Tuner Clean & Lube!
The 655 has a friction drive from the main tuner knob to the "hoop", and a sprung-ball clutch drive thing for the fine tuning knob. Mine was pretty stiff, and the whole tuner was somewhat filthy. Parts were disassembled, cleaned, lubed and reassembled. Here's the result- smooth! Now waiting on new rubber mounts from Renovated Radios...

Hoop is trapped between a sprung plate and the bearing body- arrow:
Pull the shaft/bearing/bracket off:
Pull the shaft unit apart and clean the old grease out of everything. When reassembling, the balls ride on the arced part of shaft on right:
Reassembled shaft unit:
Tuner itself was cleaned with soapy water and a toothbrush. No need for dishwashers or ultrasonics:
