There are five potential problems that could affect the

sideshifting function:

• Inadequate upper bearing lubrication or worn bearings.

Refer to Section 4.2

• Incorrect hydraulic pressure or flow from lift truck.

• Lower mounting hooks installed with incorrect

clearance. Refer to Section 4.1, Step 4.

• External leaks due to worn or defective cylinder seals.

Refer to Section 4.3.

• Cylinder fittings or flow restrictors plugged, incorrect

type, or not installed properly. Refer to Section 4.3.

Supply Circuit Test

Check the pressure supplied by the truck at the

carriage hose terminals. Pressure must be within

the range shown in Specifications, Section 5.1.

PRESSURE TO THE SIDESHIFTER MUST NOT

EXCEED 3500 psi (245 bar).

Check the flow volume at the carriage hose terminal.

Flow must be within the range shown in Specifications,

Section 5.1.

Fully sideshift to the left. Hold the lever in the

and cylinder rod ends.

Sideshift Circuit Test

3.3-3

Fully sideshift to the left. Turn the truck off. Relieve

the attachment system pressure. Disconnect the

SIDESHIFT RIGHT supply hose from the truck hose

terminal and route to a drain bucket. Cap the supply

fitting.

Start the truck and actuate the SIDESHIFT LEFT lever

for 5 seconds:

• If there is substantial hydraulic flow out of the drain

hose, the sideshift cylinder is faulty and requires

replacement. Refer to Section 4.3.

• If there is no hydraulic flow out of the hose, check

for plugged or incorrectly installed flow restrictor

washers and fittings. If there is still no hydraulic flow,

the problem is not hydraulic. Refer to Section 3.3.
