In stock
The PP204 Rotor Repair Kit is a replacement rotor kit for portable kerosene and diesel-fired heaters. This kit restores proper heater operation by replacing worn rotor and carbon-blade components within the heater assembly.
The rotor is driven directly by the motor and operates with carbon blades inside the pump housing to maintain proper fuel atomization. Over time, rotor blades wear and may reduce heater performance, necessitating routine replacement.

Customer Reviews
The following is service information for the PP204 Rotor Service Kit:
Note: It is important for the service technician to be cautious when working with the PP204 Rotor Service Kit, care should also be taken not to allow any type of oils, kerosene or diesel fuel to come in contact with the rotor or blades.
Broken Rotor or Blades
Disassemble the end cover filter and end pump cover from rear of motor. Visually inspect the rotor and blades to make sure none of the parts are damaged or broken. Make sure that the rotor and blades are free of any type of lubricant.
Never lubricate the rotor or vanes and only clean the rotor or vanes with Brake Clean. The rotor and blades must be clean and dry for proper operation.
Improper Rotor Clearance
Check rotor with feeler gauge for proper clearance (.003-.004) between rotor and pump body. Rotate rotor and make sure all four quadrants of rotor have adequate clearance.
Oversized Rotor
If the fan is hard to turn when the motor end cover is installed, but easy to turn when loosened, the rotor should be removed and lightly sanded. Remove the rotor and lightly sand by placing rotor in the palm of hand and sanding on a flat surface making figure eight rotations. (Use the finest grade of sandpaper available).
Pump End Cover
Always make sure to check the plastic pump end cover for any cracks or damage that would allow air to escape and not be directed to the nozzle. It is very common after time or from over tightening the plastic pump end cover for the cover to develop a crack. This small crack can prevent your heater from starting properly and running properly.
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.
