I just service a 10-plex with Christie AW3R platters, I notice on a couple of the screens the bottom platter the removeble center feed is hard to install, where the Middle & Top platter will slide in & out very easly as it should, thinking there was a build up of dust, grease ect, I tried cleaning but the center feed was still hard to install & remove, it is as though the axle was bent (which it is not) I can't figure this one out, it is happening always on the bottom platter on more than one screen....anyone has any ideas to correct without changing the axle ??

I am assuming that you are using the older style brains. Try getting some 40-grit sandpaper and sand down the stem on the brain and inside the hole on the deck. I could be wrong though.------------------

Randomly using 40 grit paper--come on!use your fingers to feel if there are any burrs. A light coat of sewing machine oil might help. To check for burrs, paint the pay-out head stem with dycum or similiar product which, along with a flashlight and inspection mirror, can help to reveal burrs.
It may also be a tight fit because that bottom deck is not used often and may still be tight?

Don't use the sandpaper inside the axle, but DO use it on the base of the removable brain. Yes Will, this trick does work and it works magnificently. The older model AW3R platters where the center axle of the arm stands just a bit higher than the surface of the deck were machines just a bit too precise and especially in a high humidity area, just the tiniest amount of rust can cause them to "jam" and be hard to insert/remove. The sandpaper trick works perfectly, just make sure you wipe off the bottom stem of the brain well before you insert it into the axle.Get a brain from another screen. Odds are that you will find some brains fit easily into that bottom deck. No two are perfectly exactly alike.

I agree with Brad on this one.
