Service

Complete disassembly of the power unit is not neces-
sary or recommended. Any service requirements that
need to be addressed with the engine or its components
will be covered in the engine manufacturer's Owner's
Manual.
It is anticipated that only two other items could require
servicing on this unit—the hydraulic pump and the relief
valve. This section will cover the removal and replace-
ment of these items.
Relief Valve
If the system relief pressure settings cannot be adjusted
to obtain the maximum system pressure as identified in
Specifications, the relief valve (80) needs to be removed
from the manifold block (83), and replaced.
