Got my bail ball bearing kits from Hedgehog.
They ship fast! Expensive shipping costs but fast .
I stalled four of them in my Shimano Nasci 500 reels and the other kit in one of my Sahara 500 reels .
If you’re going to do this , make sure you have a good screwdriver.
I own a couple gunsmithing tool kits and was able to select the correct screwdriver bit for the job .
Even with the right screwdriver, it’s a jog getting the bail roller crew out . They must tighten those things mechanically at the factory .
Finding the right hold took a little trail and error , but by the time I’d done the third one , iwas knocking them out .
Took about an hour for all five .

Results ?
Well, I can see the roller move when pulling line off the reel and the drag seems smoother .
If it makes the drag smoother it’s worth the $12.50 I have in each kit , with shipping .

I got to looking a the Nasci 500 schematic and best I can tell it has one ballbearing in the outside of the handle knob .
I’m not sure putting an inside bearing will make that much difference.
My washers and other bearings should be here the first of the week .
I’ll try one and check it out . I can always put them in my Sahara 500 reels , or maybe one of my Daiwa reels . I’ve read Daiwa and Shimano can use the same bearings .

I’ll report if it makes a difference next time I go fishing.
