Technical Service Bulletins

 

These documents are in PDF Format and hosted here for historical reference.

These documents may be copyrighted by the British Motor Industry Heritage Trust. they are confidential internally circulated bullitins from the factory to Austin MG dealerships. Spridget related TSBs are indexed into the tech index catagories, but here is the complete listing. Bulletins are in roughly chronological order. Ealier BMC era bulletins have TSB ID numbers where the first two digits indicate in what order this tsb was issued (i.e. the 32nd tsb or 64th or whatever), and the last two indicate the year in which the tsb was issued. On British Leyland era bulletins the first two digits of the TSB ID number indicate the model year of publication. The letter in the third place is the group category (B is electrical for example). Some bulletins apply to all models and as such they are included in all three listings.
