Beogram 4002 (5503): Installation of a New Carriage Motor

I recently did a warranty repair on a Beogram 4002 (Type 5503) that I had sold earlier in 2025. It needed a new solenoid switch. My customer decided to also get a new Beolover Carriage Motor for Beogram 4000, 4002, and 4004 installed, while the unit was on the bench.

The new motors make less noise and vibrations. They also run at a lower current than the original motors. This puts less stress on the H-bridge transistors, which have a tendency to fail occasionally.

This shows the original motor still installed:

I unsoldered the two leads and removed it:
This shows it opened up with the new motor next to it for comparison:
The new motor is a bit shorter, i.e. the leads can be conveniently fed through the cutout in the bottom of the enclosure:
This shows it installed:
I tested the unit and as usual the carriage is now running much more quietly. Beolovely!
