SWING SYSTEM RT9130E-2 SERVICE MANUAL
SWIVELS
Description
The swivel assembly consists of a 11 port hydraulic swivel, a
2 port water swivel, and a 20 conductor slip ring electrical
swivel (Figure 6-5). Solid connections cannot be used to
transfer oil, heater hot water and electricity between the
carrier and superstructure due to the continuous 360 degree
swing. The use of swivels efficiently accomplishes this
function.
The barrel portion of the hydraulic swivel is attached to the
turntable base plate by four bolts, washers and bushings,
which connect to mounting lugs on the case. The spool
portion of the swivel rides upon a thrust ring at the top of the
swivel case. The spool portion is held stationary with the
carrier by bolts, and bolt retainer plates attached to the
swivel retainer plate which engages the carrier frame lugs
with bolts and jam nuts. This allows the spool to remain
stationary with the carrier as the case rotates with the
superstructure.
The spool portion of the water swivel is attached to the spool
of the hydraulic swivel by four bolts. The hydraulic and water
swivel spools remain stationary with the carrier as the
superstructure rotates. The water swivel case contains a lug
which is keyed to a corresponding lug on the hydraulic swivel
case, causing the water swivel to rotate with the
superstructure.
The electrical swivel center or collector ring assembly is
secured by setscrews to a center post which is bolted to the
spool of the hydraulic swivel. This allows the collector ring
assembly to remain stationary with the carrier. The outer
portion or brush assembly is mounted on two studs which
are located on the mounting plate assembly which is
retained to the water swivel barrel by a bolt. This allows the
brush assembly to rotate with the superstructure around the
stationary collector core.
