Description
The LiftMaster K17-50095 Gear Pulley is a replacement drive pulley for compatible LiftMaster gate operator drive assemblies, featuring a 2-1/2" outer diameter and a 5/8" bore.
In practical terms, this gear pulley transfers rotational motion from the operator motor to the belt-driven drive train, maintaining proper belt alignment and torque transfer. It’s a common wear item in service and preventive maintenance when the original pulley shows signs of wear, grooves, or misalignment that can cause belt slipping or uneven movement. Replacing the pulley helps restore reliable gate operation in both commercial and residential access control installations.
Compatibility: Designed for use with LiftMaster gate operators and drive systems that require a 2-1/2" OD pulley with a 5/8" bore. Use as part of standard maintenance for LiftMaster gate operator installations.
