The LiftMaster 15-10717 dual sprocket is a commercial door operator mechanical service part for select LiftMaster jackshaft commercial door operators using the 48B10/41A24 sprocket shown in the parts diagram. This part is used in the chain and clutch drive system and should be selected by the operator parts diagram, not by appearance alone.
Commercial jackshaft and hoist-style operators can use similar-looking shafts, sprockets, disconnect plates, and linkage parts that are not interchangeable. Before ordering, confirm the exact operator model, diagram item number, part number, and any orientation or horsepower notes shown for the installed unit.
This dual sprocket services the mechanical area of the operator where motion, clutching, hoist operation, or disconnect movement is transferred through the drive assembly. A worn or incorrect part can cause noise, slipping, poor engagement, binding, rough travel, manual disconnect trouble, or repeat hardware damage.
The LiftMaster 15-10717 is commonly associated with select LiftMaster jackshaft commercial door operators using the 48B10/41A24 sprocket shown in the parts diagram. Use cautious fitment practices because model generation, horsepower, option package, and diagram revision can affect the correct repair part.
Do not use this part on operators using a different chain size, tooth count, bore, shaft, or sprocket stack. A part that looks close can still have the wrong length, bore, tooth count, hole pattern, hand orientation, shaft location, or linkage geometry.

When replacing LiftMaster 15-10717, compare the failed part to the service diagram and the installed operator before removing more hardware than needed. On commercial doors, a worn shaft or disconnect part is often a symptom of another issue such as poor door balance, chain misalignment, worn bearings, damaged sprockets, or clutch over-tightening.
Commercial door operator mechanical repairs should be performed with the door secured, power disconnected according to site safety procedures, and stored-energy hazards understood. Do not adjust springs, hoist assemblies, or high-load door hardware unless qualified to do so. After installation, test the door and operator carefully with all required safety devices and manual release functions working properly.
If the operator has damaged shafts, stripped sprockets, bent disconnect parts, repeated clutch slipping, or poor manual operation, the full door system should be inspected by a qualified commercial door technician. Do not return a commercial door operator to service if the door is binding, out of balance, unsafe, or missing required safety equipment.
15-10717 may be correct only if your operator parts diagram calls for 15-10717 or a confirmed related number. Verify the exact operator model, operator family, shaft or disconnect location, and service diagram before ordering.
No. Do not assume 15-10717 will fit another LiftMaster commercial operator family. Similar mechanical parts may use different shafts, sprockets, plates, hand orientation, bearings, or linkage geometry.
Inspect related drive or disconnect parts for wear, looseness, damage, missing hardware, poor alignment, and door balance problems. Replacing one worn part without checking the surrounding assembly can lead to repeat failure.
Package contents can vary by supplier and kit type. Treat 15-10717 as the listed dual sprocket only unless the current listing or parts breakdown confirms additional hardware, shafts, plates, sprockets, springs, or fasteners.
This is a commercial door operator mechanical part. The door, chain, spring system, hoist, and operator can create serious pinch, drop, and stored-energy hazards. Use a qualified commercial door technician if the repair is not clearly understood.
LiftMaster commercial operators have multiple model families and generations. The correct part depends on the exact diagram location, operator family, horsepower range when applicable, hand orientation when applicable, and related hardware in the assembly.
