VPI Rim Drive vibrations

I had updated my plinth feet to TT Weights brass Soundpoints before adding a single motor rim drive flywheel so never heard of this issue before.

In order to help seat your belt in the flywheel track, place a round toothpick or other small diameter object (small drinking straw etc.) between the flywheel grove and belt. Run this around the flywheel circumference a few times. Make sure you keep the belt even to the grove as you navigate around the circumference. You should be able to seat the belt evenly in the grove. I use a small diameter wooden cylinder I borrowed from the kids.

I also see you have the brownish rim belt for the flywheel. Does your flywheel make any noise when it touches the platter? Regardless of the contact pressure, my flywheel makes a high pitched noise. I have tried a few things to reduce/remove the noise but cannot eliminate it.

Maczurak, I did try to seat the belt with a round polished pin - it made the wobble less visible but still...No, there is no noise at all.

I hope to receive 4 TerraCone for VPI SSM Height-adjustment hardware Point-receivers from Eden Sound in the next few days and will post an update.

Macauak....That's what Harry told me....didn't work. The cure I noted above is the only way to completely solve the problem that I know of. The increase in purity, dynamics,
soundstage, etc. is magnitudes better than stock.

Krell303,

My belt must have an even diameter as I really don't have any wobble issues once it is seated using the above method.

Stringreen,

When I received the single motor flywheel rim drive, I had already replaced the VPI feet and plinth so this issue was new to me.

When I have some free time, I will have another go at the rim drive belt noise.

Just thought of this. I have the Super Platter and the rim drive contacts the stainless steel. I will try changing the height of the rim drive so it contacts the acrylic instead as see if this eliminates the noise.

Maczurak, the belt itself might be perfect but it's almoust impossible to put it in the rim 's groove evenly. Small differences in belt's tension around rim's perimeter cause variations in the belt diameter - thus causing vibrations on contact with platter
