Figure 1. Firefighting Pump Alignment

WARNING

Removing components by means of wire brushing produces flying particles. These

particles can cause serious injury to personnel. Protective goggles, gloves, and

long sleeves must be worn at all times during wire brushing operations. Failure

to comply can result in serious injury to personnel.

5. Clean the mating faces of the PTO output flange (figure 1, item 8) and the pump input flange (figure 1, item 9)

with a wire brush, and ensure that both surfaces are clean, smooth, and free of corrosion.

6. Verify that the four pump mounting bolts (figure 1, item 10) are tight.

NOTE

The dial indicator fixing stand must be fastened to the pump input flange in order to

obtain an accurate reading. Fastening the fixing stand to the PTO output flange will

result in inaccurate readings.

7. Install the dial indicator fixing stand (figure 2, item 1) on the pump input flange (figure 2, item 2) as shown in

figure 2, to check the angular alignment.
