[ARC5] A really WEIRD question...

I am rebuilding another derelict BC-454B here.

After fixing all the ordinary problems, I come up with a very, very stiff tuning capacitor.

So I removed the cover and discovered that some time in its past life, someone had hit this 
thing so had that the end of the rotor shaft on the opposite end from the drive mechanism 
had been forced completely out of its hub, and the teeny tiny balls had been scattered 
although the larger one was there.

So my WEIRD question: how many of those teeny tiny balls are supposed to be in THAT end 
of the spring-tensioner?

By sweeping a magnet back and forth across the floor, besides those few I had captured, I 
found 9 balls. 

Trouble is, I have taken apart two other caps, losing all the balls out of one and capturing a 
few from the other cap.

There were none inside the receiver, and besides, since there was only one screw in the 
cover at that place on either side of the mixer tube where there should be two, I suspect that 
the original owner of this thing had the cover off before I got it.

There is room in that race for 8 balls, but I suspect that there were never that many in there.

Can anyone help? I really don't want to replace the tuning cap if I don't have to.

I suspect that there were 6, but no more than 7 balls in there originally.
