philosophy:
Revolutionary transverse engine and front-wheel-drive layout, maximizing interior space within a small footprint.
Key Variants:
Standard (850cc), Cooper (998cc, 1071cc, 1275cc), Riley Elf, Wolseley Hornet, Traveller (estate), Countryman (long-wheelbase estate).
Manufacturing Locations:
Primarily Longbridge, Birmingham, UK; also produced under license in various countries.
