Complete Factory Handbook for the BSA Model B20 500 c.c.

172 pgs, more than 240 illustrations and charts, size 8.25 x 10.75". 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'. These sheets were 'dealer only' publications and, as such, the print quality was somewhat questionable. It was not until the early 60'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 from 1945 through the mid 60's. At some point in the 1930's, BSA began identifying their various model types by 'groups' and the models manufactured from 1945 through the mid 60's were in Groups A, B, C, D and M. The service sheets were identified numerically and while there are some exceptions, 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. Also, there was 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. Unfortunately, as these service sheets were issued individually and at random times, the numbering sequence within a group is, at times, illogical and not necessarily consecutive. Consequently, assembling those individual sheets into a publication that serves as a model specific workshop manual is a somewhat difficult task and owners of BSA motorcycles are subjected to considerable confusion surrounding the appropriate selection from the multitude of reprints that have recently flooded the on-line 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. The most complete compilation of the 1945 and onwards service sheets was a BSA 'dealer only' ring binder that contained all of the individual service sheets totaling to almost 500 pages. This manual contains 51 service sheets(169 pgs) and includes 14 sheets(62 pgs) from that 'dealer only' publication plus the 37 service sheets(107 pgs) that were published by BSA under part number 00-4021. It covers the S.V. and O.H.V. rigid, spring frame, girder and telescoping fork M20, M21 and M33 models from 1945-63. Obviously, as the M20 and M21 were introduced in 1937, this manual will also be of use to owners of those earlier models. Please note that service sheets other than those in the 600 series that are included in this publication may also contain data that is applicable to 'other' model groups, as that was the original intention. For additional information the reader is directed to 'The Book of the BSA 250cc,350cc,500cc & 600cc OHV&SV singles 1945-1959' (ISBN 9781588502292) which covers the B31, B32, B33, B34, C10, C11, C11DL, M20, M21 & M33 models. The OHV 1955-1958 M33 models are also covered in 'The Book of the BSA OHV Singles 350cc & 500cc 1955-1967' (ISBN 9781588501561)

94 pages, 54 illustrations, size 5.5 x 8.5 inches. An illustrated Owner's Workshop Manual covering Pre-War BSA Single and Twin-Cylinder SV and OHV Motorcycles. This is a faithful reproduction of the Floyd Clymer (W.C. Haycraft) Book Of The BSA originally published in the US in 1947. Much more detailed than the owner's handbook, this manual includes complete technical data, service and maintenance information and detailed instructions for the repair and overhaul of the major mechanical and electrical components for the majority of the pre-war BSA single and twin cylinder motorcycles. However, as this manual was written specifically for the motorcycles constructed between 1936 through 1939 the information may not be quite as comprehensive for the earlier versions of these models. There is adequate detailed text and diagrams to assist in major refurbishing such as an engine rebuild or even a complete mechanical renovation, making it an invaluable resource for collectors and restorers of these classic BSA motorcycles. OHV and SV Models covered by this publication are: 150c.c. - X0. 250c.c. - B1, B2, B18, B20, B21, B22, C10, C11. 350c.c. - B23, B24, B25, B26, M19, R4, R5, R17, R19, R20. 500c.c. - J12, M20, M22, M23, M24, Q7, Q8, Q21, W6. 600c.c. - M10, M21. 750c.c. - Y13. 1,000c.c. - G14.
