Manual Extract: PFC HYDRAULIC PUMP TROUBLESHOOTING

The powershift is the system used to change gears 1 to 4 without needing to cycle the inching pedal. The movements of the powershift transmission lever are converted into electrical signals at the shifter assembly and transmitted to the powershift control module. The powershift control module receives electrical signals both from the shifter assembly and from the pressure switches in the powershift manifold. Dependent upon the electrical signals received, the powershift control module operates solenoids in the powershift manifold. The solenoids operate the hydraulic circuits that control the clutches of gears 1 to 4.

Faults in the powershift system may be hydraulic or electrical. Hydraulic faults in other systems may also prevent correct operation of the powershift system. If a fault occurs in the powershift system the powershift control module will detect
the fault and select a fail mode. There are two fail modes (Drive) and (Stop), in the Drive fail mode the module will remain
in the current speed (A) after a change is made to the selected speed (B), this will allow the tractor to be driven to a place
of repair. If the module detects a fault that will cause damage to the transmission the module will select the Stop mode
and the tractor cannot be driven.
