Part Number: M22456-1

This item has been replaced with a new part. Please choose the Order Replacement Part option listed below to order the replacement part. #PP204

The M22456-1 Carbon Rotor is the main part of the air pump for your portable kerosene or diesel fired heater.

This M22456-1 Carbon Rotor fits inside the pump ring body on the back of the motor and with the carbon blades and plastic insert makes up the components of the air pump for your portable kerosene heater.

The M22456-1 Carbon Rotor can be purchased as a complete kit which will include the 1 of parts number M22456-1 Carbon Rotor, 4 of part number M8643 1/2 Carbon Blade vane and 1 of part number M22009 Plastic Insert. The can be ordered under part number PP204.

The M22456-1 rotor is driven directly by the motor and is attached to the motor shaft by means of a plastic insert. As the motor rotates, the carbon blades travel outward rubbing against the inside surface of the steel pump body.
The rotor's position inside the pump body is such that it is not concentric with the pump body and a .003/.004 of an inch gap is set at the uppermost quadrant.
As the motor rotates, the air between the blades is compressed and routed to the nozzle through the air line.

The carbon rotor blades will wear out after time and cause the output filter to fill with carbon particles.
Replacement of the output filter and carbon blades should be done on a regular basis.

Service Information

Rotor Replacement Instructions:

WARNING: Never service heater while it is plugged in, operating, or hot.

Severe burns and electrical shock can occur.

1. Unplug heater.

2. Remove upper shell and plastic fan grill from heater.

3. Disconnect the air supply line from the rear metal pump end cover.

4. Remove plastic air filter end cover and air filters. 
Inspect plastic cover for cracks or any damage that would allow air to escape.
 
If the cover is cracker or damaged replace the plastic air filter end cover.

5. Remove metal pump end cover.

Make sure to clean the pump side of the metal pump end cover with some steel wool or similar surface cleaner to allow for clean metal to metal surface contact when the unit is reassembled.

6. Remove the pump ring from the motor by removing the 2 Phillips screws.

Remove the carbon rotor, blades and plastic insert from the motor shaft.

Make sure to clean the pump ring and the back of the motor with some steel wool or similar surface cleaner to allow for a clean metal to metal surface when the unit is reassembled.

It is very important to make sure all metal surfaces have been thoroughly cleaned and prepped for reassemble.

All surfaces are metal to metal contact and must be free from and corrosion, dirt or debris before reassembly.

Do not oil or lubricate the carbon rotor or blades! You may use Brake Cleaner only to clean the rotor, blades and pump housing of any dust or debris before reassembly.

7. Now install new rotor with the plastic insert facing the motor.

Do not use any type of sealant when reassembling the air pump assembly.

8. Install the pump ring body and 2 Phillips head screws.

Adjust the gap between the top of the rotor and the pump ring body to .003 to .004 and tighten pump body.

Turn the motor over by hand to make sure the motor and rotor turn freely.

9. Install the four new carbon rotor blades carefully into the rotor.

 Make sure the blades are in correctly and are the same width as your carbon rotor.

The M22456-2 PP205 and the M22456-3 rotor blades are wider than they are tall and must be installed correctly or the pump will not operate properly.

10. Install metal pump end cover and evenly tighten all 6 screws in a staggered pattern.

Make sure to once again turn the motor over by hand to make sure they are no obstructions and that the rotor has been serviced properly.

11. Install air filters and plastic end cover.

12. Re-connect air supply line.

13. Install plastic fan grill and upper shell.

14. Start unit and adjust pump pressure.

It is not required to have the HA1180 Air Pressure Gauge to set you heater to the proper running pressure, this can be done by increasing the air pump pressure until the nose cone of the heater in a nice glowing orange color and no harsh fumes are being presented by the heater.
