LiftMaster 041ASWG-0011SA Shaft Assembly for SWG300 Swing Gate Operators
The LiftMaster 041ASWG-0011SA shaft assembly is a mechanical drive component used in the SWG300 swing gate operator family. In a swing gate actuator, the shaft assembly is part of the system that transfers motor and gearbox force to the gate arm. When the shaft is worn or damaged, the gate may move unevenly, produce extra play at the arm, bind during travel, or place added load on the motor and gearbox.
This part should be treated as an SWG300-specific service component. Similar LiftMaster swing gate operators may use different shafts, release parts, brackets, and arm assemblies, so matching by operator model and parts diagram is important.

Technician Note
Before replacing the shaft, check gate hinge condition, arm geometry, bracket position, and operator mounting. Excessive gate drag or a misaligned arm can damage a new shaft assembly.
Before Ordering Checklist
- Confirm the operator is an SWG300 series unit.
- Match the original shaft assembly to 041ASWG-0011SA.
- Inspect gate hinges, brackets, and arm pivot points.
- Check for bent arms or mounting post movement.
- Do not substitute LA400 or LA412 shaft parts unless confirmed by the parts diagram.
Professional Advisory
Swing gate mechanical repairs should not be made while the gate is under load or moving. Secure the gate, disconnect power, and use a qualified technician if the gate is heavy, misaligned, or unsafe.
Product Questions & Answers
What operator is 041ASWG-0011SA for?
It is commonly associated with LiftMaster SWG300 swing gate operator shaft assembly service.
Is this the same as an LA400 shaft assembly?
No. LA400 uses different shaft service parts, such as 041ASWG-0111SA for select LA400 applications.
What symptoms can indicate shaft wear?
Symptoms may include loose arm movement, uneven travel, binding, clunking, or visible shaft damage.
Should hinge condition be checked?
Yes. Worn or binding gate hinges can overload the shaft assembly and other drive components.
Can I order this by appearance?
No. Use the operator model, original part number, and parts diagram because similar swing operator parts are not always interchangeable.
