246 pages and more than 240 illustrations and charts, size 8.25 x 10.75 inches. This publication is a reproduction of the Triumph factory workshop manual part number 99-0963/0887/4223.
The original 1969 Trident workshop manual 99-0887 was updated in 1972 under part number 99-0963. A short time later, the introduction of a 5-speed gearbox (1972) and a front wheel disc brake (1973) necessitated the publication of a supplement 00-4223 which was then incorporated into the 99-0963 manual creating a single workshop manual for the 1968 through 1974 models. Unfortunately, the 99-0963 manual was also published without the 00-4223 supplement and the manual that includes the supplement can only be identified by the following notation printed to the bottom corner of the title page: 'PART NO. 99-0963 INCORPORATING 99-0887 AND SUPPLEMENT 00-4223'
The difference in content between the two manuals that carry the same part number is extremely important to owners of the 5-speed and disc brake models.
There were a number of 'running changes' made throughout the 6-year production run of these models and, in order to provide information applicable to those changes, the 00-4223 supplement was either merged or appended to the end of the appropriate sections within the manual. However, it is also important to note, with regard to any maintenance and repair instructions and also the specifications in the 'General Data' (GD) section, that whenever engine numbers are stated, the data will be specific to that particular series. Therefore, the reader is encouraged to pay close attention to any engine number notations and to read the entire section plus the supplemental data prior to commencing any work.
In conclusion, 750cc T150 and T150V owners are subjected to considerable confusion surrounding the appropriate selection of the multitude of originals and reprints of the various 750cc Trident manuals that have recently flooded the marketplace. However, the combination manual 99-0963/99-0887/00-4223 is the most comprehensive manual for the entire line of 750cc Trident three-cylinder motorcycles produced from 1968 through 1974, however, it is somewhat scarce and difficult to find. In addition, many of the changes made during the production run necessitate the use of this 'combination' manual and we are pleased to offer this reprint of the 99-0843/99-0948/00-4223 manual as a service to all 750cc T150, T150V owners. In addition, as the X75 Hurricane is a combination of both the Trident and the BSA Rocket 3 this manual will also be of interest to owners of that model.
The models covered are:
1968 to 1970 T150 Trident
1971 to 1972 T150 Trident
1972 to 1974 T150V Trident - with 5 speed gearbox and disc front brake.
