This Service and Repair Manual is designed
to provide information useful in servicing and

series motor.
Also included is a glossary of terms that are
frequently used throughout the industry and in
Hydro-Gear service publications. Understand-
ing terminology is very important!
It is necessary, and a good shop practice, that
your service area be equipped with the proper
tools and the mechanics be supplied the latest
information available. All repair procedures
illustrated in this guide are suggested, but pre-
ferred methods of repair.
Internal repair procedures require that the
HGM-H series motor be removed from the
vehicle.
This is not a certication, test or study guide for
a certication test. If a technician is interested
in certication, they should contact an agent
representing the EETC (Equipment and Engine
Training Council) at [phone] or their
Hydro-Gear Central Service Distributor. Many
distributors will be hosting certication testing.
These study guides will cover most of the prod-
ucts and manufacturers in our industry.
