This is the auger shaft assembly that moves the pellets from the hopper to the burnpot.

Some stove and inserts models were never updated to the UL feeder body because they were obsolete by 2009. Other models were discontinued at that time. These models all use the 3-50-00465 auger shaft assembly, they include:

  • P61 uses 3-50-00465 (no automatic ignition) became the P61A which used both assemblies, see serial pre/post serial for P61A

Auger shaft assembly, part # 3-50-00465 is also used for ALL indirect, 'chain driven' feed systems for the XXV, Accentra-Cast (also called Accentra 2 in some manuals)and, the Advance.

  • The original part # for all indirect feed systems (chain and sprocket) was part # 3-50-00365. This part # was updated in 2009 to part # 3-50-00465 to reflect the change to the re-designed direct drive UL feeder bodies.

Instructions

Assembly Instructions For Harman Feed Auger Shaft Assembly, 3-50-00465

To replace the feed auger shaft:

  1. Unplug your stove
  2. If there are pellets in the hopper
  3. Gain access to the rear of the stove
  4. If your stove has a chain driven feed system, the chain will need to be removed by loosening the white tensioner block from under the chain to create slack and removing the left-side sprocket from the feed motor by loosening the 1/8" allan key screw in the hub of the drive sprocket
  5. If you have direct drive (motor attached directly to the auger shaft), locate the 7/16" motor set screw on the roller cam assembly and loosen it. Disconnect the wires from the motor to the wiring harness and pull on the auger motor. The motor will uninstall with the mounting frame attached to the motor, set this aside.
  6. Open the the fines collection box access door and remove
  7. Lift on the feed plate pusher arm to extend the feed plate out of the feeder body weldment. Remove the feed plate. Sometimes the crossover hose may restrict the full motion of the pusher arm. If so, gently push the hose out of the way so that the pusher arm can be rotated up and fully to the left
  8. Locate the two 1/2" hex screws on the mounting ring that hold the auger shaft in to the feeder weldment. remove these two screws, then remove the mounting ring. Note: different models have different way in which these mounting screws fasten to the weldment. If nuts or threaded couplers are used, locate them and set them, aside, they will be needed to secure the mounting ring again.
  9. Pull the auger shaft from the feeder body. If the auger shaft is difficult to pull out, the shaft can be freed by striking the auger itself with a wooden dowel from inside the the firebox. This will break the seal and allow the auger to come out.
  10. Install your auger shaft. Secure the mounting ring back into the stove and tighten the two hex screws to a uniformed torque (equal tightness)
  11. Reinstall the feed plate and drop the pusher arm down
  12. Reinstall the cam set screw assembly on the auger shaft, with secondary sprocket attached if your stove has a chain drive assembly
  13. Reinstall the auger motor or sprocket assembly and connect to the auger shaft with the 7/16" set screw
  14. Reinstall the drive sprocket and chain if you have a chain drive system and adjust the chain tensioner


Troubleshooting

Why would you need to replace your auger shaft? Typically, this is not a part that is replaced and it should last the life of your stove. That said, there are a few scenarios where the shaft will require replacement.

  • Flighting on shaft is broken at the front weld or tip
  • Auger is worn down
  • Feed system had a jam that damaged the auger
  • Feeder body is being replaced


Some stove models that used the '00675' burn pots made in 2006-2008 may have a "5-hole" burnpot. Harman made a change to the burnpot design in these two stove models. This change caused some problems that were not evident for many years later. The faulty burn pots will have 5 holes at the base of the slope, directly in front of the opening for the feed tube in front of the auger. These holes allowed the fire to burn too low and too hot in the burn pot resulting in the auger shaft actually melting away at the tip.
