This is the factory workshop manual for the SAME Rubin 120, Rubin 135, and Rubin 150 tractors, powered by the 1000.6 WT and 1000.6 WTI diesel engines. It runs 812 pages of repair, overhaul, and diagnostic procedures written for service technicians.
Coverage runs the full machine: the open-centre and load-sensing hydraulic systems, control valves, power steering and trailer braking, the power shift transmission with its H-M-L unit and axles, front and rear PTO, power lift, and the hydraulic front axle suspension. It also includes the ECU tester procedures for the engine, transmission, lift, and armrest controllers, plus full electrical diagrams.
From bleeding the brakes and calibrating the electro-hydraulics to a complete transmission or PTO clutch overhaul, it gives the tightening torques, clearances, and step-by-step methods for working on your Rubin.
