Steam generator operation, electrical equipment, troubleshooting and truck removal are covered in this third and final installment of the E7 operating manual. The veteran hoggers and firemen must have been thrilled to have to learn how to 'make steam' all over again - using the complex steam generators.
The other two sections of this manual can be found in the index Railway Technology & Systems 04 (button above). This and other manuals can be found under the heading Diesels, The First Generation.
The loose-leaf binder holding this 70 year old manual would not open, so I used the expedient of scanning a two-page spread for most images.
The diagram above is shown at what you could call GoogleMax (the maximum image display size after it is uploaded to Google).
To make it possible to read the details, the diagram is split and presented in two halves below.
Look for the overlap - which duplicates the 'fuel pumps' location at centre/bottom (above).
End of manual.

In the first part of this series, I explained the unlikely
north shore of Lake Superior provenance of my particular E7 manual.
E7 locomotives were not purchased by Canadian railways.
Here are the sales figures for some of the EMD E-units.

Early Trains magazines were surprisingly non-specific when it came to nailing down the builders' models of diesel locomotives in articles and photo captions ... at least by today's standards. An E7 was used on the GM Train of Tomorrow. The latter has an excellent, detailed article on Wikipedia.

My father attended (he won it through a Montreal Star competition) a teacher's summer course and travelled to Syracuse University in July 1961. The course was on the use of newspapers as teaching aids in the classroom. He travelled to Syracuse, New York by bus because we didn't own a car and also because the bus got him there conveniently.
My father 'happened' to visit the Syracuse station and took this slide of the DeWitt Clinton (a named train) westbound. An E8 leads and perhaps there is an E7 trailing. With 4000 horsepower for what looks like mainly mail and express, they probably got over the road quite efficiently.
