REBUILD
SECONDARY SHAFT ASSEMBLY
NOTE: In all NL gearboxes, the "Z-shaped"
BORG-WARNER (3rd/4th speed) synchro roller
springs used to date have now been replaced
in production by "heart-shaped" springs.
1 : 1st type of assembly ("Z" shape)
2 : 2nd type of assembly (heart-shaped)
The inlet recess chamfer (E) of 3rd and 4th speed
idler synchro cones has been redesigned to
accommodate the new shape roller spring. The new
springs can only be used with the new design idler
gears. They will not work with old design idler gears.
