This is an ORIGINAL International Harvester Tractor Hydrostatic Transmission “Mobile Training Unit” Service Manual (1972 printing). Back in the early 1970’s International Harvester decided to bring the classroom to the IH dealerships for on-site training. That is where this manual came from. Very detailed information for working on hydro tansmissions. The condition of the cover is very good with NO tears or tatters. The book is tight and intact with NO loose or missing pages. Manual contains 125 clean pages plus several fold-outs (please see pics). NOT a cheap reprint. This manual is extremely rare and in VERY GOOD overall condition. FREE S & H. Thanks for viewing Triple K.
