This is the factory chassis service manual for the McCormick MTX Series tractors: the MTX110, MTX120, MTX125, MTX135, MTX140, MTX150, MTX155 and MTX165. It runs 1,602 pages across the factory two volume set (publication SM 8-11504) and is the book the dealer technician works from. It covers the tractor, the powershift and range transmission, the front and rear axles, the hydraulics, the steering, brakes, cab and the full suite of electronic controllers, with complete electrical troubleshooting and schematics (separate diagrams for the different model groups) and hydraulic schematics, plus step by step calibration and error code procedures for every controller on the tractor. One honest note up front: internal engine teardown and overhaul are not in this volume. The engine section covers removal and refitting and points you to the companion McCormick engine manual for the rebuild. Everything else on the machine is here.
