- 8 -
8. (A puller will be required to do this step) Remove
snap rings (#7) from both exciter shafts (#16 & #18)
and remove inner races.
9. Remove both snap ring (#1) securing bearings (#5) in
cover (#9). Remove 4 bolts and washers (#17 &
#20).
10. Support cover (#9) and use a brass punch to tap out
bearings (#5) alternate from side to side of each
bearing to eliminate binding of the bearing.
Exciter Assembly
Refer to Exciter Assembly, page 12.
1. Press inner race of bearing (#5) onto exciter shaft
(#16) and install snap ring (#7). Repeat procedure on
second exciter shaft.
2. Press remaining portion of bearing (#5) into cover
(#9) and install snap ring (#1). Repeat procedure on
second bearing.
3. Press both bearings (#6) into housing (#8) and install
snap rings (#1).
4. Supporting inner race of bearing (#6) that is already
in housing (#8), press exciter shaft (#16) into the
bearing, repeat procedure on second exciter shaft. If
the inner race of the bearing (#6) is not supported
properly, the bearing can be damaged.
5. Apply GasketMaker type sealant onto gearbox
housing (#8). Make sure all 4 dowel pins (#14) are in
place and install cover (#9). Secure cover with bolts
(#23) and torque to 23 ft/lbs. Check and see that both
shafts rotate freely.
6. With the exciter housing sitting as shown, both
exciters shafts should be in a position with the heavy
side down. Install gears (#11 & #12) over the shafts
without rotating the shafts and install snap rings (#2).
See figure 3 for proper timing.
7. Install gasket (#13) and cover (#10) onto housing
(#8). Ensure dowel pins (#4) are in place, secure
cover with bolts (#23), and torque to 23 ft/lbs.
8. Apply GasketMaker type sealant and install motor
(#15). Secure with socket head cap screws and lock
washer (#21, #22, & #25).
9. Install plugs (#19) and fill with 17oz of exciter oil,
install fill plug (#24).
Vibration Head Assembly
Refer to Vibration Head Assembly, page 16.
1. Loosely assemble fittings (#2) to motor on exciter as
shown.
2. Place shims in proper locations, and set exciter in
place. If using a new exciter or new vibration head
weldment, use shims to ensure exciter sits flat in
weldment. No “rocking” should be noticeable.
3. Bolt exciter into place with nuts (#22), lock washers
(#20), and washers (#21). Torque to 315 ft-lbs.
4. Assemble fittings (#3 & #1) to valve block (#13) as
shown. Tighten fully.
5. Install motor supply hose (#6) from the fitting on the
valve block closest to the exciter, to the fitting on the
motor closest to the side of the weldment (#15).
Route hose so that it will not chafe or become
pinched. Tighten hose and the motor fitting.
6. Install second hose (#5) from the fitting on the valve
block farthest from the exciter, to the fitting on the
motor closest the center of the unit. Route the hose
so that it will not chafe or become pinched. Tighten
hose and the motor fitting.
7. Install main supply lines (#9 & #12) so that they will
not chafe against the weldment (#15).
Wheel Disassembly
Refer to Wheel Assembly, page 18.
1. Remove unit from excavator, support blade with
blocks and chock the wheel so that unit is secure,
stable, and upright.
2. Wash the drum and lower frame to remove all dirt,
grime and sand that could contaminate the bearings.
3. Secure an adequate lifting device to the mounting
bracket and lift the unit just enough to lift the wheel off
the ground.
