Usage:
1. Disconnect oil lines (4) from the steering cylinder.
2. Remove bolt (2). Remove pin (1) that holds the cylinder to the front axle.
3. Fasten a hoist to the cylinder.
4. Remove the cotter pin from nut (3) and the pin. Loosen nut (3). Loosen the pin from its taper. Remove nut (3).
5. Remove steering cylinder (5). The weight of the steering cylinder is 19 Kg (42 lbs.).
NOTE: The following steps are for installation of the steering cylinders
6. Fasten a hoist to the steering cylinder. Put steering cylinder (5) in position on the front axle and the wheel spindle housing. Install the pin (1) that holds the cylinder (5) to the front axle. Install the bolt (2) that holds the pin.
7. Install nut (3) on the pin. Tighten the nut to a torque of 140 ± 14 N·m (105 ± 10 lb.ft.). Always tighten the nut (3) to put the cotter groove (slot) in alignment with the hole in the pin. Remove the hoist.
8. Connect oil lines (4) to their correct locations on the cylinder (5).
9. Fill the hydraulic tank with oil to its correct level. See the Maintenance Manual.
10. The following procedure must be used to make a toe-in adjustment for the front wheels.
a. Lift front wheels off ground. Install lockpin in tie bar of wheel lean.
b. Rotate the wheel to put a mark around the center of the tread on each tire.
c. Measure the distance from the mark on one tire to the mark on the other tire at both the front and at the rear of the tires. Toe-in is correct when measurement at the front tires is 3.0 to 6.3 mm (.12 to .25 in.) less than the measurement at the rear of the tires.
d. Make the toe-in adjustment if needed. Loosen nut (7) and the nut in the clamp in the other side of tie rod (6). Rotate tie rod (6) in the direction needed to get the correct toe-in for the front wheels. When the toe-in adjustment is correct, tighten the nuts (7) in the clamps on tie rod (6).
Adjustment For The Lengths Of The Rods In The Steering Cylinders When The Toe-In For The Front Wheels Is Correct:
a. Lift front wheels off ground. Install lock pin in tie bar.
b. Loosen locknut (9) and turn cylinder rod (8) on the threads of the ball socket (10) as far as possible. Do the same with the cylinder rod and ball socket on the right side.
c. Steer the wheels for a maximum turn to the left and hold the steering wheel in that position.
NOTE: During the next step, it will be necessary to turn the steering wheel back enough to release hydraulic pressure, but be sure the steering system is turned to the maximum when adjustment checks are made.
d. Turn the right hand cylinder rod to extend the socket until the stop on the left spindle housing (12) is in contact with left hand stop (11) on the axle (grind the stop surfaces if necessary to give maximum contact area), then turn the cylinder rod six more complete turns [10.9 mm (.43 in.)], and tighten locknuts (9) 340 ± 40 N·m (250 ± 30 lb.ft.).
e. Turn the steering wheel to move the front wheels to a position of maximum right turn, and hold the steering wheel in this position.
NOTE: During the next step, it will be necessary to turn the steering wheel back enough to release hydraulic pressure, but be sure the steering system is turned to the maximum when adjustment checks are made.
f. Turn the left hand cylinder rod to extend the socket until the stop on the right spinde housing is in contact with the right hand stop on the axle (grind the stop surfaces if necessary to give maximum contact area), then turn the cylinder rod six more complete turns [10.9 mm (.43 in.)], and tighten locknut (9) to 340 ± 40 N·m (250 ± 30 lb.ft.).
