4.4-2 Sideshift Circuit Test
1 Press the solenoid button (if equipped) and listen for a
'click' at the solenoid valve. If no sound is heard, first
check the fuse, wiring and coil (see Section 4.5). Then
assure that the valve is not jammed (see Section 5.5).
IMPORTANT: Solenoid-operated valves must be
plumbed so that the solenoid is not energized during
the SIDESHIFT function.
2 Position the arms to mid-stroke. Turn the truck off and
connect a 3500 psi (240 bar) pressure gauge to the
TEST port on the main valve.
3 With a maximum load, sideshift left and hold the lever
for a few seconds.
4 Release the lever and watch the pressure gauge:
• If the arms sideshift slowly or not at all, the SIDE-
SHIFT relief cartridge may be faulty. Replace the
cartridge.
• If the pressure drop is more than 150 psi (10 bar)
initially, and additional drop exceeds 25 psi (2 bar)
per minute, the SIDESHIFT LEFT check valve
cartridge may be faulty. Replace the cartridge.
• If the pressure drop is less than above, sideshift
right and hold the lever for a few seconds.
5 Release the lever and watch the pressure gauge:
• If the pressure drop is more than 150 psi (10 bar)
initially, and additional drop exceeds 25 psi (2 bar)
per minute, the SIDESHIFT RIGHT check valve
cartridge may be faulty. Replace the cartridge.
• If the pressure drop is less than 150 psi (10 bar)
initially, and additional drop does not exceed 25 psi
(1.7 bar) per minute, the problem is not hydraulic
(see Section 4.1-3).
