 +=== Mainshaft roller bearings ===
 +Standard rollers should measure .15625"​-.15610"​. ((Dr Dick of the XLFORUM http://​xlforum.net/​forums/​showthread.php?​t=1601769&​page=2)) \\
 +Fit to shaft may not be determined by race size. \\
 +In order to fit 23 new std rollers in the race, it needs to be big enough to accept 23 rollers with out the rollers binding in the race. \\
 +When sized to the min. dia. that accepts 23 rollers with out bind, the shaft (.991" dia) will be will be about .002 running clearance. \\
 +This is because there is no roller cage. The rollers touch each other. \\
 +Because of the zero% roller to roller space trying to fit 23 o.s. rollers means the race needs to a lot bigger than the roller amount of roller o.s. \\
 +This results in a looser running fit than used in the standard rollers. \\
 +To use the os rollers and get a tighter fit than 23 standards, you can only use 22 o.s rollers. \\
 +Rigid hone / line lap race to take 23 standards. \\ Then let clearance be whatever it is. \\
