Installing First and Second Gear Shifter Shaft
1. Inspect shifter shaft carefully for burrs, and
remove with emery cloth. Burrs on shifter shaft will
prevent easy installation of shifter yoke and cam.
Lightly oil with transmission oil prior to installation.
Insert first and second gear shifter shaft through hole
in rear of case with three notches down and toward
rear of transmission, pushing shaft
through
and second gear shifter yoke, which should be posi-
tioned on and second gear sliding gear with
shoulder toward front of case. To position and
second gear shifter yoke on and second gear
sliding gear, push reverse idler gear forward, engag-
ing the idler gear with the first and second gear
sliding gear. This will make room for positioning
and second gear shifter yoke. See Figure
2. Continue to drive first and second gear shifter
shaft through shifter shaft cam, which should be
positioned as shown in Figure
3. Install spiral pins to secure shifter yoke and shifter
shaft cam to and second gear shifter shaft.

remove with emery cloth. Burrs on shaft will prevent
easy installation of intermediate levers. Lightly oil
with transmission oil prior to installation. Insert new
selector shaft oil seals in holes on both sides of trans-
mission case and insert selector shaft into case and
through third, fourth, and reverse intermediate lever.
Third, fourth, and reverse intermediate lever should
be positioned on selector shaft, as shown in Figure
2. Continue to push selector shaft through first and
second intermediate lever and through other side of
case. First and second intermediate lever should be
positioned on selector shaft, as shown in Figure
52. Selector shaft is rotated counterclockwise (when
looking from lever end of selector shaft) from work-
ing position to have spiral pin holes in shaft vertical
and in line with pin holes in intermediate levers. To
rotate selector shaft in this manner, the reverse gear
shifter shaft and its reverse speed shifter yoke must
be pushed rearward so that the reverse idler gear is
against rear of case.
