RT9130E SERVICE MANUAL SWING SYSTEM
10. Position an adequate supporting device beneath the
swivel.
11. Remove the four capscrews, washers, and bushings
securing the swivel barrel to the turntable base plate and
lower the swivel to the ground.
Installation
NOTE: The hydraulic swivel weighs approximately 195 kg
(430 lb). The hydraulic, water, and electrical swivel
combined weigh approximately 236 kg (520
pounds).
1. Raise the swivel into position.
2. Secure the hydraulic swivel to the turntable base plate
with the bushings, capscrews, and washers. Torque the
bolts to 760 to 814 Nm (560 to 600 foot-pounds).
3. Position the two retainer plates on the hydraulic swivel
spool ensuring they engage the lugs on the carrier
frame. Secure the retainer plates with eight capscrews
and four capscrew retainers.
Apply Loctite 271 to the capscrew threads. Torque the
capscrews to 122 Nm (90 foot-pounds). Bend all the
retainer tabs to make contact with the capscrew heads.
Sung the four retainer plate capscrews against the lugs
on the carrier frame and tighten the locking nuts.
4. If removed, install the electrical swivel. Refer to
ELECTRICAL SWIVEL in this Section. Connect the
swivel wiring harness connectors to the carrier
receptacles and the yellow ground wire to the mounting
bracket on the carrier frame. Use the bolt and star
washers taken off at removal and refer to Grove
Engineering Specification A-829-100386 for proper
electrical termination of grounds.
5. Install the clamp, lockwasher, flat washer and capscrew
to the bottom of the swivel retainer plate securing the
wiring harness.
6. Connect the hydraulic lines and water lines to the spool
of the hydraulic swivel as tagged during removal.
7. Connect the hydraulic lines to the hydraulic swivel case
as tagged during removal.
8. Connect the water lines to the water swivel case as
tagged during removal.
9. Remove the blocking material from the lift cylinder.
10. Activate all systems; cycle all functions and observe for
proper operation and any leakage.
Two-Port Water Swivel
Description
The two-port water swivel allows engine coolant to flow from
the carrier-mounted engine to the hot water heater in the
operator’s cab. Through an internally drilled passage in the
11 port hydraulic swivel spool, coolant is transferred to a
circumferential groove on the water spool exterior. This
groove corresponds with a mating port on the outer case of
the water swivel. The spool grooves are separated by a quad
ring/telflon bronze ring seal. The lip seal prevents coolant
from leaking externally. Return engine coolant flow from the
hot water heater is accomplished in the same manner
through the opposite port of the water swivel.
Maintenance
Removal
1. Perform steps 1 thru 4 of HYDRAULIC SWIVEL -
REMOVAL in this section.
2. Remove the electrical swivel. Refer to ELECTRICAL
SWIVEL - REMOVAL in this section.
3. Tag and disconnect the lines from the case of the water
swivel. Cap or plug all lines and openings.
4. Remove the bolt and shim(s) from the water/hydraulic
swivel keying lugs.
5. Remove the four capscrews and washers securing the
water swivel and electrical swivel center post to the
hydraulic swivel. Remove the water swivel and center
post.
Disassembly
NOTE: Any maintenance requiring disassembly of the
water swivel should include replacement of all
seals and rings.
1. Withdraw the spool from the case.
2. Place the spool on a clean work surface in a dust-free
area and block the spool to prevent movement during
disassembly.
NOTE: Aligning discarded seals and rings in the order of
disassembly will assist with installation of new
seals and rings.
3. Remove the seals and rings from the spool.
CAUTION
When removing seals and rings, avoid scratching
grooved and gland surfaces.
