Steering Tie Rod

Usage:

Remove And Install Steering Tie Rod

1. Remove the cotter pins from the pins at each end of the tie rod. Loosen nuts (3) and (5) until they are even with the bottom of the pins.

2. Hit the nuts with a hammer to break the pins loose from their tapers. Remove nuts (3) and (5).

3. Remove steering tie rod (4).

NOTE: The following steps are for installation of the steering tie rod.

4. Put steering tie rod (4) in position on the wheel spindle housing. Install the nuts (3) and (5) on the pins. Tighten the nuts to a torque of 120 N·m (90 lb.ft.), plus the torque required to align the cotter slot. Install the cotter pins.

5. The following procedure must be used to make a toe-in adjustment to the front wheels:

a. Lift the front wheels off the ground. Install the lock pin in the wheel lean bar and the front axle.

b. Turn the wheels to put a mark on the center of the tread of the tires.

c. Measure the distance from the mark on one tire to the mark on the other tire. Toe-in is correct when the measurement at the front of the tire is 3.0 to 6.3 mm (.12 to .25 in.) less than the measurement at the rear of the tires.

d. Make a toe-in adjustment if needed. Loosen nuts (1) and (2). Turn tie rod (4) in direction needed to get the correct toe-in for the front wheels. Tighten nut (1) and (2) to a torque of 75 ± 7 N·m (55 ± 5 lb.ft.).
