OVERVIEW
This section describes the removal, inspection, and reinstallation (as
required for maintenance and repair) of the Hale pump and gearbox compo-
nents. Follow the disassembly instructions in the order in which they
appear in this section. At any point in the disassembly process, the unit can
be reassembled by following the instructions in the reverse.

or your authorized Hale Products service representative. Be sure you have
sufficient knowledge, experience and the proper tools.
Wherever there is a requirement for new parts, it is recommended to use
only Hale authorized replacement parts for optimum safety of the equip-
ment and its operators and to limit "downtime."
