Electric Clutches

There are two electric clutches that connect the engine to the water pump and the cycling valve.

When the operator depresses the ENGAGE button, the first clutch energizes, engaging the water pump.

After the water pump builds the required pressure, the control module engages the second clutch, engaging the

cycling valve and starting the aeration cycle.

If at any time the water supply pressure drops below 15-20 PSI or if the traction unit stops, the water pump

clutch and cycling valve will disengage.

Electric Clutch Testing and Adjustment

Both clutches should measure 3 Ohms of resistance across the coil when tested with an Ohmmeter.

For the clutches to operate properly the correct air gap must be maintained.

The air gap is checked with a feeler gauge and set to .018”.
