Installation
NOTE: The hydraulic swivel weighs approximately 163 kg
(437 lb). The hydraulic, water, and electrical swivel
combined weigh approximately 183 kg (490 lb).
1. Lower the swivel into position.
Secure the hydraulic swivel to the turntable base plate
with the bushings, capscrews, and washers. Torque the
bolts, refer to Fasteners and Torque Values, page 1-13.
2. Position the retainer plate on the hydraulic swivel spool
ensuring they engage the lugs on the carrier frame.
Apply Loctite® 271 to the bolt threads. Torque the bolts,
refer to Fasteners and Torque Values, page 1-13. Bend
all the retainer tabs to make contact with the bolt heads.
Snug the four retainer plate bolts against the lugs on the
carrier frame and tighten the locking nuts.
3. If removed, install the electrical swivel. Refer to
Electrical Swivel, page 6-20. Connect the swivel wiring
harness connectors to the carrier and superstructure
receptacles and the yellow ground wire to the weld stud
on the carrier and superstructure frame. Secure ground
wire with washer, lockwasher and nut.
4. Install the clamp, lockwasher, flat washer and hex head
bolt to the bottom of the swivel retainer plate securing
the wiring harness.
5. Connect the hydraulic lines and water lines to the spool
of the hydraulic swivel as tagged during removal.
6. Connect the hydraulic lines to the hydraulic swivel case
as tagged during removal.
7. Connect the water lines to the water swivel case as
tagged during removal.
8. Remove the blocking material from the lift cylinder.
9. Activate all systems; cycle all functions and observe for
proper operation and any leakage.
INTEGRAL W/HYDRAULIC WATER SWIVEL
Description
The integral w/hydraulic 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 5 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.
