This is the Kubota factory workshop manual covering the M4500, M5500 and M7500 tractors in both A and AC versions, in 2WD and 4WD (DT) configurations, powered by the Kubota S2600-A, D3000-A and V4000-A diesel engines. Across 251 pages it documents every driveline and chassis system: the dual clutch, the gear transmission with Hi-Lo and creep ranges, the rear axle and differential, wet disc brakes, front axle, power steering, the hydraulic lift system, electrical circuits and tires.
Each area is covered twice, once as a mechanism description and once as a servicing chapter with troubleshooting, specifications, tightening torques and full disassembly and assembly procedures. Real figures back the work, such as the 50.0 L transmission fluid capacity, the 54 L fuel tank and the engine mounting bolt torque of 77.5 to 90.2 N-m.
It downloads instantly as a PDF you can print or read on any device.
