Front Axle - Adjust Steering Stop (on 6140M Tractor)

IMPORTANT:

LX1053443-UN-23MAY12

IMPORTANT: If equipped, fenders may deflect against main frame, grille screen or hood during full turn and simultaneous axle oscillation.

A narrower turn radius may be obtained by utilizing a shorter stop position.

1. Adjust fenders (if equipped) and tread settings before setting steering stop positions.

2. Select the correct steering stop position for the tire size and tread width. See tables below.

3. Measure the length of screw (a) as shown; this will bring the steering stops to their correct position.

4. Tighten the steering stop retaining nuts to the specified torque.

   Item	Measurement	Specification
   Steering Stop Retaining Nuts	Torque	250 N·m (185 lb.-ft.)

5. Turn wheel fully to the right. Impact the knuckle housing against the steering stop five times. Repeat on the left side.

6. Tighten the steering stop retaining nuts to the specified torque once again.

7. Turn steering wheel fully to the left and then fully to the right to check clearance.

   IMPORTANT: Settings listed are approximate, due to variations in tire size. Steering stops are adjusted properly if the tires leave 20 mm (0.79 in.) clearance with regard to the frame and side of the tractor when the axle is oscillated to its full extent.
