I came into possession of a Pioneer CLD-1030. Not a mind blowing player but I think it looks lovely.

I've hit a bit of a wall though. The mechanism that moves the laser has broken. Not the mechanism itself, as that works, but instead a small plastic piece on the far left side that is supposed to keep the threaded screw (33. Screw Nut assembly) in place. The device was like this from the person I received it from. Here is the Service Manual on Page 13-14 you can see the assembly. Specifically on Page 14, there is a close look.

I tried to Gorilla Glue the piece back on (as I did find it in the case) but it snapped back off while I was trying to reinstall the Screw Nut assembly. What do most others do with this kind of repair? Small plastic non-mechanical pieces that are used to hold other pieces together? Without that piece, the Screw Nut assembly shifts due to the force of the motor causing the Timing Belt (#32 on the schematic) to not have enough tension, thus the laser can't move.

I was thinking of doing the Gorilla Glue method again but letting it rest a whole day before trying to reinstall the Screw Nut assembly, but wanted to check here first.

Yeah... that Nylon Pawl is Exceptionally Fragile. both the CLD-1030, -3030 and CLD-V190 utilize this Mechanism, and perhaps several other 1987/1989 models i am unaware of as well.

i have a 3030; it is my second copy so far. that Pawl indeed Broke on my first one... back when i had first attempted dismantlement for a clean-up and re-lube job over a decade ago.

my second copy, i was far more careful with... and it runs great to this day.

i don't know if that Pawl can be successfully repaired strong enough to bear the strain... but perhaps try GORILLA/Epoxy-gluing some manner of rigid metal plate
to the Backside of the Pawl along it's full length? Perhaps that just may prove sufficient Reinforcement...
