NOTICE
Improper installation may cause moisture and
contaminants to enter the gear, which may result
in severe damage.
12. Install the new bellows on the gear. Ensure the
bellows are seated properly on the gear housing
and inner tie rods.
13. Rotate the bellows back and forth approximately
15 degrees to evenly disperse the sealant be-
tween the bellows and the gear housing.
14. Install new Oetiker clamps on each of the bel-
lows as follows.
NOTICE
Fully opening an Oetiker clamp may cause perma-
nent damage and render it ineffective.
14.1
Rotate the ears of the large Oetiker
clamp forward on the bellows to avoid
pinching the clamp in the next step.
14.2
Ensure the large Oetiker clamp is prop-
erly seated in the clamp groove on the
bellows. Align the large Oetiker clamp ear
with the small clamp ear. Both clamp ears
should be aligned with the rack housing
casting rib. See
Fig. 7
.
NOTICE
Do not over-tighten the Oetiker clamps. Over-
tightening may lead to stretching of the clamp,
which could allow moisture intrusion and corro-
sion. If an Oetiker clamp stretches, remove and
discard the clamp and install a new clamp.
All three barbs on the clamp must be engaged. If
all three barbs are not engaged after crimping, re-
move and discard the clamp and install a new
clamp. Oetiker clamps must be adequately
crimped and the bellows must be tightly secured
to the gear housing to prevent moisture intrusion
and corrosion.
14.3
Using an Oetiker clamp tool like the one
shown in
Fig. 8
, crimp the small and
large Oetiker bellows clamp ears until the
ear width is 0.08 to 0.16 in (2 to 4 mm).
See
Fig. 9
and
Fig. 10
.
15. Remove excess grease from the bellows and the
gear housing.

Evenly apply a bead of Terostat MS 939 sealant where the
large ends of the bellows seat on the gear housing.
