Liftmaster K15-41B26LGH replacement Drive Sprocket SL3000 Commercial Slide Gate
The LiftMaster K15-41B26LGH drive sprocket is a replacement sprocket used on select LiftMaster / Elite SL3000 commercial slide gate operators. It is commonly referenced by the related number Q014. The sprocket is part of the drive system that engages the chain and transfers motor output into gate movement.
Drive sprockets wear over time as the chain cycles across the teeth. When the teeth become hooked, rounded, chipped, or misaligned, the chain may skip, ride unevenly, or make noise during operation. Replacing a worn sprocket can help restore smoother drive engagement when the chain and related hardware are still serviceable.
This part is specifically associated with SL3000 slide gate operator systems. It should not be treated as a universal LiftMaster sprocket because tooth count, bore, shaft style, and chain size must match the operator. Always compare the existing sprocket and parts diagram.

Technician Note
A new sprocket should not be installed on a badly worn or misaligned chain. Check the chain, idlers, drive shaft, key, set screw, and gate rolling condition so the replacement sprocket is not damaged prematurely.
Before Ordering
- Confirm the operator model is SL3000
- Match K15-41B26LGH or Q014 in the parts diagram
- Compare tooth count and bore/shaft fit
- Inspect chain wear and tension
- Check gate track and rollers for binding before final adjustment
Professional Advisory
Drive sprocket replacement involves moving gate hardware and chain tension. Secure the gate and disconnect operator power before service.
Important Ordering Warning
Using the wrong sprocket can cause chain misalignment, premature wear, or loss of drive engagement.
Product Q&A
What operator does K15-41B26LGH fit?
It is commonly listed for LiftMaster / Elite SL3000 commercial slide gate operators.
What is Q014?
Q014 is a related part number commonly associated with the K15-41B26LGH SL3000 drive sprocket.
What are signs of a worn drive sprocket?
Look for hooked or rounded teeth, chain skipping, grinding noise, uneven travel, or a chain that will not stay properly engaged.
Should I replace the chain too?
If the chain is stretched, rusted, kinked, or does not seat correctly on the new sprocket, it should be replaced or serviced.
Can this sprocket fit other LiftMaster slide operators?
Do not assume so. Confirm by parts diagram, tooth count, bore, shaft style, and chain size before using it on any operator other than the listed SL3000 application.
