This is the I&T shop service manual for the Allis-Chalmers tractors models D-10 and D-12. I&T manuals are very handy reference guides if you are working on your tractor. Primarily for mechanics, I&T manuals usually don't contain information on the safety or operating aspects of the tractor, but more on the individual working parts of the tractor. With plenty of exploded parts views and other pictures this manual is perfect for the restorer or mechanic. Just print it out, put it in a binder and get to work fixing your D-10 or D-12!
