BSA 'Service Sheets' Master Catalogue for All Models 1945 to 1967

More than 550 illustrations and charts, size 8.25x10.75 inches.


In 1945, after the war had ended, BSA resumed production of their civilian line of motorcycles. However, they continued their pre-war practice of publishing repair, overhaul and technical information in the form of individual 'Service Sheets'. It should be noted that BSA never intended that these service sheets would be distributed to the general public, they were 'dealer only' publications and the print quality was at times somewhat questionable. It was not until the early 1960's that BSA eventually started publishing model specific workshop manuals that were available to the general public. Consequently, these 'Service Sheets' were the only publications available for the maintenance and repair of BSA models that were manufactured through the mid 1960's.


The most complete compilation of the 1945 and onwards service sheets was issued by BSA in the form of a 'dealer only' ringbinder that contained 166 individual service sheets (516 pgs) for the entire range of 1945 thru 1967 motorcycles. It is extremely difficult to find. It is this ring-bound publication that was used to create this 'Service Sheets Master Catalogue'. It includes every service sheet issued/updated by BSA from 1945 until the Service Sheet program was discontinued in the mid 1960's, models covered are as follows:





A7 & A10 1947-62


B31-B32-B33 and B34 1945-60 (Inc. Gold Star & competition models)


C10-C10L-C11-C11G and C12 1945-58


C15-C15T-C15S-C15SS and B40 1958-67


D1-D3-D5 and D7 (Bantam) 1948-66


M20-M21 and M33 1945-63


Dandy 1956-62





At some point in the 1930's, BSA adopted the practice of identifying their various model types by 'groups' and the models manufactured from 1945 through the mid 1960's were in Groups A, B, C, D and M. The service sheets that were associated to a particular group were identified numerically and, while there were some exceptions due to overlapping data between models, in general terms the numbers relate to a particular model group. They are as follows: The 200 series of service sheets were applicable to Group A models, the 300 series to Group B, the 400 series to Group C, the 500 series to Group D and the 600 series to Group M. In addition, there were a 700 series applicable to mechanical maintenance and an 800 series for electronic service and wiring diagrams. Both the 700 and 800 series of service sheets contained information that was not model specific but was applicable across multiple model groups. Finally, there were a 900 series for the BSA Dandy and a 1000 series for the BSA Sunbeam and Triumph Tigress scooter. The 1000 series sheets were published under the generic title, 'Scooter Service Sheet'. These sheets did not display either company logo and they were never intended to be included in the ring-bound dealer album.





Unfortunately, as these service sheets were issued individually and at random times, the numbering sequence within any group is, at times, illogical and not necessarily consecutive. Consequently, owners of BSA motorcycles are subjected to considerable confusion surrounding the appropriate selection from the multitude of reprints that have recently flooded the online marketplace. Many of the reprints found on internet websites are from 'bedroom sellers' at enticingly low prices by individuals that really have no idea what they are selling. Many are nothing more than poor quality comb-bound photocopies that are scanned and printed complete with greasy pages and thumbprints and are deceptively described as 'pre-owned', 'used' or even 'refurbished'! In addition, they are often advertised for the incorrect series and/or model years of motorcycles.
