TRACTOR WHEEL ASSEMBLIES, BEARINGS AND SEALS
14.Use tool (D) and fasten a hoist to the hub assembly and
gear. Put the hub assembly and gear in position on the
machine.
15.Install the nut on the spindle.
16. Tighten the nut with tool (E) while the wheel is turned with a
8 in.(203 mm) long Ib.in.(N m) 9S7354 torque wrench.
The torque must be 75 25 lb.in.(8.50 2.83 N-m).For
other lb.in. torque wrenches, the correct torque indication
can be found with this formula:
C= A x T
A + B
"C" is the torque wrench reading.
"A" is the length of the torque wrench.
"B" is the distance from the center of the wheel to the wheel
stud.
"T" is torque on bearings IT = 160 + 50 Ib.in.(18.1 5.7 N
m)].
NOTE: The torque wrench must be installed on wheel nut so it
is in line with the center of the wheel as shown.
17. Turn wheel slowly at a constant speed for one or two turns
to check torque reading after adjustment has been made.
18 .Install lock (7) on the nut. Tighten the nut more if needed
to get the lock in alignment with bolt holes. Install the
bolts and lock wire.
