Wear block adjustment
All of the steering gear boxes have a wear block
that presses the wear block against the steering rack to
set the back lash between the steering rack and the
input shaft. Most of the steering gear boxes have a
spring that holds a constant pressure on the wear
block.
On some of the 618-04430 steering gear boxes,
there is an adjustment bolt for the wear block. To adjust
the bolt:
NOTE: This procedure can be performed while
the steering gear box is installed in the tractor.
1. If the steering gear box is installed in the tractor,
isolate it by disconnecting both of the steering
links. See Figure 6A.75.
2. Loosen the jam nut on the adjustment bolt using
a 9/16” wrench. See Figure 6A.76.

3. While turning the input shaft, tighten the adjust-
ment bolt until increased drag is felt.
See Figure 6A.77.
4. Back the bolt off a quarter to a half turn.
5. While holding the adjustment bolt with one
wrench, tighten the jam nut to lock it in place.
6. Check the steering gearbox by turning it through
its full range of motion. Drag should be consis-
tent through the complete range.
7. Install the gear box in the tractor or attach the
steering links if it was already installed.
8. Test drive the tractor in a safe area before
returning to service.
