VPI Classic motor question


I have a Classic with the 600 RPM motor. The table is 2.5 yrs old. The motor started making a swooshing sound on each rotation about a year ago which continued after lubricating it. The sound could only be heard with the ear to the pulley and the speed stability seemed fine with the SDS. I lubricated the motor again about two weeks ago, including removing the pulley and cleaning the shaft, and the swoosh continued. Today I started hearing a more frequent noise that sounds like a very low friction sound. Still very low, but what the hell?

Is there is anything I can do about it at this point? I don't think putting more oil into the motor after I just lubricated it will fix it. If the speed appears to be ok, should I just ignore it? The first time I heard the noise VPI did not offer any advice beyond lubricating the motor. Is replacing the motor the only way to take care of the problem perhaps?

Any advice and feedback would be appreciated.

Brf,

I called them all day yesterday, but apparently only Mike is knowledgeable enough to give advice on the motor issues, and he was not there every time I called. I'll probably give it another try tomorrow.
Every time I called Mike was not there. I asked the person who answered the phone whether he could help me, but he didn't even know whether replacing the motor entailed soldering, and whether the shaft should be all the way up or down. After asking other people there, he said it should be all the way down, which is the opposite what someone said Mike had told them. So back to square one.
Try it all the way down, and then slightly up from the down position. That is how I do it and it works. Give it a try, you never know.
That's what I did. There is still a little bit of swooshing sound coming from the motor, but it's quite low. The playback does not seem affected so I'm going to leave it for now. Perhaps the oil needs to settle a bit more. Thank you all of your advice.
