of cylinder

Steering unit (OSPF)
Start the engine and run until oil is at normal
operating temperature and any air is purged from
system. Set engine at maximum rev/min, turn the
steering wheel until the steering stops make
contact. If the steering wheel can be turned without
significant effort or the wheel turns on it’s own, the
rotor, spool or shock valves are faulty and the
steering unit must be replaced.
Servicing
Servicing is normally limited to the replacement of
the three main components (steering unit, adapter
and steering valve) and the seals between these
components.
The steering cylinders can also be overhauled. For
overhaul of the steering cylinder, refer to the
Hydraulic Manual.
