LiftMaster K41-0085-000 Clutch Assembly for HDSW24UL
The LiftMaster K41-0085-000 clutch assembly is a mechanical service component for the HDSW24UL heavy-duty swing gate operator. This operator is designed for large commercial swing gate applications, so the clutch/linkage area must handle high torque while protecting the drive system from abnormal force and mechanical stress. A worn or damaged clutch assembly can contribute to slipping, rough movement, poor torque transfer, or unusual mechanical noise. Because some supplier descriptions use the spelling "cludge assembly," the safest way to identify this part is by the K41-0085-000 part number and the HDSW24UL parts diagram rather than the wording alone.

Technician Note
Do not use this part to compensate for a dragging gate or incorrect arm geometry. Mechanical binding should be corrected before a replacement clutch assembly is installed.
Before Ordering Checklist
- Confirm the operator is HDSW24UL.
- Match the original part number to K41-0085-000.
- Inspect output shaft, arm hardware, gearbox, and gate hinges for mechanical drag.
- Do not substitute CSW, LA400, LA500, or other swing operator clutch parts.
- Service the operator with power and battery power disconnected.
Professional Advisory
Heavy-duty gate operator repairs should be performed by a qualified gate technician when electrical power, battery wiring, high-load gate movement, or safety-device circuits are involved. Do not bypass monitored entrapment protection devices to make an operator run.
Product Questions & Answers
Why do some listings call this a cludge assembly?
Some supplier listings use the wording cludge assembly, but it is commonly treated as the HDSW24UL clutch/linkage service assembly.
Does K41-0085-000 fit HDSL24UL slide operators?
No strong compatibility references were found for HDSL24UL. It is written for HDSW24UL swing gate applications.
What symptoms can point to clutch assembly wear?
Slipping, rough torque transfer, abnormal mechanical noise, or damaged clutch/linkage hardware can point to this area.
Can this fix a gate that is hard to swing by hand?
Not by itself. A hard-moving gate may have hinge, geometry, or gate-frame problems that must be corrected first.
Is this interchangeable with CSW24U clutch parts?
No. HDSW24UL heavy-duty parts should not be substituted with CSW-series parts by appearance.
