If your motor has a tweaked pulley shaft, feels like it's seized, or has metallic glitter coming from behind the pulleys. The Flange Bearing (Liftmaster PN: 12-19504) on your motor has likely failed. When this bearing fails or gets worn it allows the main pulley shaft to move. Damaging the casing of your motor (K75-19981) and leaving your door inoperable. Leaving you with downtime, and costing you $4,000 to replace your motor.
Our repair kit saves you time and money. Rather than replacing your entire $4,000 motor, or tearing it down to replace the bushing and the casing wall.
