and activates the piston rod (5). The piston rod (5) is connected with the steering arm (6) which moves the steering roll to
the left or to the right.
(2) Disconnect the hydraulic lines from the cylinder (3).
(3) Remove the cotter pin and drive out the pin connecting the cylinder swivel head (2) with the mounting
(4) Remove the cotter pin and drive out the piston rod pin (7) connecting the piston rod (5) with the steering arm
(5) Remove the hydraulic steering cylinder (3).
c. Inspection. Inspect the hydraulic steering cylinder for loose stud nuts, corrosion, dents, and cracks. Inspect the
cylinder gland for leaks. Check the piston rod and piston pins for corrosion, pitting, and excessive wear. Discard used
cotter pins. Always use new cotter pins when reassembling and installing the steering cylinder.
(1) Install the steering cylinder in its proper mounting place and connect the cylinder swivel head (2) with the
mounting bracket (1). Install the pin and secure it with the cotter pin.
(2) Connect the piston rod (5) with the steering arm (6).
(3) Install the piston rod pin (7) and secure it with the cotter pin.
(4) Connect the hydraulic oil lines with the adapter elbows on the steering cylinder elbow nuts securely.
(6) Operate the roller and check the steering cylinder for leaks and proper operation.
a. General. The steering cylinder packing is of the split-collar type and can be installed on the piston rod (8) without
removing the rod from the steering cylinder (2). Packing is retained in its place by the gland (7) which is attached to the
cylinder gland seat head (4) by two gland screws (6).
(1) Remove the gland mounting screws (6).
(2) Push the gland (7) back along the piston rod (8).
(3) Use a blunt screwdriver to remove the packings from their seat. Discard gritty, damaged, worn, frayed, or
(1) Place the packing around the piston rod (8). Place each section separately.
