5. Install brake assembly, brake drum assembly and
front wheel to machine (see Front Wheel and Brake in
the Service and Repairs section of Chapter 6 -- Chas-
sis).
Failure t o maintain proper wheel lug nut and
wheel hub lock nut torque could result in failure
orlossof wheeland mayresultin personalinjury.
WARNING
6. Make sure to properly torque lock nut from 250 to
400 ft--lb (339 to 540 N--m) and wheel lug nuts from 70
to 90 ft--lb (95 to 122 N--m).
