★ Essential component for correct operation of the manual transmission. Replacement necessary in case of wear, corrosion or incorrect detent operation.
Installation notes
Ensure correct positioning of the detent notches relative to the poppet ball and spring. Check that the rail moves smoothly in the housing without lateral play. Ensure that the interlock pin can move freely. Bristol set screw in the shift fork must be tightened securely with lock wire.
Compatibility
Not all shift rails are interchangeable - reproduction rails may be incorrectly milled or not run true. Check before installation that the rail rolls across a flat surface without wobbling effect. Overly tight rails may seize in the housing.
Historical context
Shift rails in WWII transmissions were often manufactured by Warner Gear (Borg-Warner) and had to withstand extreme conditions. Corrosion of the detent spring is a common cause of failure in transmissions that have stood idle for extended periods.
