The LiftMaster K-SPSHORT is a roll pin (spring pin) used to secure components such as sprockets, gears, and pulleys to a shaft in LiftMaster operator assemblies. Specified at 1/4" x 1-1/2" and supplied in a pack of 10, this LiftMaster replacement part helps lock rotating components in place to transmit torque and prevent slippage in gate and door operator drive trains. It’s suitable for maintenance, repair, or rebuild work where the original fastener is worn, missing, or damaged, helping restore reliable operation in residential and commercial applications.
This roll pin is intended for assemblies that call for part number K-SPSHORT, commonly found at output shafts, idler sprockets, and drive gears across various LiftMaster gate and door operators. Installation involves aligning the cross-holes of the shaft and mating component, then driving the pin in with a roll-pin punch and hammer until properly seated. Always disconnect and lock out power before service, wear eye protection, and follow the model-specific LiftMaster manual or parts diagram to verify compatibility and orientation. No programming or electrical setup is required after replacement.
