LiftMaster K15-2002 - Drive Sprocket
The LiftMaster K15-2002 sprocket is a heavy drive component used to transfer power through the operator chain system. Unlike small accessory parts, a sprocket must match the mechanical drive exactly. Tooth count, chain series, bore size, keyway, hub projection, and alignment all affect whether the operator runs smoothly. A worn or incorrect sprocket can damage the chain, bearings, shafts, and motor drive system. This part is listed as a 50B60T sprocket with a 1-1/2 inch bore and is commonly tied to the G152002 reference. It should be selected by the operator parts diagram and original sprocket dimensions, not by appearance alone.
Compatible With
Compatibility should be verified by the operator model, parts diagram, and original part number because LiftMaster mechanical and enclosure parts can vary by operator generation.

Technician Note
Measure the old sprocket and confirm the parts diagram. A sprocket with the right tooth count but the wrong bore, hub, or keyway can cause serious alignment and chain wear problems.
Before Ordering
- Confirm K15-2002 or G152002 in the operator parts list.
- Verify chain series and tooth count.
- Measure bore, keyway, hub width, and overall sprocket position.
- Inspect chain, bearings, shaft, and key stock for wear.
Professional Advisory
Commercial gate drive repairs involve pinch points and heavy moving parts. A qualified gate technician should service sprockets when alignment or shaft wear is in question.
Important Ordering Warnings
- Do not replace a drive sprocket based on tooth count alone; dimensions and alignment must match.
