MAINTENANCE (PUMP)

PUMP VACUUM TEST

CAUTION

DO NOT attempt to start the engine unless the pump has previously been primed with water. Severe pump damage will occur if pump has not been primed.

To perform the pump vacuum test do the following:

1.Remove the pump fill cap (See Figure 3), and fill the pump with water.

2.Start the engine as outlined in the initial start-up section, and wait for the pump to begin pumping.

3.As shown in Figure 18, place a water hose inside the discharge opening of the pump, and turn on the water. This flow of water into the discharge opening will prevent the pump from running dry.

4.Place the Pump Vacuum Tester (P/N 7000030) over the pump suction (inlet) opening (See Figure 18) with the vacuum gauge facing upwards. It may be necessary to apply a small amount of water around the rubber seal of the vacuum tester to make a good suction fit.

5.Check and make sure that there are no air leaks between the vacuum tester and the inlet port on the pump. If air leaks are present reseat vacuum tester.

6.Run the pump for a few minutes while monitoring the vacuum gauge. If the gauge indicates a reading between -25 and -20 in. Hg. (inches of mercury) then it can be assumed that the pump is working correctly.

NOTICE

25 in. Hg (inches of mercury) translates into 25 feet of lift at sea level.

7.If the vacuum tester gauge indicates a reading below -20 in. Hg, it can then be assumed that the pump is not functioning correctly, and corrective action needs to be taken.

8.To test the flapper valve, shutdown the engine. The vacuum tester should remain attached to the pump suction inlet port by vacuum.This indicates the pump's flapper valve is seating properly to hold water in the suction hose when the engine is stopped.This prevents backflow and allows for faster priming when the engine is restarted.
