Over the years I've tried various oils etc to lube noisy/dry capstan bearings
with little luck. I get tired of replacing perfectly good albeit dry bearings.
I see Lubriplate is good to 350 degrees. Anybody try it or find something that
lasts and doesn't gum up in a couple weeks?
I have a perfectly good SLV696HF Sony here with the notorious capstan bearing
problem, caught before the bearing and motor ruined, but it definately is dry.
Thanks,
Ron

Lube won't help with the Sony capstan bearing. MCM sells a replacement
bearing kit for about $7. Part # X-2625-356-2. The only problem, I think they have a$25 min order. Maybe you can try www.iglou.com/studiosound I'm
sure they don't have a min order.

The Sony capstan problem is not because the bearings go dry. It's because the
metal casing that contains the bearings is known to warp, which tilts the
capstan rotor and causes it to rub against the stators on the capstan motor
circuit, which is the source of the scraping noise.

The only solution is to replace the capstan bearing assembly on the capstan
motor module.

This is not a lube problem. - Reinhart

Thanks for the replys. I guess I should clarify I'm not speaking entirely about
the Sony, I've got the bearing for it. There's been multiple instances of
binding motors causing either capstan overheating or that horrible vibration on
rewind on various other VCRs. Every case in disassembly the same thing is
found, the lower bearing all gummed up. Clean the gum off, reassemble
dry=problem back in a few days. Reassemble using various oils/grease=problem
returns in a few days. Replace bearing=problem fixed. Problem is not all
capstan bearing are available. Seems a shame to throw away a VCR when I'm sure
there is some kind of lube that would work on these bearings.

Lube won't fix the problem when you have worn out sleeve bearings made of
brass. There are some suppliers that sell replacement brass bearings. In a
pinch, pop the bearings out of a good, used capstan motor & use those.
