Loosen and remove the two hose clamps
securing the suction hose, 1, to the suction
screen port. Remove the suction hose. Unscrew
the suction screen, 2, from the top of the
hydraulic tank and remove it. Cover the hole in
the tank so contaminants cannot enter.
The suction screen can be washed in a cleaning
solvent to remove any debris accumulated in it.
Reinstall the suction screen into the top of the
tank and tighten securely. Reinstall the suction
hose onto the steering pump and suction screen
and tighten the hose clamps to ensure that no air
can enter the hydraulic system.
