[TowerTalk] Yaesu GS-065 thrust bearing

[Mike Reublin NF4L]

Thanks, Grant -

MM-C is the goto place for sure. I just need the size.

I meant to type crufted. Autocorrect changed it. We used the word cruft in my programming shop to mean junk. If code was crufted, it was fubared. Autocorrect changed that to fibered......AAARRRGGhhhhh

73, Mike

Works for rotator races.  Adding a couple of grease fittings which get a shot of grease every year will also help a lot.  I like the TFE loaded full synthetic "Super Lube" formerly by Synco, now owned by Loctite.
