LiftMaster K13-10465 Shaft Collar, 1 Inch ID
The LiftMaster K13-10465 is a 1 inch inside-diameter shaft collar used to hold a shaft-mounted component in the correct position inside select gate and commercial door operator assemblies. In a commercial operator, a collar like this may help maintain spacing on a shaft, retain a sprocket or bearing position, or keep an assembly from drifting during cycling. It is a small mechanical part, but incorrect collar size or location can create alignment problems, chain tracking issues, or excess side load on nearby bearings. Because LiftMaster uses different collar sizes across many operator families, K13-10465 should be matched by part number and inside diameter, not just by visual appearance. If the original collar is missing or damaged, review the parts diagram to confirm the correct shaft location and any related key, set screw, spacer, sprocket, or bearing parts needed for the repair.

Technician Note
If a collar has moved on the shaft, look for the cause before replacing it. A loose set screw, worn shaft, damaged keyway, misaligned sprocket, or binding driven component can let the collar walk out of position.
Before Ordering Checklist
- Measure the existing shaft and confirm a 1 inch inside diameter is required.
- Verify K13-10465 or 13-10465 appears in the operator parts diagram.
- Check whether any set screw, key, spacer, or adjacent bearing is also damaged.
- Compare the collar location before removing the old part.
- Do not substitute a generic collar if the OEM part is required for spacing or shaft retention.
Professional Advisory
Mechanical shaft and collar repairs should be handled with the operator disabled and the door or gate secured. If the collar is part of a loaded drive assembly, use a qualified gate or commercial door technician.
Product Questions & Answers
What size is the K13-10465 shaft collar?
K13-10465 is listed as a 1 inch inside-diameter shaft collar.
Is this only for one LiftMaster model?
No. It is used across select LiftMaster gate and commercial door operator assemblies, but the exact application depends on the parts diagram.
Can I use any 1 inch shaft collar instead?
A generic 1 inch collar may not match the OEM width, set-screw style, or spacing requirement. Use the OEM part when the diagram calls for K13-10465.
What causes a shaft collar to loosen?
Common causes include a loose set screw, worn shaft surface, vibration, missing key hardware, misalignment, or excessive side load from a worn sprocket or bearing.
What should I check before installing it?
Confirm shaft diameter, part number, collar position, set-screw condition, and the condition of nearby sprockets, keys, spacers, and bearings.
