LiftMaster K07-3611 Disconnect Bushing Overview
The LiftMaster K07-3611 is a disconnect bushing replacement part for select SL590 slide gate operator applications. In the manual disconnect system, the bushing helps support and guide the release linkage so the operator can be disengaged from the gate drive when manual operation is needed. A worn or damaged bushing can make the disconnect feel sloppy, hard to operate, or inconsistent.
Available compatibility references point specifically to LiftMaster SL590 slide gate operators. Because SL590 operators can vary by age and configuration, and because manual disconnect hardware can include several similar-looking pieces, the installed parts diagram should be checked before ordering. This part should not be assumed to fit SL3000, SL595, SL585, SL575, or other slide operators unless their own parts documentation calls for K07-3611 or a listed related number.

Technician Note
A stiff manual disconnect may come from a worn bushing, but it can also come from bent linkage, corrosion, poor lubrication, or a gate that is binding on the track.
Before Ordering
- Confirm the operator is an SL590 or diagram-supported model
- Match the original part to K07-3611, 07-3611, 073611, or G073611
- Inspect the entire disconnect linkage for bent or seized parts
- Check that the slide gate rolls freely when disconnected
- Secure power before servicing the operator cabinet or drive assembly
Professional Advisory
A manual disconnect must work reliably for service and emergency access. Do not disable or bypass the disconnect mechanism to keep an operator running.
