reinstall plug in frame.
5. If machine is equipped with optional 3WD kit, install
rear wheel motor to rear steering fork (see R ear Wheel
Motor(Optional3WD)InstallationintheServiceandRe-
pairs section of Chapter 5 -- Hydraulic System).
6. If wheel spindle assembly was removed from rear
steering fork, secure spindle assembly to steering fork.
Cut--outs in wheel hub will allow access to cap screws
that secure spindle assembly to steering fork.
7. Insert the steering cylinder rod end into the rear
steering fork.
8. Secure steeringcylinderto steeringforkwith two(2)

60to 80ft--lb (82to108 N--m).Then,while holdingfirst
jam nutwith wrench, tightensecond jamnut and torque
from 60 to 80 ft--lb (82 to 108 N--m) .
9. Install rear wheel assembly (see Wheel Installation
in this section).
Failure to maintain proper wheel lug nut torque
couldresultinfailure orlossofwheeland mayre-
sult in personal injury.
WARNING
