I have a Pioneer laserdisc player that squeaks quite loudly as it plays.
The sound changes as it plays, getting louder and softer, and
occasionally stops altogether. I don't have the model # right off, but
I'm guessing a belt needs to be replaced or lubed or something?
Definitely no lube!
I have a number of belt-driven devices (telescopes, turntables, drill
presses, etc.) and in the absence of replacement parts have rejuvenated
them simply by cleaning using "Formula 409" which removes any crud and
restores the necessary flexibility and "tackiness" needed in a belt-drive
system; ozone is what "hardens" belts and makes them squeaky in operation.
Given your email address, it appears you're in or near Scottsdale AZ
which is not a friendly place for rubber[ized] parts (e.g., belts or
auto tires (sidewall cracking, etc.)).
I spray a bit of 409 onto a Bounty [brand name] paper towel and rub
the moistened towel over the entirety of the belt until it's clean
and more-pliable and semi-sticky again and I've done that for decades
without any issues or problems. Product info here:
FWIW, it was the US military that popularized the Formula 409 product
circa early 1960s by stocking it in the base/post commissary stores
and I've mentioned here in a.v.l that I've used Formula 409 to clean
LD assemblies many times over the years especially the top and bottom
rubber-like "grip mats" that secure an LD in place in the transport.
Such cleaning prevents slippage when the mats harden over time.
