Harman 3 1/2" Free Standing Sprocket Hub

This is part of the old style chain and sprocket feed system for the Harman Pellet stoves listed below

Fits the XXV, Accentra Free Standing & Advance, 1-10-08550W. We carry a huge selection of brand name stove parts.

Note: When Harman first distributed their stoves with the chain/sprocket feed system, they had one 2-1/2" sprocket and one 3-1/2" sprocket. The chain used for that version is shorter than the next version. The 2-1/2" sprocket is now a 3-1/2" and the chain is longer. If you have a Harman pellet stove with a 2-1/2" sprocket that needs to be replaced, you will need to use the 3-1/2" version and replace the chain to the longer one.

Helpful Tips

This part mounts to the auger feed motor. Early versions of this sprocket use to be smaller in diameter (reduction gear). If you are replacing a hub sprocket that is smaller than 3 1/2", you need to install the updated 1:1 sprocket kit. Small hub sprocket setups will not accommodate the newer 3 1/2" sprocket.


Unfortunately sometimes products do not work like they are supposed to. We offer a 6 month warranty on manufacturer defects. Some manufacturers make this a very simple and easy process unfortunately others do not. Please be advised that warranty claims for these parts may take up to 4 weeks for processing, and customers must cover shipping.
