The factory workshop manual for the Austin Healey 100/4 (BN1 and BN2) provides the most authoritative reference for maintaining and repairing early Healeys. Compiled by the original BMC service department, this book includes period-correct diagrams, torque figures, and procedures exactly as mechanics would have used when the cars were new.
Note: This manual covers standard BN1 and BN2 specification cars. Factory instructions for the Le Mans (M-spec) upgrade were issued separately and are not included here.
This manual applies to all Austin Healey 100/4 BN1 and BN2 models, including production changes across the range. Owners of cars with later modifications may find additional cross-reference required.
Unlike third-party handbooks, this official manual captures the exact methods specified at the time of production, ensuring restorers follow the correct service practices. It also helps identify the correct part numbers and sequences when working with original or replacement components.
This is a high-quality reproduction of the original BMC workshop manual, ensuring all content is legible and true to the factory layout.
