Why Accurate Hydraulic Adjustment Matters

The Selectamatic hydraulic system is one of the defining features of these tractors. Smooth hitch operation depends on correctly adjusted valves, linkage geometry and hydraulic pressure. Likewise, clutch wear, steering play and gearbox components should always be inspected before major parts are replaced. Following the factory repair sequence helps identify the real source of a problem while avoiding unnecessary repairs.

This workshop manual guides technicians through every stage of servicing, beginning with fault diagnosis and inspection before moving to dismantling, component measurement, rebuilding, calibration and operational verification.
