RCBS Tumbler (I Need Help)

[ace4059]

If you have an RCBS vibratory tumbler can you look at the bottom through the vent and see if the fan is directly over the long screw that hold the bowl on, or is the fan offset 2" to the side of the main screw that holds the bowl on?

RCBS was gracious enough to replace my motor. Great CS BTW. I got it in the mail today and I replaced my motor on my tumbler and cant remember if it installs over the center of the screws or is offset. I should have took a picture before I removed it. It will install both ways. Inline is smoother running and offset is more tumbling but violent. If I get it wrong it could be either less cleaning action or worse wear out the bearings in the motor quickly.

ETA: if you could post a pic that would be greatly appreciated.

I snapped some pics

Motor shaft and fan is centered beneath the vent. Cant seem the shaft for the cover.

Cover removed. Fan is centered. The screw that holds on the tumbling bowl is directly on the other side of the motor shaft.

Cover removed and motor turned. Fan and motor shaft is offset. Screw that holds bowl on is under the motor coils that is covered with the yellow insulation. ETA: Yes the fan looks like it would hit the tumbler housing but it clears with plenty of space. It is just an optical illusion of the photo.

Is pic #2 or #3 correct?

Here is an update in case anyone has the same question later on.

A RCBS engineer contacted me and he said they ship with the fan centered. He said you will get more aggressive cleaning with it offset but you may have problems with the tumbler "walking".
