Nakamichi RX202 reversing calibration issues

  • Hey guys,
    I've been having a heck of a time trying to calibrate the reversing mechanism on my nak RX202 deck.
    As mentioned by the helpful folks on Tapeheads, I've set the cassette well into the deck on the "A” side and have set the CAM gear to the far end of the limit. (Clock-wise). Once that is done, I proceeded to calibrate the A side by unplugging the eject wire and shorting CAM B test point to ground.
    Once that is aligned as per manual (and using the corrected method of using VR503 for the A side alignment). I proceeded to short both cam B and cam a wires to ground and made the adjustments to side B.
    The main problem is that once I pull the shorting cables out, the A side tends to continue to attempt to close and you can hear the motor binding. It does not stop. When attempting to reverse to the B side, the mechanism reverses, but before it reaches the end, it immediately goes back to side A and binds the motor.
    Hopefully someone out there can help sort this issue out. Thanks!

    I figured mine out. There are three gears and each has an arrow align all three up. Turn the tape holder so its between A and B with the tray out. The tricky part is keeping the belt on but I managed. Put the belt on the larger gear first and stretch it a little onto the smaller gear as you lower the lid while keep the three arrows aligned. I marked all three arrows with a marker so I can see then better. Then it was very simple to adjust the tray using Cam A and B. Make sure you do the adjustments 2 or 3 times like the manual says.

    There are alignment indicators on the 2 gears. They need to be centered

      Yup, they are centered. But once I pull out the jumper cables for testing, the mechanism motor starts to bind. Believe me, the arrows are perfectly in alignment. 😎

      @@botelhdaI just lifted the table slightly and if you move the gear left and right you'll hear it start to bind - center it - set it down and eject. If it doesn't, adjust slighty, took me about 20 minutes and it works perfect now.
