After a thorough cleaning, the changer was re-assembled.A new idler wheel was installed since the rubber
on the old one had hardened and would no longer transfer rotation from the motor to the rim of the platter.
The new rubber idler assures that the speed will be correct and constant, and the the torque from the motor
is adequate to move all the gears and levers correctly through the change cycle. Finally a new cartridge was
installed in the tonearm, replacing the original that no longer worked.
