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 brushto 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. Ensure that the grooves for the dust seal in the swing gear and bearing are 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 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. 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.
k. Repeat Step 2.i and Step 2.j to install the entire length of the dust seal. Do not install the last
152.4 mm (6.00 inch) of the inner dust seal.
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. Make sure 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.
3. Lubricate the swing gear and bearing with grease.

Note: Clean the mating surface for the swing gear and bearing on the undercarriage frame assembly.
4. Apply Tooling (E) on the mating surface for the swing gear and bearing of the undercarriage frame
assembly.
5. Fasten Tooling (A) and a suitable lifting device to swing gear and bearing (1), as shown. Refer to
Illustration 2. The weight of swing gear and bearing (1) is 495 kg (1091 lb).
6. Place the swing gear and bearing into the original positions on the undercarriage frame assembly.

8. Apply a thin coat of Tooling (F) on the threads of bolts (2). Install the spacers and bolts (2) that
secure the swing gear and bearing to the undercarriage frame assembly.
Note: Some machines use bolts that are plated with Dacromet. Dacromet bolts appear silver, gray in
color. Do not apply Tooling (F) to the threads of Dacromet bolts. Make sure that the bolt holes are
clean and dry when Dacromet bolts are used.
9. Use Tooling (B) to tighten bolts (2) to a torque of 568 ± 59 N·m (419 ± 44 lb ft).
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.
10. Add Tooling (D) to the swing gear and bearing after the installation . Refer to Operation and
Maintenance Manual, "Swing Gear - Lubricate" and Operation and Maintenance Manual, "Swing
Bearing - Lubricate"for lubricating the swing gear and bearing.
End By:
a. Install the undercarriage frame assembly. Refer to Disassembly and Assembly, "Undercarriage
Frame - Install".
