9. Press output driveshaft out of transmission through bearing in
transmission case. Oil seal should also press out at this time.
10. Remove bearing cone from driveshaft. Inspect driveshaft for chipping
and/or cracking around Woodruff key area. If any damage is evident,
replace driveshaft.
11. Inspect driveshaft in location where inner portion of oil seal contacts shaft
for concentricity, scratches, chips or other imperfections.
If depth of any
groove cut into driveshaft is greater than .010 inch (0.25 mm), replace
driveshaft.
NOTE: Unless inner sealing member of replacement oil seal turns on a
concentric, smooth surface, oil will continue to leak.
12. Inspect replacement oil seal area where driveshaft rotates within seal for
scratches, chips or other imperfections which can cause oil to leak past
seal. DO NOT use seal if any imperfections/damage is evident.
13. Pack cavity between inner and outer sealing members with Barium or
Lithium based lubricating grease to minimize possibility of dry oil seal
rotating on dry driveshaft during first few minutes of operation.

NOTE: LUBRIPLATE 105 is an approved lubricant.
14. Inspect transmission case oil seal cavity for signs of galling or shape
distortion. Coat oil seal outside diameter with bearing/shaft, locking
grade, anaerobic adhesive/sealant to help retain in position.
15. Slide oil seal over circular spacer of driveshaft with circular, twisting
motion. The crimped side of oil seal faces away and opposite threaded
end of driveshaft. DO NOT cut or nick oil sealing lips when installing
seal.
16. Clean and inspect both bearing cones. Replace if excessive wear is
evident. Repack both bearings with a suitable wheel bearing grease.
Reinstall lower bearing cone on driveshaft against spacer.
17. Position transmission case on shop press with bottom of case facing up.
Make sure case is not supported on any alignment dowel pins. Use
Service Tool to press oil seal/driveshaft assembly into transmission case
until firmly seated against machined shoulder. FIGURE 33
FIGURE 33
IMPORTANT: Cocking seal in the case contributes to seal failure. The service
tool has approximately a 2.431 inch (61.7 mm) outside diameter. The inside
diameter of tool is approximately 2-1/4 inch (57.2 mm). Apply face of service
tool to the crimped bead of the oil seal. Too much pressure too close to center
of the seal will distort or damage it.
18. If an arbor press is not available, tap oil seal into place with thin, wood
block and plastic hammer. Position seal against machined shoulder of
transmission case with bore at right angles to shaft. FIGURE 34
IMPORTANT: Keep blows to outside edge of oil seal to prevent damage. DO
NOT hit oil seal with direct hammer blows under any circumstances.

19. Reinstall upper bearing cone, Nilos ring and Woodruff key on driveshaft.
Coat Woodruff key area of driveshaft with light oil, Barium or Lithium
based lubricant.
20. Reinstall large spur gear and flat washer.
21. Apply small amount of anaerobic adhesive/sealant to protruding threads
of driveshaft.
22. Torque 1-1/4 inch (31.8 mm) self-locking nut to 60-70 foot pounds (81-95
N.m.). Determine flat washer is tight against large spur gear and is seated
against Nilos ring. If not fully seated, use thin wooden block and plastic
hammer to tap gear down into place. DO NOT , under any circumstances,
hit large spur gear with steel hammer.
23. Tap both ends of driveshaft with plastic hammer to help set bearings.
Loosen 1-1/4 inch (31.8 mm) self-locking nut and retorque to 60 foot
pounds (81 N.m.). Recheck to determine flat washer is tight against large
spur gear. Tap both ends of driveshaft with plastic hammer to help set
bearings.
24. Attach torque wrench and 1-7/16 inch (36.5 mm) socket to 1-1/4 inch
(31.8 mm) nut and rotate slowly to a maximum bearing drag of 30 INCH
POUNDS (3.4 N.m.). This value should allow a MAXIMUM .003 inch
(0.076 mm) of freeplay in the bearings. A greater amount of bearing drag
will significantly decrease load capacity of bearings and contribute to
premature bearing failure. If bearing value is less than or greater than the
30 inch pound (3.4 N.m.) value, readjust self-locking nut torque value to
produce desire result. FIGURE 35
DANGER
• Wear safety eyewear and other safety apparel appropriate
for the job application and/or job site environment.
• Bearing replacement process can create flying steel
chips and/or other debris.
• Caution all onlookers regarding the possibility of and/or
to remain clear of flying debris.
• Improper safety procedures can result in property
damage and/or personal injury.
