Since I have the tabs open ,I will post the pages .

    This is type would be used in the head/ main bearing , but not small enough .

And this type for the tail bushing and handle side .

This is one of the reel done with a one way bearing ,but a lots of picture are not there any more .

My wish was for 330N and 331N. I can't exactly sit the dimensions of the ball bearing in the rotor. The problem is the dimensions of typical non-return bearings. In addition, the inner cylinder of the non-return bearing should be fitted on the pinion itself. The pinion itself is not sufficiently hardened in heat treatment to withstand braking without surface deformation. After a while the rotation would become rough.

Perhaps Fred can provide the dimensions of the factory ball bearing in the rotor head for the 330N?

Glad to —-

Will measure one tomorrow morning.

Best, Fred

I have already measured the main bearing , it is 8x19x6 mm.
   The smallest sprag bearing i have found is 8x22x9 .   there is not enough casting to make this work .

    Than i took a look at the handle .  The handle shaft has a step in it . Bottom one in the picture .  This could be replaced with a shaft from a quick ,but the shaft is not a true 7mm it`s more like 6.80 mm,
 
 Than there is the main shaft and it has a step in the end of the shaft .

Thanks Oldmeanjoe for measuring.
Everything seems to me that there will have to be a more complicated solution here...

I have some other ideas but they need time to be developed and tested. A solution with a non-returnable roller bearing would be the most elegant, but the question is whether it can be simply implemented.

If there are any other suggestions I will be very happy to consider them together.
