Steering System
1. General Information
The steering is cable and chain operated and power assisted
through the use of a hydraulic torque generator. Because of
the complexity of the steering linkage, if any adjustments are
required, the entire adjusting procedure must be followed.
1. Adjust transmission steering ring guide rollers
snug, but not tight, against the guide ring (+0.0156
in. ; -0.0 in.).
Guide rollers are mounted on eccentric pins.
Loosen bolts and turn cam on eccentric. Be sure to
tighten nuts and bolts.
2. Adjust steering chain around transmission and
bottom sprocket of torque generator.
Loosen two 3/8 in. NC bolts that lock chain ends to
transmission case. Turn adjusting turnbuckle to
tighten chain so that it has 1/8 in. to 1/4 in. of slack
on one side. Tighten locking bolts.
3. Adjust upper chain around torque generator and
jackshaft.
Jackshaft mounting bracket is on a pivot. Loosen
locknuts on stud and pivot mounting bracket to
adjust chain for 1/8 in. to 1/4 in. of slack on one
side. Tighten lock nuts.
4. Adjust steering cable in mast.
Raise platform and block securely so that cable
tension springs and turn buckles are visible. Both
turn buckles must be adjusted an equal amount so
that the steering remains centered.
Adjust turn buckles so that tension springs are
collapsed all but one full coil.
