Service Manual

FOREWORD
This service and repair manual has been compiled to provide
authorized Wheel Horse service personnel with proper procedures and
techniques for servicing hydraulic
lift control valves and cylinders
used on Wheel Horse equipment.
Following Table of Contents
lists all areas covered. It is adviseable
to read all sections first to become familiar with repair procedures.
Since valves and cylinders are hydraulic components, strict clean-
liness must be maintained during all stages of service and repair.
Even a small amount of
dirt or contamination can severely damage
components. Always use clean solvent when cleaning parts.
If con-
tamination
of hydraulic system has occurred or is suspected, be sure to
clean entire system. Clean
lift cylinder, valve, all hoses and lines.
Transmission and transaxle must be cleaned to insure all contaminants
are removed.
