LiftMaster Q014 / K15-41B26LGH Drive Sprocket — Legacy SL3000 Omni
LiftMaster Q014 / K15-41B26LGH Drive Sprocket — Legacy SL3000 Omni
The LiftMaster Q014 supplier SKU identifies K15-41B26LGH, the drive sprocket shown in the manufacturer’s legacy SL3000 and SL3000ULE Omni parts breakdown. It belongs to the gate’s mechanical drive and must match the installed shaft, chain arrangement and operator generation. It is a different service component from the smaller limit-switch sprocket used to track travel. Match the full part number before ordering; the SL3000 name alone does not establish compatibility across every later operator revision.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| SL3000 / SL3000ULE Omni | Use the applicable legacy parts breakdown and confirm the installed sprocket. |
| Later SL3000U / SL3000UL | Check the model-specific drawing; this listing does not establish blanket interchangeability. |
| Q016 limit-switch sprocket | Different drive position and service reference; not a substitute for Q014. |
| CSL24-series output sprockets | Different platform; a shared chain family does not establish shaft or hub fit. |
| Replacement chain and master links | Match chain size, condition and required length separately from the sprocket order. |
Inspect the Chain and Shaft Along with the Sprocket
Hooked or damaged teeth can be only one part of a worn drive. Have the technician inspect the chain, shaft fit, retention hardware and alignment before deciding what to replace. A new sprocket running with unsuitable or heavily worn chain can leave the original problem unresolved. The gate must also move freely through its intended travel.
The drive sprocket and the limit-switch sprocket perform different jobs even though both are visible in the same operator. Identify the exact location of the damaged part in the exploded drawing. Do not select a replacement only by counting teeth or matching an online photograph; the hub, shaft engagement and retention method also have to agree with the documented assembly.

Before Ordering
- Record the full operator model and confirm the Omni-generation diagram.
- Match Q014 to K15-41B26LGH on the service reference.
- Inspect the chain path, shaft and retaining components.
- Determine whether chain, master links or additional drive hardware also need replacement.
Package Contents and Separate Requirements
This listing identifies the drive sprocket. Chain, master links, gear reducer, limit-switch mechanism and a complete shaft assembly are separate requirements unless expressly included in the current supplier package. Confirm any key or retaining hardware supplied with the sprocket. Do not interpret neighboring parts in the exploded diagram as items automatically shipped in this order.
Safety Warnings — Read Before Installation or Service
- WARNING: A moving gate and exposed chain and sprockets can cause serious injury. Installation and service require a qualified gate-systems technician.
- Isolate AC power, batteries and any solar supply as applicable, and secure the gate against unexpected movement before work begins.
- Keep people clear of the gate and drive during supervised testing. Never bypass required entrapment-protection devices or increase force to overcome a mechanical fault.
- Restore all covers and guards, then verify travel endpoints, reversal and every required safety device before returning the gate to normal operation.
Related Products and Important Differences
- #41 roller chain, 10-foot length — compare the chain specification and required length for the complete drive; not included with this service part.
- #41 master link — a separate joining component for the matching chain; it does not establish sprocket or shaft fit.
Frequently Asked Questions
Is this the limit-switch sprocket?
No. The legacy diagram identifies Q016 / K15-35B17LGF separately for that function.
Will any sprocket for the same chain fit?
No. Shaft engagement, hub geometry, alignment and the specified service reference must also match.
Should the chain be inspected at the same time?
Yes. Diagnose the complete drive so worn chain or a damaged shaft does not undermine the repair.
Can I use the SL3000 name alone to choose it?
No. Identify the generation and verify the exact part in the applicable service drawing.
