The main components of the hydraulic cylinder are shown in the figure above. While the lift arm (11) is rising, oil from the hydraulic pump flows into the hydraulic cylinder (4) through the position control valve (14). Then oil pushes the hydraulic piston (7) out. While the lift arm (11) is lowering, oil in the… Read More »
1. When the engine is started, the hydraulic pump (3) is rotated to draw oil from the transmission case (1) through the suction pipe. Supplied oil is filtered by the hydraulic oil filter (2). 2. Filtered oil is forced out by the hydraulic pump to the position control valve (5) through the delivery pipe. 3.… Read More »

1. Set a dial indicator with its finger on the worm shaft of the ball nut assembly. 2. Move the worm shaft axially and measure the play. 3. If the play exceeds the allowable limit, replace the steering gear box assembly. NOTE • Check ball nut assembly for smooth rotation by holding the ball nut… Read More »
1. Measure the gear box cylinder I.D. with a cylinder gauge. 2. Measure the ball nut O.D. with an outside micrometer. 3. If the clearance exceeds the factory specifications, replace the steering gear box assembly.
1. Measure the sleeve O.D. with an outside micrometer. 2. Measure the valve housing I.D. with a caliper gauge. 3. If the clearance exceeds the allowable limit, replace the steering gear box assembly.
1. Set a dial indicator with its finger on the pitman arm. 2. Move the pitman arm lightly, and measure the pitman arm deflection. 3. If the measurement is not within the factory specifications, adjust the backlash with the adjusting screw.
