3. | Remove side cover. |
4. | Inspect fuel and air line hoses for cracks and/or holes. If fuel line |
| hose is damaged, disconnect from nozzle adapter (see Figure 17, |
| 18, or 19, page 11) and from fuel filter (see page 8). If air line |
| hose is damaged, disconnect from nozzle adapter (see Figure 17, |
| 18, or 19, page 11) and from barb fitting on pump end cover (see |
| Figure 22). |
5. | Install new air and/or fuel line. Attach one end of air line hose |
| to barb fitting on pump end cover (see Figure 22) and the other |
| end to nozzle adapter (see Figure 17, 18, or 19, page 11). At- |
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). |
| For BY35CEH and BY70CEH model heaters, route air and |
| fuel lines approximately as shown in Figure 17, page 11. |
| Note: Hoses are not to be touching photocell bracket. |
| For BY100CEH model heater, route air and fuel lines approxi- |
| mately as shown in Figure 18, page 11. |
| Note: Hoses are not to be touching photocell bracket. |
| For BY150CEH model heater, route air and fuel lines approxi- |
