Shimano One Way Roller Clutch Bearing - Replaces Part Number BNT2949

This is the roller clutch bearing in my Shimano Chronarch 100A. How do I flush/lube this bad boy? One drop of hot sauce for the whole thing or does each individual roller need a little love?

 

I appreciate the feedback---- does anyone have any recommendations on how to apply an appropriate amount of oil?

I always clean it off good with a q-tip then  soak a q-tip with oil and go around each one. Don't know if this is correct but my reels still work great.

 You can soak it in a degreaser or cleaner if you want but it isnt necessary. It doesnt spin.  Dont  use grease at all . Take the tiniest drop of oil and then use half of that and then use half of that. AR bearings can be tempermental to over lubrication.

Soak it in mixture of hot water and a degreaser like purple power. Then rinse thoroughly with warm water. Let it sit out and dry or use some compressed air. Add 1 small drop of oil to a q-tip and run it around the inside of the bearing a few times.

brake cleaner best degreaser ever

Terrible idea on fishing reels, or anywhere there is the chance to come in contact with plastic, paint, or anything you don't want to melt. QD electrical parts cleaner is a much better "flush in a can" solution. It is safe on plastics, and finishes, and it comes out of the can at high pressure like break cleaner to "blast" away grime and gunk, plus it evaporates on it's own in a few minutes.

Call me crazy but I take my bearings out of the reel before I clean them.

CNC Brake Cleaner, while not my normal solvent for cleaning bearings, is a great product that can get those stingy bearings clean. Used it from stock bearings up to Boca ceramics. Never had an issue.

As do I ...................most of the time, but sometimes like in mid-season, I will give them a little blast of cleaner, and let dry before re-lubing, and by using the QD electronic parts cleaner I can do so without having to worry about it. I have found , even during a complete tear down and cleaning it works as well as break cleaner, and without any of the potential harmful side effects.

I use brake cleaner all the time on the various metal components on my reel. I've also used in the past for anti-reverse bearings with their plastic bearing holders. I've never had issues. Nonetheless, it's not a bad idea to be careful by selecting a mild solvent when plastics are involved. In addition to the electrical cleaner mentioned, Isopropyl alcohol would probably be pretty safe too.

One other thing I usually do with the anti-reverse bearings when cleaning is to remove the individual rollers from the plastic holder so both can be cleaned separately. This can easily be done with a large pin or dental pick, or  some cases, the whole plastic holder can be removed and the rollers will drop right out. However you do it - just don't lose the rollers! When reassembling the bearing, I very lightly lube the rollers prior to reinsertion. When it's all back together, I give the whole bearing a drop or two of oil.

It's pretty cut and dry stuff to me... far from rocket science.  If you understand what you are doing and how the bearing works, there's nothing to it. If you are mechanically challenged, maybe you're better off staying away from fixing your reel.

The reason I do it is because some manufacturers, for reasons unknown, choose to load the a-r bearing with grease (Daiwa in particular comes to mind). I want to be sure there is no residual grease hiding behind the rollers. Removing the cage and rollers and cleaning them assures that all the grease is gone.

The only part I disagree with is the need to disassemble. Shielded bearings are greased too and they can be flushed thoroughly without tampering and a roller clutch is no where near as tight. Every time the rollers are popped out and pressed back the fitting is stressed to some degree. Like I said though there's more than one way to skin a cat.

Flush them out in your favorite way. I use WD40. Then think of the smallest amount of the lightest oil you think is barely sufficient, then use 1/10th that much.

I am playing with a Black Max I, made in the USA. The side plates are plastic with a pressed-in or molded-in anti-reverse bearing. Not wanting to expose the plastic to anything harsh, I used warm water and Dawn. This worked well!

Yup. Simple Green, perfect solution etc will do as well. I also dip in alcohol to displace raining moisture and speed drying.

Call me crazy but doesn't that bearing in the picture have a plastic cage? Like most AR bearings?

Crazy.

 The comment was in reference to the person I quoted pertaining to using brake cleaner at all, not the OP. 

Also,  not all  AR  bearings contain it plastic or rubber gasket/housing.  It's unnecessary almost always to remove the Bearing from the reel during a breakdown/clean. If you do, you're doing it for a particular reason and disassembling the bearing...hence,  why brake cleaner is OK to use it when you take them out .

I'm talking about the cage inside the bearing that holds the rollers like in the picture above. That bearing can't be taken apart.
