Drive Shaft Assembly
1.
Press needle bearings (T6) into each end of bore of drive sprocket (T5)
(see note below), setting them back from each face 1/8 in. Press sprocket,
coupling teeth end first, onto drive shaft (T13).
NOTE: One end of the O.D. of the cup of the needle bearings (T6) is
rounded. These bearings should be installed in the bore of the drive
sprocket (T5) rounded end first.
2.
Press spacer (T7) and bearing (T15) on shaft against shoulder at drive
sprocket (drive sprocket should rotate freely on shaft after installation of
the bearing).
3.
On case with 2.35” drive line built prior to 2/10/00, install snap ring (T105)
and spacer (T104). On cases built after 2/10/00, install spacer (T239).
NOTE: It is recommended if rebuilding cases older than 2/10/00, to
replace snap ring (T105) and spacer (T014) with spacer (T239).
4.
Press appropriate tachometer gear (T10) or spacer (T230) and oil seal
sleeve (T14) on drive shaft. Press bearing (T3) on coupling shaft end of
drive shaft.
5.
Apply bead of silicone to oil seal seat area of drive shaft housing and
install oil seal.
6.
Apply a light coat of grease to face of drive shaft housing (T11). Position
gasket (T17) in place on the housing (T11).
7.
Press the drive shaft housing (T11) on bearing (T15) on the drive shaft
assembly.
8.
Place this assembly aside for later installation.
Coupling Shaft Assembly
1.
Stand coupling shaft (T44) on press table with spline end up.
2.
Press on inner bearing (T1 - prior to 4/25/1993) or (T15 - after 4/25/1993)
tight against shoulder on coupling shaft.
3.
Slip spacer (T2) over shaft (T44) and seat it against bearing (T1) or (T15).
4.
Press on outer bearing (T1 - before 4/25/93), (T184 - 1/04/94 to 4/01/95)
or (T15 - after 4/25/95) tight against spacer (T2).
5.
For 2” drivelines and heavy duty cases built before 4/01/95, press oil seal
sleeve (T14) tight against inner race of bearing (T1) or (T15). For 2.35”
drivelines built after 4/01/95, no oil seal sleeve is used.
6.
Apply bead of silicone to oil seal seat in (T42) and install oil seal (T45).
7.
Lubricate lip area of the oil seal (T45) and install the coupling shaft hous‐
ing (T42) onto bearings (T1) on the coupling shaft assembly.
8.
Place this assembly aside for later installation.
Case Mid-Section Assembly
1.
Press bushings (T50 before 7/01/96) or (T50 and T190 after 7/01/96) into
the mid-section shift shaft hole with top bushing flush with pad on the
mid-section and with 1/8” space between the bushings (T50). Install
O-ring (T49) in the space between the bushings.
2.
Install pins (T60) in shift arm (T62) and in the case mid-section if pre‐
viously removed. Install pivot pin (T37) if previously removed.
3.
Invert mid-section. Install O-ring (T39 in groove on pivot pin (T37). Install
locking arm assembly (T38) on pivot pin (T37). Install with pin facing up
and position as shown in Figure 4.
4.
Position spacer (T48) over shift shaft opening.
5.
Electric or Manual Shift -
Position sector gear (T47) on spacer
(T48) with teeth meshed with locking arm as noted in Figure 4.
Pneumatic Shift -
Install actuating shift lever (T173) in sector gear
(T47). Ensure holes in shift lever and sector gear are aligned. Position
sector gear (T47) on spacer (T48). Shift lever (T173) will protrude from the
rear of the case. Mesh teeth with locking arm as noted in Figure 5.
