BAttaching the Front Tires
1. Attach the front tires (1) (left and right) with twelve M12
nuts (2), spring washers (3) and plain washers (4).
A Be sure the inflation valve stem of each tire faces
outward.
2. Tightening torque for the M12 nuts (2), should be 79.6
to 92.0 N-m (8.1 to 9.4 kgf-m).
3. Check air pressure in the front tires.
4. Remove the front jig.
5. Recheck the tightening torque for the M12 nuts (2)
after driving the tractor 200 m (200 yards) and 10 times
of shuttle movement by 5 m (5 yards).
BAttaching the Rear Tires
1. Attach the left and right hub (1) to the rear tires with six
M14 nuts (2), spring washers (3) and plain washers (4)
each.
A If the tire side wheel is made for taper nut mounting,
use only the nut and tighten with the taper side.
A Be sure the hubs are facing in the proper direction.
2. Tightening torque for the M14 nuts (2) should be 108
to 126 N-m (11.0 to 12.8 kgf-m).
3. Hook a hoist to the tractor's 3-point hitch and lift the
tractor.
4. Pull out the crate skids from the rear.
5. Insert the rear tire assembly over the axle, to the
desired tread setting: then attach the wheel tube pin
(5) and spring pin (6) and tighten the M16 nut (7), M16
spring washer (9) and M16 bolt (8).
6. Tightening torque for the M16 nut (7) should be 124 to
147 N-m (12.6 to 15.0 kgf-m).
7. The standard position of the rim on the axle is as
shown in the figure below.
