WARNING: Before removing any hoses
or tubes, relieve pressure in the hydraulic
system. With the truck off, open the truck
auxiliary control valve(s) several times in
both directions.
4.4 Sideshift Circuit
There are six potential problems that could affect
sideshifting operation.
• Inadequate upper bearing lubrication or worn bearings.
See sections 5.2-1 and 5.2-2.
• Lower mounting hooks installed incorrectly. See section
5.1 step 6.
• Kinked supply hoses.
• External leaks.
• Incorrect hydraulic pressure/volume from the truck.
• Worn or defective cylinder seals.
1 Check the pressure delivered by the truck. Refer to
the truck service manual. The minimum recommended
truck pressure is 2000 psi (140 bar). TRUCK
PRESSURE MUST NOT EXCEED 3500 PSI (245 BAR),
measured at the carriage hose terminal.
2 Check the flow volume at the carriage hose terminal.
The recommended flow volume is 2 GPM (7.5 L/min).
3 Sideshift completely to the left and hold the control
handle in this position for 5 seconds. Check for external
leaks at the cylinder, fittings and hoses.
4 Sideshift completely to the right and hold the control
handle in this position for 5 seconds. Check for external
leaks at the cylinder, fittings and hoses.
5 Disconnect the LH cylinder hose from the hose terminal
or internal reeving fitting. Cap the supply fitting. Place
the hose end in a bucket. Start the truck. Actuate the
sideshift left control handle for 5 seconds.
• If there is oil flow out of the hose, the cylinder seals
are defective and require service. Refer to Section
5.4-2.
• If there is no oil flow out of the hose, the problem is
not hydraulic.
6 Flow Divider Valve equipped attachments – Start
the truck. Position the forks in and out. If the forks do
not position evenly, the flow divider valve cartridge or
cylinders require service. Continue troubleshooting.
7 Position the forks completely outward. Disconnect the
opposite end of the hose connected to the flow divider
valve CL (close) port from its fitting. Cap the fitting
and place the hose end in a bucket. Actuate the truck
handle to position the forks outward.
• If oil flows out of the hose, the cylinder seals require
service. See section 5.5.
• If oil does not flow out of the hose, the flow divider
valve cartridge requires service. See section 5.3-2.
