Does it have a shaft bearing?  Or just the bearings on the ends?  I got one today and I can't find the bearing or a bushing on the shaft?  did the 100's come without a shaft bearing?   :-?

Part #194 (x2) supports the spool in the CU 100B, but you didn't say which "100B" you were talking about.  I can't think of any Curados that have a bearing on the spool shaft itself.  I'd have to go and check the other schematics to verify that, though.

Sorry, its a Curado 100B, CU-100B.

Yes, that reel has two BNT0194 bearings, one is in the left cover and one is under the cast control cap.  The other bearing through which the spool shaft passes is a BNT2170 for the pinion gear. There is also a tiny bearing under the drive shaft (BNT0031).

This is a really great reel and I wish I had bought more than three.

Sorry, its a Curado 100B, CU-100B.

The the two parts I listed are the spool bearings.  They get oil.  You can lube the other two with oil, but the reel cranks smoother if packed with grease.
