The Mini Mark British Leyland Austin-Morris PICK-UP 1957-1965 represents one of the most iconic and enduringly popular commercial vehicle designs of the 20th century. Based on Sir Alec Issigonis revolutionary Mini platform, the Mini Pick-Up combined the groundbreaking transverse-engine front-wheel-drive architecture with a practical cargo bed, creating a vehicle that was equally at home making deliveries in the narrow streets of London or navigating farm lanes. Its compact dimensions of just over 10 feet in length and remarkably light weight made it astonishingly nimble and economical to run.
Under the diminutive bonnet lies the classic BMC A-series inline four-cylinder engine, typically the 848 cc or 998 cc variant depending on production year, paired with a four-speed all-synchromesh manual gearbox integral with the engine sump in the famous "package deal" arrangement. The Mini Pick-Up was exported worldwide and remains highly sought after by collectors and enthusiasts today, celebrated for its character, simplicity, and the genius of Issigonis packaging.
VEHICLE/EQUIPMENT INTRODUCTION
The Mini Mark British Leyland Austin-Morris PICK-UP 1957-1965 represents one of the most iconic and enduringly popular commercial vehicle designs of the 20th century. Based on Sir Alec Issigonis's revolutionary Mini platform, the Mini Pick-Up was introduced by the British Motor Corporation (BMC) in 1961 and continued through the Austin-Morris era of British Leyland until 1965 (the platform itself continued in production with updates for decades afterward). The Mini Pick-Up combined the Mini's groundbreaking transverse-engine front-wheel-drive architecture with a practical cargo bed, creating a vehicle that was equally at home making deliveries in the narrow streets of London or navigating farm lanes in the Cotswolds. Its compact dimensions -- just over 10 feet in length -- and remarkably light weight (approximately 1,300 lbs) made it astonishingly nimble and economical to run.
Under the diminutive bonnet lies the classic BMC A-series inline four-cylinder engine, typically the 848 cc or 998 cc variant depending on production year, paired with a four-speed all-synchromesh manual gearbox integral with the engine sump in the famous "package deal" arrangement. The Mini's rubber cone suspension (early models) or Hydrolastic interconnected fluid displacement system (later models) provided a ride quality far beyond what the vehicle's utilitarian appearance suggested. Drum brakes on all four wheels, operated by a single-circuit hydraulic system, provided adequate stopping -- later models received upgraded servo assist and dual-circuit systems. The Mini Pick-Up was exported worldwide and remains highly sought after by collectors and enthusiasts today, celebrated for its character, simplicity, and the genius of Issigonis's packaging.
This service repair workshop manual covers the Mini Mark Austin-Morris PICK-UP from 1957 through 1965, providing comprehensive procedures for engine overhaul, gearbox service, suspension work (both rubber cone and Hydrolastic variants), brake system rebuilding, electrical system troubleshooting, and body restoration. Whether you are performing a nut-and-bolt restoration on a barn-find Pick-Up or keeping a daily driver in peak condition, this manual provides the factory-level specifications and illustrated instructions needed to do the job correctly.

DIAGNOSTIC INFORMATION
This manual contains methodical diagnostic procedures for every common ailment on the Mini Pick-Up. Hard or no-start conditions are traced through verification of fuel delivery at the carburetor (removing the dashpot damper and observing the float chamber), spark quality (pulling a HT lead and holding it near a grounded surface while cranking), and compression (minimum target values and allowable inter-cylinder spread). The SU carburetor section provides a dedicated tuning procedure to achieve the correct air-fuel mixture using the lifting-pin method. Oil pressure problems are diagnosed by fitting a mechanical gauge to the oil pressure switch port and comparing readings against the factory specification chart at idle and at 3,000 RPM. Brake diagnosis distinguishes between fluid leak (check wheel cylinder boots for wetness), air in system (spongy pedal), and worn shoes (pedal travel increases). The Hydrolastic suspension section describes how to diagnose displacer diaphragm rupture by observing height collapse on one corner, and how to pressure-test the interconnecting system. Electrical faults are traced using the detailed Lucas wiring diagrams with color-coded wire identification.
