Yamaha Rotor Cap

Post by disco » Thu Nov 22, 2018 11:27 pm

The kid’s school has a single valve bass, probably a 321 and it’s missing the rotor cap. Anyone know where to get one?

Yamaha’s current bass rotor cap should be compatible. I tried it on a YBL-612, which should have the same rotor cap as the 322.

The rotor should not be touching the the
terminals on the cap, wrong parts? End play on
the distributor shaft? Incorrect install ?
Take it off and have a look inside,

Double check the original horn first. If it's a Yamaha 321, the valve (at least on the 2 that I have) is quite small (and tight). The later 620 and 322 had larger valves.
