SCOUT PINION MODIFICATION FOR WARPATH PINION RACE We can now repair any Sport Scout pinion that is loose and we can replace the stock pinion race with the WAR PATH pinion race which is a direct replacement for the 648 big base pinion race. This requires removing the shoulder in the pinion area but it allows the cases to be line honed with the drive race to insure perfect alignment and the utmost horsepower efficiency. This War Path race is available for $200. The installation includes boring out of the scout case and honing hole for a .0015 to .0020 shrink fit with the new race. Then the cases are assembled with our cylinder deck plates and line honed with our special stepped thru hone for War path engines. We have capabilities of measuring and sizing our bearing races to +-.0001. You can supply your parts so we can measure or you can supply measurements for us to work by. The labor for this procedure is $250. We use Federal .0001 Bore gages calibrated to an ISO standard.
