260 pages and more than 290 illustrations and charts, size 8.25 x 10.75 inches. This publication is a reproduction of the Triumph factory workshop manual part number 99-0843/0948/0950.
The original workshop manual part number 99-0843 was subsequently updated and merged with workshop manual 99-0948. This merged 'double' manual also included a supplement, part number 99-0950 which extended the coverage up to the 1974 models. The supplement was appended to the 'double' manual such that 'Section A - Lubrication System' is followed by a 'Section AA - Lubrication System' supplement and 'Section B - Engine' is followed by a 'Section BB - Engine' supplement, etc., etc. This combination of 99-0843/0948/0950 was published as a single workshop manual applicable to the entire range of 350cc and 500cc unit construction twins from 1963 through 1974. This reprint is a faithful reproduction of that 'combination' manual.
There were a number of 'running changes' made throughout the 11-year production run of these models and the way the factory identifies the point where those changes took place is by referencing engine numbers within each individual section of this manual. To assist in identifying the appropriate information applicable to those changes, the supplements were appended to the end of each appropriate section. Consequently, it is important to note, with regard to any maintenance and repair instructions and also the specifications in the 'General Data' (GD) section, that wherever engine numbers are stated, the data will be specific to that particular series. Therefore, the reader is encouraged to read the entire section plus the supplemental section prior to commencing any work, paying close attention to any engine number notations.
Owners of the 350cc and 500cc machines are subjected to considerable confusion surrounding the appropriate selection of the multitude of originals and reprints of the various 350cc and 500cc manuals that have recently flooded the online marketplace. Based on our research, at least six manuals were issued for different series of engine numbers throughout the 11-year production run. However, the 99-0843/0948/0950 'combination' manual is the most comprehensive manual for the entire line of 350cc and 500cc unit construction twins produced from 1963 to 1974. It covers all engine numbers from H29733 through H67331 plus the later 1969 through 1974 alpha numeric series engine numbers, unfortunately, it is somewhat scarce and difficult to find. In addition, many of the changes made towards the end of the production run necessitate the use of the supplement and we are pleased to offer this reprint of the 'combination' manual as a service to all Triumph 350cc and 500cc unit construction owners. The 1963 to 1974 models covered are:
Tiger 100: T100SS Tiger (1963-1965), T100 Tiger (1966), T100S Tiger (1967-1970), T100T & T100R Daytona (1966-1974), T100C Trophy (1966-1972)
Speed Twin: 5TA (1963-1966)
Tiger 90: T90 (1963-1969)
Twenty One: 3TA (1963-1966)
