Liftmaster K15-36001, OUTPUT SPROCKET

Liftmaster K15-36001, OUTPUT SPROCKET

The LiftMaster K15-36001 is the output sprocket used in select LiftMaster residential slide gate operators. It sits in the drive path between the operator output and the gate chain, helping transfer torque so the slide gate moves smoothly and consistently. A worn output sprocket can create chain chatter, uneven travel, chain climbing, rough starts, or visible tooth wear. Since this is part of the main drive system, correct fitment matters for both performance and safety. The strongest compatibility references tie K15-36001 to LiftMaster RSL12V and RSL12VH operators. It should be matched by the original part number and parts diagram instead of being selected by appearance, because other LiftMaster slide operators use output sprockets with different tooth counts, bores, hub styles, or chain sizes.

Technician Note

When an output sprocket is worn, check chain tension, chain condition, idler alignment, shaft wear, and gate rolling resistance. A dragging gate can overload the sprocket and shorten the life of the replacement part.

Before Ordering Checklist

• Confirm the operator model is RSL12V or RSL12VH
• Match the original K15-36001 part number
• Inspect the gate chain and idler hardware
• Check the gate rollers and track for drag
• Verify shaft fit before installation

Professional Advisory

Slide gate drive repairs should be made with the gate secured and power disconnected. If the gate is binding or has damaged safety devices, correct those issues before putting the operator back into service.

Product Questions & Answers

Which models commonly use K15-36001?

K15-36001 is commonly listed for LiftMaster RSL12V and RSL12VH residential slide gate operators.

Is this a limit sprocket?

No. This is an output sprocket for the gate drive system, not a limit switch sprocket.

Can I use it on RSL12UL?

Do not assume so. RSL12U / RSL12UL applications commonly use different output sprocket references.

What are signs the output sprocket is worn?

Hooked teeth, chain jumping, rough gate movement, wobble, and excessive chain noise can point to sprocket wear.

Should I replace the chain at the same time?

If the chain is stretched, rusted, or worn into the sprocket teeth, replacing the chain may be needed to protect the new sprocket.
