Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned
in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts.
Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are
worn or damaged, use new parts for replacement.

1. If inner dust seal (3) and outer dust seal (4) were installed dry, use the following procedure to install
the new dust seals:
a. Use a wire brush to thoroughly clean the grooves for the dust seal of the swing gear and
bearing. Make sure that all the dirt and foreign material has been removed.
b. Wash the grooves for the dust seal in a suitable solvent that will not leave an oily residue.
c. Make sure that the grooves for the dust seal in the swing gear and bearing are thoroughly clean
and dry prior to installation of the dust seals.
d. Cut one end of inner dust seal (3) at a 90 degree angle. Use a blunt tool to install the inner dust
seal in the seal groove of the swing gear and bearing.
e. Install the seal so that the lip of the seal is facing in the direction that is shown. Refer to
Illustration 1.
f. After the inner dust seal is installed in the seal groove, measure the seal and cut the remaining
end of the inner dust seal at a 90 degree angle. Install the remaining end of the inner dust seal
in the seal groove.
g. Make sure that the inner dust seal is seated properly in the seal groove, all the way around the
swing gear and bearing. Also, make sure that there is no gap between the ends of the inner dust
seal.
h. Pull each end of the inner dust seal out of the seal groove of the swing gear and bearing
approximately 50.8 mm (2.00 inch). Apply Tooling (C) to each end of the inner dust seal to
bond the seals together.
i. Immediately reinstall the inner dust seal in the seal groove of the swing gear and bearing.
Again, make sure that the entire inner dust seal is properly seated in the seal groove of the
swing gear and bearing. No gap should exist between the ends of the inner dust seal.
j. To ensure that the lip of inner dust seal has not adhered to the top of the bearing at the seal
joint, run a dull putty knife between the lip of the seal and the bearing at the seal joint.
k. Follow the procedure in Steps 1.a through 1.j to install outer dust seal (4) in the swing gear and
bearing. Refer to Illustration 1 for proper seal orientation in the swing gear and bearing.

2. If inner dust seal (3) and outer dust seal (4) were bonded in the swing gear and bearing, use the
following procedure to install the new dust seals:
a. Thoroughly clean all the dirt and foreign material from the grooves for the dust seal in the
swing gear and bearing with a wire brush.
b. Wash the grooves for the dust seal in a suitable solvent that will not leave an oily residue.
c. Make sure that the grooves for the dust seals in the swing gear and bearing are thoroughly
clean and dry prior to installation of the dust seals.
Note: Install inner dust seal (3) and outer dust seal (4) in the swing gear and bearing in small
increments, because Tooling (C) cures very quickly.
d. Cut one end of inner dust seal (3) at a 90 degree angle.
e. Start applying Tooling (C) 50.8 mm (2.00 inch) from the cut end of the seal. Apply Tooling
(C) to the seal in 152.4 mm (6.00 inch) increments.
f. Immediately use a blunt tool to install only the bonded portion of the inner dust seal in the seal
groove of the swing gear and bearing. Make sure that the dust seal is seated properly in the
seal groove.
g. Install the seal so that the lip of the seal is facing in the direction that is shown. Refer to
Illustration 1.
h. To ensure that the inner dust seal has not adhered to the bearing, run a dull putty knife between
the lip of the seal and the bearing.
i. Apply Tooling (C) to the next 152.4 mm (6.00 inch) of the seal. Immediately use a blunt tool
to install only the bonded portion of the inner dust seal in the seal groove of the swing gear and
bearing.
j. Make sure that the inner dust seal is seated properly in the seal groove. Ensure that the inner
dust seal has not adhered to the bearing.
Note: Do not install the last 152.4 mm (6.00 inch) of the inner dust seal.
k. Repeat Steps 2.i through 2.j until the dust seal is installed.
l. Measure the inner dust seal and cut the remaining end of inner dust seal (3) at a 90 degree
angle. Install the last 152.4 mm (6.00 inch) of seal in the seal groove dry.
m. Make sure that the inner dust seal is properly seated in the seal groove and that there is no gap
between the seal ends. Carefully remove both loose ends of the inner dust seal out of the seal
groove.
n. Apply Tooling (C) to the loose ends of the seal.
o. Immediately use a blunt tool to reinstall the seal ends in the seal groove. Again, make sure that
the inner dust seal is properly seated in the seal groove, and that no gap existed between the
ends of the seal.
p. To ensure that the inner dust seal has not adhered to the top of the bearing, run a dull putty
knife around the seal.
q. Follow the procedure in Steps 2.a through 2.p to install outer dust seal (4) in the swing gear
and bearing. Refer to Illustration 1 for proper seal orientation in the swing gear and bearing.

Note: Torque for bolts (2) is 250 ± 25 N·m (184 ± 18 lb ft) and turn an additional angle of 55 ± 5
degrees on 336 excavators.
9. Use Tooling (B) to tighten bolts (2) to a torque of 900 ± 100 N·m (665 ± 75 lb ft).
10. Refer to Service Magazine , M0083843 , "An Improved Bolt Tightening Procedure for the Critical
Joints Is Now Used on all Excavators" for more detailed information.
NOTICE
Improper lubrication can cause damage to machine components.
To avoid damage, make sure that the proper amount of grease is
applied to the swing drive.
When the amount of grease in the compartment becomes too large, the
agitation loss becomes large, thereby accelerating grease deterioration.
Grease deterioration can cause damage to the pinion gear of the swing
drive and swing internal gear.
Not enough grease will result in poor gear lubrication.
11. Add Tooling (D) to the swing gear and bearing after the installation.
Reference: Refer to Operation and Maintenance Manual, "Refill Capacities" for the capacity of the
swing gear and bearing.
Reference: Refer to Operation and Maintenance Manual, "Swing Gear - Lubricate" for lubricating
the swing gear and bearing.
