new seal and plug will not be covered under warranty.
INSTALLATION
1. Remove the oil ll and drain plug in the top of the reducer
and completely drain the oil from the reducer into a clean
container.
2. Lay the reducer on its side with the bearing cover facing up.
3. Loosen and remove the four bearing cover bolts and
lockwashers.
4. Rotate the bearing cover suciently to be able to get a screw
driver between the bearing cover and gearcase housing.
5. Remove the bearing cover using two at-blade screwdrivers.
Keep the bearing cup and shims together and do not mix the
shims with any shims that might be installed with the bearing
cup on the opposite end of the output shaft.
6. Lift out the output shaft assembly and place it on a clean
surface.
7. Remove and discard the output shaft seal, taking care not to
damage the machined bore in the bearing cover or gearcase
housing.
8. Remove and discard the output bore plug, taking care not to
damage the machined bore in the bearing cover or gearcase
housing.
9. Remove and keep together the remaining tapered bearing
cup and any shims.

10. If changing to Shaft Position “L,” clean the bore in the
gearcase housing and install a new output bore plug in the
gearcase housing. Clean the bore in the bearing cover and
install a new output shaft seal in the bearing cover. Install
the plug and seal 1/16” below ush with the outside of the
gearcase or bearing housing.
11. If changing to Shaft Position “R,” clean the bore in the
gearcase housing and install a new output shaft seal in
the gearcase housing. Clean the bore in the bearing cover
and install a new output bore plug. Install the plug and seal
1/16” below ush with the outside of the gearcase or bearing
housing.
12. Remove and keep together the tapered bearing cup and
shims from the bearing cover and place them in the gearcase
housing bore. Place the tapered bearing cup and shims that
were previously removed from the gearcase housing and
place them in the bearing cover.
13. Wrap vinyl electrical tape around the entire output shaft
extension to protect the lip seal during assembly. Do not
extend the tape onto the portion of the shaft which the seal
contacts during operation.
14. Apply a small amount of reducer oil drained in Step 1 to the
taped shaft extension to help slide the extension through the
output seal. If the reducer is being changed to Shaft Position
“R,” place the reducer housing on blocks to provide room for
the shaft extension. Insert the output shaft assembly, shaft
extension down, into the reducer housing. If the reducer
is being changed to Shaft Position “L,” insert the output
assembly, shaft extension up, into the reducer housing.
15. Remove the original o-ring from the bearing cover and install
a new o-ring.
16. Install the bearing cover onto the gearcase housing. If the
bearing cup and shims fall out of the bearing cover, apply a
liberal amount of oil to the bearing cup’s outside diameter and
reinstall the bearing cup and shims into the bearing cover.
The oil will hold the parts in the bearing cover.
17. Install the four bearing cover bolts and lockwashers and
torque the bolts in a cross pattern to the following values:
Reducer
Size
Bolt Torque
(Inch–Pounds)
13 75
15 75
17 156
20 156
23 276
26 276
30 420
35 420
40 1320
47 1320
18. Remove the vinyl electrical tape from the output shaft
extension and place the reducer with the ll and drain plug
hole facing up.
19. Fill the reducer with the oil drained in Step 1. Install and
tighten the oil ll and drain plug. Standard temperature range
replacement lubricant is available from Dodge. Contact
Dodge Product Support for details.
CAUTION: Do not substitute or add any other kind of oil or
premature reducer failure may occur.
