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!
