Does anyome know the bearing sizes for these reels lpoking to replace them all but need the bearing sizes before I can order. Thanks for any help you can provide!

Check or call bocabearings if if you can't find it there or get your answer here you can always buy a cheap pair of vernier calipers and measure the inside, outside diameter and width and find a comparable bearing. I take the measurements 10 times for each spec and take the average. The bearings are sized in millimeters.

For spool and pinion bearings, they use 2@ 3x10x4 and 1@ 5x11x4,  I would suggest you try flushing and using a good light bearing oil on the factory bearings, there is very little to be gained by replacing the excellent bearings already used on the Lew's reels. You should do this before you change them out so you realize how little you gain for the cost, if any gain. One other thing, if going to ceramic, enjoy the noise, or, if you use a drop of oil to quiet them, you might as well stick with SS in the first place, because you are defeating your purpose By Oiling a Ceramic Bearing, it quiets it, and at the same time, slows it down!! Try the flush and proper lube first with whats in the reel, you will see an improvement, I think you will be quite happy!

I agree with the above. The one quantum reel (the 2012 Kinetic? I think..it's red and was a gift) was awfully slow on the start up and just wouldn't ever get going. It had a mess of grease and very dirty bearings. I just soaked the bearings over night. (Normally it only takes less than 10 minutes but I kept getting dirty acetone after cleaning them repeatedly. This did the trick. Reel casts fantastic.

I second the Capt's opinion here. Oiling ceramic bearings is the equivalent to putting performance exhaust on a bike then adding a throttle stop. The smoother/harder surface of ceramics that gives them better speed also reduces wear. The metal races will probably wear first but won't be any time soon.
