Ship it to us. We are in Saint Augustine

Lathem mechanical time clocks are widely used in shops, garages, warehouses, and industrial environments throughout South Florida. When one begins to fail, the issue is usually in one of two areas: the motor or the movement. Identifying which component is causing the problem will determine whether you can complete a simple repair yourself or whether professional rebuilding is the better option.

Diagnosing the Problem

Noisy clock that loses time, but printed time matches the clock face:
This typically indicates a failing motor. Most motors begin with a low rumbling sound and eventually develop a high-pitched squeal before stopping entirely.

Clock face shows correct time, but printed time falls behind:
This points to a worn movement. In this case, the movement requires rebuilding or replacement. We commonly rebuild movements for approximately $125 plus shipping, including cleaning and inspection, and return the clock with a service guarantee.

Replacing a Lathem Time Clock Motor (DIY Overview)

Many Lathem motors can be replaced using basic hand tools:

Flat blade screwdriver
#2 Phillips head screwdriver

Motor Replacement Steps

Disconnect power before opening the unit.
Remove the movement by popping off the “C” clip located on the upper left hinge bracket.
Pull the movement assembly out carefully.
Loosen the two Phillips screws securing the clock frame to the case.
Loosen or remove the two screws securing the motor.
Lift the motor out. On older models, gentle prying with a flat blade screwdriver may be necessary.
Disconnect the power leads and rotate the copper “S” spring counterclockwise to remove it.

Install the new motor in reverse order and reconnect wiring before reassembly.

Cleaning and Maintenance While Open

While servicing the unit, you may:

Lightly lubricate appropriate movement components.
Remove lint and ink buildup from print wheels using a small wire brush.
Clean internal debris carefully.

Avoid over-lubrication or soaking sensitive components. Use cleaning agents sparingly and ensure parts are completely dry before reassembly.

Professional Repair Option

If the movement requires rebuilding, professional service is often more cost-effective than replacing individual internal components. For customers in Miami and throughout Florida, clocks can be shipped for rebuilding, cleaning, and inspection. Rebuilt movements are returned tested and guaranteed.
