INSPECTION
Thoroughly clean and carefully inspect all
parts for wear, nicks, scores, etc., to determine if
any parts need replacement.
Regardless of appearance, all oil seals and
gaskets should be replaced to prevent the possibil-
ity of oil leaks.
To replace the mainshaft rear oil seal (42),
drive old seal from rear flange and install a new
seal, tapping it into bearing retainer from rear of
retainer using Seal Installer Tool J-1354.
The rear face of the seal projects 1/4" out of
retainer when properly installed.
The shift shaft oil seals (52) are replaced by
driving the old seals out from inside of transmis-
sion case and driving new ones in from outside of
case.
NOTE: When installing new .oil seals, it is
good practice to coat the outside diameter of
the seal and the inside of the housing with
white lead or gasket sealer to prevent oil leaks.
Leather seals must be soaked in engine oil for
24 hours before using .
The mainshaft second speed gear (10) and the
reverse idler gear (22) fitted with bronze bushings
must be replaced with a gear and bushing assem-
bly if excessive wear is noted, since replacement
of bushings in the field is impracticable.

main shaft rear bearing (34) appear rough or show
excessive wear or damage, they should be re-

ASSEMBLY
SHIFT SHAFTS AND INTERLOCK
1. Install the low and reverse shift shaft (49) Figure 2,
in the transmission case. Use care to avoid damage
to the oil seal, align the neutral detent of the cam
with the interlock boss opening in transmission case
and install the taper pin (45) through shift shaft and
case.

NOTE: It is necessary to install low and reverse
shift shaft (49) first due to interference by the boss
of the reverse idler gear shaft.
