Steering System 197 Service Manual – SC8000
Troubleshooting
Problem Cause Correction
The steering
“wanders”.
Backlash in the spur gear
and rack
Adjust the rack so it’s closer to the spur gear.
The steering is hard
or “jerky”.
Not enough oil to the
steering system
Clean or replace the priority flow divider cartridge on
the accessory/auxiliary pump.
Removal and Installation
Warning! Before removing or reinstalling any machine components, make sure the key switch
is off, the key is removed from the machine and the parking brake is engaged.
Note: If the steer cylinder is removed, mark the teeth where the rack engages the spur gear so the
rack and spur gear engage at the same location when the steer cylinder is reinstalled.
