While on this bearing subject,
I have couple question:
What the reason was converted from sleeve bearings to roller/ball bearings at one point even these days can buy prepared sleeve shells?
Second on 2 cylinder listeroids didn't these use all sleeve or the number 1 and 3 is roller while number 2 is plain bearing shells if correct, how one maintain the bore-line alignment as not to stress the crank and wear out the bearings?
Cheers, Wizard
