Liftmaster K09-50124, CHASSIS, Q067
The LiftMaster K09-50124 Q067 chassis is a structural replacement part for compatible HCT Series overhead gate operators. The chassis acts as the mounting backbone for the operator, keeping the drive assembly, cover hardware, and related mechanical components positioned correctly. A damaged chassis can create more than a cosmetic issue; it can affect gear alignment, cover fit, chain or trolley tracking, and the way stress moves through the operator frame. This part is commonly associated with LiftMaster HCT overhead gate operators, Hercules/HCT5011 references, and service parts where Q067 is listed. Because the chassis is central to the operator assembly, it should be matched carefully by parts diagram and should be installed with attention to alignment. If the original chassis was damaged by impact or gate bind, the gate, track, rollers, and drive hardware should also be inspected.
Compatible With
- LiftMaster HCT Series overhead gate operators
- LiftMaster / Elite Hercules overhead gate operator references
- HCT5011-style overhead gate operator applications where Q067 is listed
- Select overhead gate operators using chassis K09-50124 / Q067
Compatibility should be verified by the original part number, operator model, and LiftMaster parts diagram. Similar-looking gate and access-control parts may not be interchangeable across model generations.

Technician Note
Before replacing this part, inspect the surrounding hardware and the reason the original part failed. Bent brackets, worn bushings, loose fasteners, water intrusion, damaged covers, gate bind, or incorrect previous repairs can cause repeat failures even after the correct replacement part is installed.
Before Ordering
- Confirm the manufacturer part number on the original part or parts diagram.
- Verify the exact operator, keypad, telephone entry, or access-control model.
- Compare mounting points, cover shape, length, handedness, and related hardware where applicable.
- Check whether companion parts are damaged or missing.
- Do not bypass required safety devices or modify factory safety-related assemblies.
Professional Advisory
Gate and commercial operator parts can involve heavy moving assemblies, stored mechanical force, and high-voltage wiring. If the system has unsafe movement, missing safety devices, damaged wiring, or alignment problems, have the equipment inspected by a qualified gate or commercial door technician before returning it to service.
Product Questions & Answers
What operators is K09-50124 commonly used with?
K09-50124 / Q067 is commonly associated with LiftMaster HCT Series overhead gate operators and Hercules/HCT5011-style parts references.
What does the chassis do in an overhead gate operator?
The chassis supports and aligns major operator components, helping the drive, gearbox, covers, and related hardware stay properly positioned.
When should a chassis be replaced?
Replacement may be needed if the chassis is bent, cracked, badly corroded, impact damaged, or causing alignment problems.
Is K09-50124 the same as a gearbox cover?
No. K09-50124 is the chassis. Gearbox covers, arm brackets, and track kits are separate HCT-related parts.
What else should be checked during chassis replacement?
Inspect track alignment, gate travel, gearbox parts, covers, mounting hardware, and any damage that may have caused the chassis failure.
