Set of Three Training Guides for 1980s Diesel Engines.

For the size of these three manuals, the good usable information inside is humongous. If you have one of these diesels, these will get you up to speed and help you get your diesel running better. These were delivered to factory dealerships to help their mechanics with pre-glow systems, diesel fuel injection systems, and diesel engine theory and troubleshooting. This set is very hard to find.
