Vols 1 – 13

1927 – 39 

7hp Models





These articles are taken from a book of extracts.  The pages were in sequence in a bound volume but have the page numbers of the original sections as issued at intervals over the years.  There is no indication as the date of publication or by whom; however the original copyright is with the Austin Motor Co. Ltd.

The Service Journal consisted of articles covering all models of Austins in production at that time as the servicing techniques were often the same.  There were also many pages of revised part numbers, special tools, and short updates of how a task should be undertaken by mechanics.  These have very little, or no, relevance to the present day diy enthusiast and so have not been reproduced here. 

The articles have been selected for their detailed information on how to do the task.  They are in chronological order of publication with the month/year on the pages to enable the reader to ensure that it is relevant to their model.  Please note that references to firm’s names and addresses, and many specified products, are now completely out of date.  

Some pages refer to page numbers of a previous article; these are in the original full edition of the Journal and have not been included in the Extracts from which these articles have been taken; therefore, they cannot be included or cross-referenced.  As far as possible links are given to other articles on the same topic on this website.

All pages have been scanned at 600dpi and can be copied onto a blank page in MS Word or Publisher and made to fit the page for your own use.  Unfortunately some of the pages in the Extracts were of poor quality and the reproduction here is the best which can be achieved.

You may wish to consider referring to The Austin Seven Manual.
Fully recommended for the d-i-y enthusiast.  This is an all embracing workshop manual covering 'Seven' models from 1925 to 1939, but does not adequately cover the 'Big Seven'.  The sections deal with the Engine; Fuel System; Gearbox; Prop Shaft; Rear Axle; Front Suspension; Steering; Hubs & Brakes; Road Springs; Chassis; Electrical, and Accessories.  Each section is divided into periods ie 1923-28, 1928-1932, 1932-35, although not always these years.  Within each section are subsections on Dismantling and Assembly.  Diagrams support the step by step easy to follow text, but the only problem is that the text does not cite the letter identifying the part in the diagram, so there is a need to have a reasonable technical knowledge in order to use it.  by the late Doug Woodrow, published by and available from Mercury Vintage Services, Rosedale, Station Road, Emneth, Norfolk PE14 8DL.  Tel: 01945 430058  e-mail:
