Harman Feed Auger Shaft Assembly, 3-50-00565 Harman

This is the auger shaft assembly that moves the pellets from the hopper to the burnpot. We get a lot of people ordering the wrong shaft so please read this entire description or print off a copy of the PDF links at the bottom to compare against your stove’s serial number to be sure you are getting the correct part.

Your owner’s manual can be confusing because the older part numbers AND the updated part numbers are listed in the most current manuals. Some models had more than one change so there may be up to three (3) different auger shaft assembly part numbers for some models.

New stove and insert models introduced after 2009 all use the 3-50-00565 auger shaft assembly. Models are: 

• Accentra52i
• Accentra52i-TC
• Absolute43
• Absolute43-C
• P35i
• P35i-C
• P43
• P43-C
• Allure50
• Absolute63
• P61-C
• Accentra-Cast-C
• P68-C

Models that existed prior to 2009 phased over to this shaft assembly according to the following serial numbers:

If you have the Advance, Accentra-Cast Freestanding (sometimes referred to as the Accentra 2), or an XXV that precedes the serial numbers above, you are going to have the older style indirect feed system (chain snd sprockets). The auger shaft assembly for your stove was originally part # 3-50-00365. This part number is now obsolete. The new part number is 3-50-00465

If you have the P38, P61, P61A, P68, or the PF100 Pellet Furnace with a serial number that precedes the list above, you are going to have the older style large feeder body system, and the correct auger shaft assembly will be 3-50-00465
