LiftMaster K94-37694-2 Motor Assembly — SL585101U

The LiftMaster K94-37694-2 is the motor-assembly service reference identified for the SL585101U industrial slide-gate operator. The manufacturer parts table assigns different motor numbers to the half-horsepower, higher-horsepower and three-phase configurations, making the complete operator model essential to selection. Match the installed motor label, electrical arrangement and drive connection before ordering. This is a replacement motor assembly for the documented configuration, not a universal SL585 motor or a capacity upgrade, and it should follow diagnosis of the power supply, brake and mechanical gate load.

Compatibility — Models, Versions and Exclusions

Match the Motor and Diagnose the Complete Drive

Record the full operator model and the label on the installed motor, including its electrical information. Compare the mounting, shaft connection and associated drive components with the applicable repair drawing. A generic horsepower rating is only one selection factor; it does not verify voltage, rotation, mounting or the correct connection arrangement for the equipment being repaired.

Have the technician evaluate the power supply, capacitor where fitted, wiring and mechanical drive before replacing the motor. A motor that hums, overheats or fails to start can be responding to another fault. Check that the gate moves freely and that the gearbox, pulley or other connected components are serviceable. A new motor will not correct a binding gate or damaged transmission.

Specifications and Product Identification

Before Ordering

• Record the entire operator model and installed motor label.
• Match K94-37694-2 in the correct repair-parts table.
• Inspect supply, brake, connections and gate mechanics.
• Confirm current assembly contents and required setup after installation.

Package Contents and Separate Requirements

This listing identifies the replacement motor. A pulley, belt, capacitor, brake, gearbox, wiring harness or complete operator is not promised as included. Confirm the current supplier package against the repair requirements. A parts illustration may show the motor beside these components without including them in the motor carton. Retain only hardware that the service instructions permit to be reused and that the technician finds serviceable.

Safety Warnings — Read Before Installation or Service

• WARNING: Motor service exposes hazardous electrical components and a drive that can move the gate unexpectedly. Use a qualified gate-systems technician and qualified electrical personnel as required.
• Isolate all applicable power and secure the gate before disturbing the drive. Capacitors may retain energy after power is disconnected; follow the manufacturer’s service procedure.
• Do not substitute an unverified voltage, change drive ratios or increase force to overcome binding. Never bypass required entrapment protection.
• Restore guards, verify the prescribed motor and drive operation, and test travel, reversal and all required safety devices before normal use.

Related Products and Important Differences

• LMRRUL monitored photo eye — a separate protection option only where the exact operator and control revision approve it; not a universal legacy retrofit.
• LMWEKITU monitored wireless edge kit — a separate edge communication system for approved controls and resistive edges; not a replacement for this mechanical or electrical service part.

Frequently Asked Questions

Does it fit every SL585 operator?

No. The manufacturer assigns different motors to different configurations.

Is the complete brake included?

No complete brake package is promised; confirm the current motor carton.

Can it increase my gate’s rated capacity?

No. Replacement of a motor does not establish an approved capacity conversion.

Will a new motor fix binding gate hardware?

No. The gate and transmission need independent diagnosis and repair.
