TMS700E SERVICE MANUAL SWING SYSTEM
TWO PORT WATER SWIVEL
Description
The 2 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 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.
Maintenance
Removal
1. Perform steps 1 thru 4 of Hydraulic Swivel, page 6-15,
Removal in this section.
2. Remove the electrical swivel. Refer to Electrical Swivel,
page 6-18, 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 bolts 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.
Cleaning and Inspection
1. Clean the spool and case with a suitable solution and
dry with compressed air. Plug all ports with plastic caps.
2. Check the spool and inside of the case for scratches,
grooves, scoring, etc. If any grooves have developed
with a depth of 0.127 mm (0.005 in) the unit should be
replaced.
Assembly
NOTE: Lubricate the interior of the swivel to prevent
rusting from condensation.
1. Lubricate the spool, seals, and rings.
2. Install new seals and rings on the spool.
3. Insert the spool into the barrel.
Installation
1. Install the water swivel on top of the hydraulic swivel
aligning the keyed lug on the water swivel with the lug on
the hydraulic swivel. Secure the water swivel and the
electrical swivel center post with the four bolts and
washers.
2. Install the shim(s) on the keying lug to provide a snug fit
and secure with a bolt.
3. Connect the lines to the swivel case as tagged during
removal.
4. Install the electrical swivel. Refer to Electrical Swivel,
page 6-18, Installation in this Section.
5. Perform steps 8 and 9 of Hydraulic Swivel, page 6-15,
Installation in this Section.
6. Activate all systems, cycle all functions, and observe for
proper operation and any leakage.
CAUTION
When removing seals and rings, avoid scratching
grooved and gland surfaces.
DANGER
Cleaning solvents can be toxic, flammable, an irritant to
the skin, or give off harmful fumes. Avoid prolonged skin
contact, inhalation of vapors, or smoking. Failure to
comply can result in injury or death to personnel.
CAUTION
When installing seals and rings, avoid stretching seals or
scratching grooved or gland surfaces.
