Pump Rotor

(Procedure if rotor is binding)

1.Remove upper shell (see page 10).

2.Remove filter end cover screws using 5/16" nut- driver.

3.Remove filter end cover and air filters.

4.Remove pump plate screws using 5/16" nut- driver.

5.Remove pump plate.

6.Remove rotor, insert, and blades.

7.Check for debris in pump. If debris is found, blow out with compressed air.

8.Install insert and rotor.

9.Check gap on rotor. Adjust to .076/.101 mm (.003"/.004") if needed (see Figure 27).

Note: Rotate rotor one

full turn to insure the gap is

.076/.101 mm (.003"/.004") at tightest position. Adjust if needed.

10.Install blades, pump plate, air filters, and filter end cover.

11.Replace fan guard and upper shell.

12.Adjust pump pressure (see page 14).

Note: If rotor is still binding, proceed as follows.

13.Perform steps 1 thru 6 above.

14.Place fine grade sandpaper (600 grit) on flat surface. Sand rotor lightly in “figure 8” motion four times (see Figure 28).

15.Reinstall insert and rotor.

16.Perform steps 10 thru 12 above.
