[TowerTalk] MA550-MARB Question

I have recently received my MA-550 with MARB rotator base from UST.  All 
arrived in fine condition.

Included with the base bearing is a collar with setscrew.  Collar is machined 
with an eccentric 'rabbet' (for lack of a better word) in one of the two flat 
sides.

The bearing has a mating eccentric machined on it.  The shaft of the mast is 
not large enough to  enable the collar's setscrew to fix it in position.

The OD of the shaft is 1 1/2", the ID of the bearing is 1 3/4".  Not exactly a 
sliding fit.  Can anyone tell me what's going on here.  Do I just discard the 
collar and drop the shaft through the bearing and go?  Or is there a bushing or 
something I'm missing.  I received everything on the Bill of Lading.


Thanks in advance
Gil, W1RG

Naturally it's Saturday.  Can't call UST 'til Monday.
