Welcome Back to Pellet Tech 101!
In today’s video we cover removal and replacement of the Harman auger feed motor. This video will go through replacement of the direct drive Harman auger motor. Depending on the year and model Harman you have some will have a direct drive feed system and some will have a chain driven feed system. If you have a Harman with a chain drive feed system, click here.
The Harman line of pellet, corn and coal stoves have a unique feed system to other manufacturers and models. Understanding how the Harman feed system works and how to replace the auger motor yourself can save you time and money.
The majority of auger motors including Harman auger motors are sealed bearing and do not require lubrication. We do recommend periodic inspection at least once per season to clean off any dust, hair or debris that has accumulated on or around the auger motor. Generally when the auger motor needs to be replaced it will let you know; noisy, inconsistent feed, or no fuel feed at all.

Hey guys,
On replacing the (XXV) direct drive feeder motor, no space to reach the drive shaft lock nut. Is there a way to remove thee back panel? All I see is rivets. Thanks in advance, Vern
Hey Vern, thanks for the message. I believe you are referring to the upper back panel which is fully riveted. The Side/Lower back panels which slide out once loosing the 5/16″ screws on each side, do allow access to remove the direct drive feed motor in the XXV. We should have just three bolts to remove to pull out the feed motor – the 2- 5/16″ bolts securing the bracket to the motor, and the 7/16″ set bolt that secures the auger shaft to the feed motor. By Drive Shaft Lock Nut, I believe you are referring the the set bolt correct? A Deep-well 7/16″ socket should be able to sneak in there to loosen it up and pull the motor off.
