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 25, page 13).

Note: Rotate rotor one full turn to ensure 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 10).

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

 

tach one end of fuel line hose to fuel filter (see page 8) and the

 

other end to nozzle adapter (see Figure 17, 18, or 19, page 11).
