This section details the heart of the TD-124. It shows the step pulley arrangement, the intermediate wheel (idler), and the bearing housing.
Unlike modern belt-drive turntables (which are essentially a motor, a belt, and a bearing), the TD124 is a mechanical Swiss watch scaled up to play records. thorens td124 service manual
Old turntables die because of bad oil. The service manual specifies: This section details the heart of the TD-124
Inspect the rubber belt (part CB 908) for cracks or stretching. If the belt makes a "slapping" noise, you can lightly dust it with talcum powder to absorb moisture and improve grip. 2. Critical Lubrication Procedures Old turntables die because of bad oil
Attempting to disassemble or lubricate these components without a guide is a recipe for snapped springs, lost ball bearings, and a turntable that never holds speed again. The is the only map through this mechanical jungle.
The TD-124 is mechanical. It relies on grease and oil. Over 50 years, the factory lubricant turns into a sticky, glue-like substance that slows the platter and strains the motor.
