Wheel End Seal
Four-piece Tang/Dowel-type Lock Washer System
a. Install the Dowel-type lock washer on the spindle.
Note: If the dowel pin and washer are not aligned, remove
washer, turn it over and reinstall. If required, loosen
the inner nut just enough for alignment.
CAUTION:
Never tighten the inner nut for alignment. This can preload
the bearing and cause premature failure.
b. Install the Tang-type lock washer on the spindle.
c. Install the outer nut on the spindle and tighten to
250 lb-ft. (339 N•m).
d. Verify endplay.
e. After verifying endplay, secure the outer nut by
bending (180° apart) two opposing tangs of the
locking washer over the outer nut.
15. Install the following:
•
New gasket at axle shaft flange
• Axle shaft
• Axle flange nuts and tighten to specified torque
16. Lubricate axle wheel ends.
Replace Seal
Spicer strongly recommends using seal drivers when installing
new seals. Use the proper driver to make sure that the seal is
square and installed to the proper depth.
CAUTION:
Oil seals can be easily damaged prior to installation. Use
care when handling the new seal to prevent damage or con-
tamination. Leave the seal in its package until installation.
On new yokes, leave the protector on the yoke until it is
installed on the shaft to prevent damage or contamination.
17. Remove the old yoke using appropriate tool. A yoke
puller tool may be made from the center section of
most gear puller tools, or may be purchased from
your local tool distributor.
18. Remove seal. Use care when removing the old seal
to prevent damage to the housing seal bore.
19. Inspect the seal bore area for any damage (nicks,
gouges, corrosion). Carefully remove any slight
damage with a crocus cloth. Clean the bore area to
remove any loose debris.
CAUTION:
Do not use any silicone or permatex-type bore sealant with
this seal.
