SATURN INSTALLATION PROCEDURES
5.
Lift both rear wheels off the ground. Put transmission into neutral, transfer case in gear and release the hand brake. Turn
driveline by hand to check for free rotation and run out. If rotation is not free, recheck Step 3 & 4.
(Fig. 3)
(Fig. 2)
(Fig. 1)
1.
Drain and flush transfer case before starting with installation.
2.
Put transmission into reverse gear and set hand brake. Remove shift knob, floor mat,
and transmission floor plate.
3.
Clean the transfer case and P.T.O. unit (if installed). Remove the rear cover plate or
P.T.O. unit and clean all surfaces of gasket material and burrs. Using a socket
wrench, remove the retaining nut that holds the stock drive gear in place. Remove
the main drive gear
(Fig 1)
and make sure the new planetary gear assembly
(Fig.
2)
has the same number of exterior & interior teeth. Check the transmission main
shaft for end play and the transfer case intermediate gear assembly. Replace any
worn bearings and inspect the transmission rear output shaft bearing, replacing if
necessary.
(If installing Model No. 915674 overdrive unit, be certain that the spacer
between the transmission output bearing and the main drive gear is not removed. This
spacer is only on the T14 3 speed transmission).
4.
Install the planetary gear assembly onto the transmission main shaft. Using 1/2” socket
drive, tighten the drive nut to 100-120 ft./lbs. torque.
DO NOT USE an impact wrench. Install
the special lockwasher
(Fig. 3)
. This lockwasher prevents the drive nut from loosening.
To retain the lockwasher, we have also provided a square snap ring that fits into the snap
ring groove inside this planetary assembly. These items must be installed to prevent
premature failure of this unit.
Square snap ring installation:
a. Use "snap ring" or "needle nose" pliers to install.
b. Compress the ring until the two ears touch. (If compressed beyond this point, the ring will collapse and will
not be suitable for use).
c. After installing, DOUBLE CHECK and make sure the retaining ring is properly seated in its groove.
NOTE: If the snap ring is not properly seated in its groove, the planetary unit will eventually work loose on the main shaft and cause
severe damage to the overdrive unit.
