The Service Instruction Manuals are extremely rare. Virtually all of the material on this page is a result of Club Members lending items for scanning, so a big thank you to everyone who has helped make this resource possible. These are scans of the best copies which are currently available.
Manuals
The information builds year-on-year so read the issues for the model years prior in addition to your car's model year.
Engineering Drawings
The earlier manuals included engineering drawings. You may need to look at the the drawings for previous years' models if later models are basically similar. For example the 1932 Little nine engine was the basis of the nine engines until 1936. Some drawings are repeated in subsequent years but used on different models.
Where shown, the figures in circles give the drawing and Standard part numbers for the parts indicated. The part numbers can be cross-referenced with those given in the Parts Lists to establish interchangeability between different model years.
