Starting with the slide in deck . It`s similar to working on a walkman. Tight tolerances . Three of the gears are cracked in the same areas , 3 cracks in each. To get to the belt underneath ( the shorter one , not the broken one) it was necessary to remove 2 of the cracked gears. After removing the plastic retaining circlip on the top, one gear came apart, in 3 pieces . Carefully placed on a piece of scotch tape folded underneath to stick both to the table and the gear , epoxied and using the adhesion of the tape, was able to glue the gear back together. The gear removes easily from the tape .
The main deck , need to unsolder the ground to the motor, and 3 from the limit switches , remove (3?) plugs from the upper board, and 2 from the amplifier board, the one that is flipped on it`s side with the large aluminum heatsink . This was necessary yo completely remove the deck. Having removed the deck completely from the chassis, belts melted and huge mess. Cleaned most by hand, then installed new belts , using 99 Isopropyl alcohol qtips, connecting motor to external dc power so all pulleys engaged, held the qtip in the grooves of the pulleys until clean. Reassembled, pause would engage when pressed without play button on . When pressing play, pause could not be used.Turns out the nylon flap that handles pause was worn out and would not engage. A bit disappointing but not a huge loss. Not easy to source one as these boxes are fairly rare.
Functionality follow up in next day or 2.
