| + | === 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. \\ | ||
