ReferenceRefer to Testing and Adjusting, "Relief Valve (Steering) - Test and Adjust" for the pressure setting of the relief valve.

ReferenceRefer to Testing and Adjusting, "Valve Stem in Center Position for Steering Control Valve - Test and Adjust" for the pressure to the steering cylinders.

ReferenceRefer to Testing and Adjusting, "Valve Stem in Center Position for Steering Control Valve - Test and Adjust" for the allowable difference in pressures between the steering cylinders.

Maximum opening pressure of flow control valve ... 1400 kPa (200 psi)

(1) Port for hydraulic tank

(2) Outlet port to the steering cylinders for a right turn

(3) Outlet port to the steering cylinders for a left turn

(4) Torque for nut ... 18 ± 2 N·m (13 ± 2 lb ft)

Note: Hold retainer assembly (19) when you are tightening nut (4) .

(5) Inlet port for the hydraulic and steering pump

(6) Lubricate the seal with a thin covering of the lubricant that is being sealed.
