If your pellet stove has stopped feeding fuel reliably, a worn or damaged auger shaft is often the culprit. This is the direct OEM-spec replacement shaft for United States Stove 5560 and 5660 series pellet stoves -- designed to restore proper pellet delivery and get your heat source running again.
The auger shaft is the backbone of your pellet stove's fuel delivery system. It connects the auger motor to the auger screw, transmitting torque to move pellets from the hopper into the burn pot at a controlled rate. When this shaft bends, breaks, or wears at the drive end, fuel delivery becomes erratic or stops entirely -- causing flameouts, error codes, or a stove that simply won't stay lit.
United States Stove part 891999 is built to the same specification as the original shaft installed at the factory in the 5560 and 5660 pellet stove models. At 11 inches in length and just 0.2 lbs, it is a direct drop-in replacement that requires no modification.
Engineered specifically for US Stove 5560 and 5660 models. No drilling, cutting, or adapters required.
At 11 inches, this shaft matches the factory dimension needed to properly span the auger assembly in these stove models.
Weighs just 0.2 lbs, consistent with the original steel shaft profile used in this stove family.
Also listed as NBK Parts number 20236, making it easy to verify compatibility when ordering replacement parts.
Pellet stove auger shafts typically fail in one of a few ways. Watch for these signs that a replacement is needed:
Replacing the auger shaft is a common DIY repair for pellet stove owners comfortable working with the internal components. The general process involves disconnecting power, removing the hopper and auger assembly access panel, withdrawing the old shaft, and sliding the new one into position. Reconnect any retaining hardware or cotter pins as applicable to your specific unit configuration.
