      Can someone tell me what the correct diameter of the top bearing surface is? I have the pictured crank that I thought was a 20H crank. The bearing is marked ??7183 and is too tight. I get about .98 on the crank itself and about .93-.94 on the bearing.

        I see now – ball bearings at top and bottom plus roller bearing at top. All in the White Pages on the JOM site
