Fixing high wow&flutter on a Technics SL-BD22 Turntable

- I picked up a free Technics SL-BD22D Turntable. A typical machine from the late 90s, this Technics is a simple but still very decent record player for its time. After a quick fix and getting a new belt, it worked fine, but its wow&flutter was higher than expected.
In this video, I investigate what keeps this turntable from working perfectly and fix it, so that I can give it to a new owner.

It was a mad decent plate to listen records, not made to scratch. Namastè.
I really hope it wasn't used for scratching.. would explain some stuff though.
back in a time, when servive manuals were standard.
So very true!
That is an excellent video thx for posting 👍
Great video! What kind of grease do you use on plastic parts?
Proper grease for plastic is surprisingly hard to come by here in Germany. I ended up ordering "grease TF silicone+PTFE" on ebay which is designed for plastic parts. Typical lithium-based grease can be harmful to plastic, and "Normal" Silicone grease here is weirdly solid and sticky and meant for O-Rings in Coffee-machines, not for lubricating moving parts.
@@Joekutz Nylon and POM aren't actually afraid of any grease you might throw at them as far as i know. And all your friction-prone moving plastic parts should be made from these.
Lithium grease isn't based on lithium, it's various kinds of grease (petroleum based or silicone base) with lithium soap as an additive that makes it stiffer and stickier.
@@SianaGearz I agree. I am not sure what type of plastic that was, but I know that many plastic mechanisms in devices are greased from the factory, and the turntable was no exception.
I don't know, i would have deemed that amount of wobble perfectly normal, a lot of turntables run like that :D
OK Technics shouldn't be running like that.
