LiftMaster K75-50214 Swivel Arm Q198
The LiftMaster K75-50214 swivel arm is a replacement arm component used in select LiftMaster gate operator linkage assemblies. A swivel arm allows controlled pivoting movement between connected mechanical parts, helping the operator transfer motion without binding through the gate travel. When the swivel arm is bent, badly worn, loose at the pivot, or seized from corrosion, the gate may jerk, drag, stop short, or place extra stress on the gearbox, bracket, or control limits. Available documentation lists this as a LiftMaster service part for various residential and commercial gate operators, but not as a universal arm. Matching the original Q198 reference, arm length, pivot style, and hardware is important before ordering.
This part is best suited for service work where the operator has already been identified and the original part location is known. On older LiftMaster and Elite gate operators, small differences in production date, UL listing generation, enclosure style, arm geometry, or mounting hardware can change which replacement part is correct. For that reason, this product page uses careful compatibility language and includes the common related numbers customers may use when searching for the part.

Technician Note
When replacing this part, inspect the surrounding brackets, fasteners, bushings, pivots, wiring, covers, seals, and drive hardware in the same assembly. A failed support part can sometimes be caused by a misaligned gate, loose mounting hardware, worn clutch parts, or a cabinet that has been exposed to water or debris. Replacing only the visible damaged part without correcting the cause can lead to repeat failures.
Before Ordering
- Confirm the LiftMaster model number on the operator nameplate.
- Compare the original part number and Q-number with the parts diagram.
- Check mounting holes, linkage shape, cover style, hardware length, or electrical/mechanical configuration as applicable.
- Inspect related worn hardware before replacing only one part.
- For commercial gates, restore all covers and safety equipment before returning the operator to service.
Professional Advisory
Commercial gate operators can move heavy gates and may contain high-voltage wiring, stored mechanical force, or pinch points. Mechanical service should be performed with the gate secured and the operator power disconnected by a qualified technician when needed. Do not bypass monitored safety devices or operate a damaged gate system without proper safety protection.
Important Ordering Warnings
Do not substitute this swivel arm based only on appearance. Arm length, pivot spacing, and hardware style can vary by operator model.
