carpet squeak

[Brunsamf]

After rebuilding the pits this summer, 3 of the 12 carpets make a chirping noise on the non ball door side. At first I thought is was the rear roller bearing rubbing on the side plates. The half moon rubber supports are good. I can see no metal to metal contact anywhere. It is not the humpbacks or any related parts. If I reach under the plank and pull back the carpet so I can see the bounce plate,{they are masonite} and spray soap based cleaner on the bounce plate , or babby powder works best, it will run quiet for an hour or so but slowly comes back and starts squeaking again. It's 1,9&12 so odd or even makes no difference. Lane 9 is a Sthal's pumpkin carpet and the others I'm not sure. This has never happened before and it's driving me and the owner nuts. We do not use grounding straps. Are they important? Could it be static electricty? As I said, baby powder works best for a short while. Please, any ideas? BTW the angle plate is tight and square.

Re: carpet squeak

Did you put new bearings on the BE carpet roller while rebuilding your pit?
I've had a squeek caused by NEW bearings, asked for others and problem was gone.
Try another, or swap two carpet rollers and see(hear)what happens..
It helped me.
Good luck.

Re: carpet squeak

Before putting new bearings on.....the new bearings need washed in a slvent tank.....dried....and packed with new grease.....they only put a small amount of grease in a new bearing.

Re: carpet squeak

I've never washed them out but i agree, you need to add grease, they don't have hardly anything in them from the factory (much like the u joints for the distributor drive shaft that have springs holding the boot on). On most of those bearings I also add a few drops of gearbox lube and then pack in the grease, I'm probably going to switch to lucas motor oil treatment, that's good stuff. No idea if this is good practice for that type of bearing but it has worked well for me.

<font size="2" face="Verdana, Helvetica, sans-serif">We had this problem here with the "birds chirping" and it turned out to be that the rubber inside the carpet was a little exposed causing it to rub on the smooth surface of the bounce board. You'll probably need to change the carpet (or the bounce plate). For a quick fix, get some gaffer's tape and spread on common side of the bounce baord. As carpets get old and soft, this problem tends to show up. It will only do it on the common side as it is higher and makes more contact with the carpet.

Re: carpet squeak

I throughly clean my bearings out with diesel fuel; dry them, then pack them with a high quality grease.

Re: carpet squeak

Kat, you were right on about the chirping birds. I also work at a BRC center and we have thick 4 inch wide plastic tape to make a temp. fix on split deck buckets. I peeled off the backing and stuck it to the high side of the bounce board and angle plate. No more birds! Have to keep an eye on it. when it wears down, it will be a gooey mess. thanks much! Bill
