My work began on the Beogram 4000 turntable that arrived from Germany. As is my practice, the tracking and arm lowering mechanisms were the first to be refurbished. The arm lowering mechanism, controlled by a solenoid and damper arrangement, is pictured here:

After removing components requiring cleaning and lubrication, the area looked like this:

Here are the disassembled parts:

With cleaning and lubrication complete, reassembly followed. Next, I addressed the seized damper-to-arm linkage, accessible only after detaching the sensor arm. The arms are shown from the back:

Two screws at the base of the sensor arm were removed to detach it:

The arm is shown here with the linkage removed. After lubricating the pivot point, I reattached the arm, carefully aligning both arms to be parallel to each other and perpendicular to the carriage rods:

Loose carriage rod bearings were present in this Beogram:

The white component on the rod should be firmly seated in the carriage plate’s underside. Since the second bearing was also loose, I removed both, applied epoxy, and pressed them back into the carriage base:

With the carriage secured, I proceeded to change the tracking sensor’s incandescent bulb with an LED assembly. The original configuration is shown below, the bulb housing is the square at the back:

Removal revealed the sensor aperture:

I installed the LED assembly, replacing the rust-prone sheet metal aperture screw with a durable stainless steel M2 screw and nut. This provides a more secure hold, preventing loosening from vibrations during transport:

The brittle carriage pulley was then replaced with a precision-machined aluminum one, courtesy of Nick. Feel free to reach out if you’d like one for your turntable.

The original pulley is shown here:

And the replacement:

Their aesthetic appeal is undeniable! Truly Beolovely!

While working in this section, I inspected the carriage position switches. Accessing the switch terminals required desoldering the carriage motor leads, removing two screws to lift the board:

After cleaning the contacts with 2000 grit sandpaper, a light coating of DeoxIT D100 was applied to inhibit oxidation. The next task was to begin restoring the keypad cluster.
