Does anyone know if I can knock out the one way bearing in a kalt baron 30 clutch. And replace it with anything else more modern?
Thanks

What hub do you have ? If this hub has a radial bearing on top and bottom, the hole in the center where the one-way lives is smaller in diameter than the OD of the radials. You have to punch out the radial bearings first inside out. I use a 1/16 center punch and whack the inner race of the radial bearings at an angle from the opposite side. They are not very tight. Replace them ! Then you can press out the one-way. It is just a standard one-way like in the TREX 500 auto hub or the TREX 600 clutch. 10 mm ID x 14 mm OD x 12 mm H. Put all three new bearings in with some Loctite. Blue is good enough. The radials are the same size as TREX 600 main shaft bearings - 10 x 19 x 5.

If this does not sound right post a picture of your hub.

OK, I'm not awake yet. That is just a 6 x 10 x 12 one-way. Boca has them. Be sure and get one with stainless steel springs.

My first post is still valid for the autorotation clutch in the main gear.

Your 100% correct on the measurements. I just checked them with my calliper.
Thank You Good Sir, you saved me much headache & night sweats.

Well I believe I found them, but the one in the pic does not look like mine, plus the one with the steel springs are out of stock.
