A comprehensive service manual for the (Mk I and Mk II) focuses on its unique hybrid belt-idler drive system, requiring meticulous cleaning and lubrication of mechanical parts that may have original lubricants from the 1960s. Core Service Sections Lubrication and Cleaning :
Before splitting the motor casing, use a scratch awl or marker to draw a alignment line across the upper and lower shells. The alignment of these shells dictates the clearance of the rotor.
Cleaning and lubricating oil-retaining bearings and felt pads.
Sintered bronze holds oil within its microscopic pores. To re-oil them, submerge the bearings in genuine Thorens-spec oil (or high-quality turbine oil like Zoom-SPOUT) and heat it gently in a water bath to force the oil deep into the pores.

Reassemble the motor using your alignment marks. Tighten the case screws iteratively in a cross pattern. Spin the pulley by hand; it should spin freely for several seconds. If it feels tight, tap the sides of the motor housing gently with a screwdriver handle to center the self-aligning bronze bushings. 4. Drive System Maintenance

The TD-124 uses an idler wheel to transfer motion from the motor to the platter rim.
The main spindle bearing holds the heavy cast-iron (Mk I) or aluminum (Mk II) inner platter. It must operate under zero friction conditions. Disassembly & Inspection A comprehensive service manual for the (Mk I
The edge must be compliant, perfectly round, and free of flat spots. If the rubber is rock-hard, it must be replaced or sent to a specialist to be re-rubbered.
The E50 uses porous sintered bronze bushings inside felt oil reservoirs. Submerge the end caps in 99% isopropyl alcohol to strip out old, dried oil.
The manual does not show these steps in modern “step‑by‑step” detail (it assumes a factory‑trained technician), but it does include the relevant part numbers and cross‑sections of the bearing housing, which makes it easier to order the correct components.
The TD124 uses a hybrid system where a short rubber belt drives a stepped pulley, which then turns a rubber idler wheel against the inner rim of the flywheel. What is your with mechanical disassembly and soldering
This document—typically 15 to 30 pages depending on the revision—contains:
Unlike belt-drive turntables (like the Linn LP12 or AR-XA) or direct-drive (Technics), the TD124 uses an intermediate that transfers vibration from a stepped motor pulley to the inside rim of the heavy platter. This design offers incredible torque, but it is finicky.
Usually caused by a glazed belt or a dirty idler wheel. The manual details how to clean these surfaces without using harsh chemicals that rot the rubber.
