Thanks to Tom, the Monarch came with more documents than some. Being the gearhead that I am, I'm collecting documents for the other systems and components.

We have good stuff here for the Allison MD3060 but not much for the 8.3 Cummins. I found this on Ebay:
"Operations and Maintenance Manual C Series Engines" It has all regular maintenance and some repair of accessories covered. 1993 edition but about right for our vintage rigs.

Since I had nothing better to do on a rainy day, I scanned most, left out the troubleshooting flow charts and the service locations, etc. It was a half page format, over 200 pages. I scanned 2/page still over 100 pages.

If you print it on soft paper it will last a while in the "library"
