Bad wishbone? It's a "yoke" that slides a gear into the fine tuning slug in the tuner. Zenith was famous for bad wishbones. I may have one. The gear teeth get eaten, but some might still mesh.

34-?? WAS the part number, but Zenith went and made it 834- or 800 - something, like the kits. We ordered them in 10's from Bluefield Distributing in the 80s. Our tube caddy had a couple for house calls.

Zeno? - Any recall of the part number??? :yes: He's know for sure.

Replace the belt.

Yes some of them used a small thick belt. There was
also a wish bone & a diaper pin style.
Cant remember the part numbers but we used to go
through lots of 834-?? on the non SGVG sets & other brands.
That was all plastic.
Best to drop the tuner & take a pix of the FT assy.
