Testing the internal decompression valve
Notice!
The internal decompression valve releases hydraulic oil at 210 – 230 bar (3046 –
3336 psi) around the internal piston tube body of the PowerTilt swivel device.
☞
Connect a 350 bar (5076 psi) pressure gauge to the hydraulic line to
P1
. Create
pressure until the shaft reaches the bottom dead centre externally, i. e. until the shaft
bracket or the base block on the drive-shaft side touches the housing or the bracket.
☞
Remove the hydraulic hose from port
P2
and close it (port side to excavator).
☞
Connect the other hydraulic hose to
P2
temporarily and place the open end of the hose
in a container.
Notice!
The internal decompression valve is set at the factory and cannot be adjusted.
☞
Slowly create the pressure at
P1
. Check the pressure value at which oil escapes at
P2
.
Oil escapes at 210 – 230 bar
(3046 – 3336 psi)
.
☞
Check
P2
in the same way.
☞
Replace the valve if the test pressure does not correspond to the specifications.
