Pam clocks were used from the 1940s through the 1960s by large companies to advertise all types of products. These clocks advertised everything from soft drinks to motor oil brands. Clock collectors often find value in displaying these old electric clocks, but some Pam clock motors become noisy as they age. Cleaning the clock’s electric motor may make the clock quieter, but if the motor is worn, you must replace it.
Unplug the clock from the power outlet, and place it with its back in an upward position.
Unfasten the screws from the back cover of the clock. Remove the cover to access the synchron motor. Brush out any dust and dirt from around the motor with the sable brush, the type artists often use. Add 2 to 3 drops of clock oil or another metal lubricant to the motor clock gears, if the synchron motor used on the clock has small slits where oil can seep into the small motor metal parts.
Replace the motor and the clock back cover. Connect the clock to the power outlet again to see if the noise lessens.
Disconnect the clock, and remove the back cover again. Remove the motor by unfastening the tiny screws that hold it in place. Use a Phillips precision screwdriver to unfasten these.
Look for the manufacturer name of the clock motor. The name is usually inscribed on the motor casing. In most cases it should be a synchron motor.
Replace the motor with a new one, as these are still made. Replace the cover, and connect the clock to the power outlet.
