Introduction
The 700 series Low Speed High Torque (LSHT) hydraulic motor is designed to provide
long life while operating with low radial side loads. Refer to catalog radial load limits. However, should
maintenance be required, the instructions below should be used for disassembly, replacement of parts,
cleaning and assembly.
Read the trouble shooting information to eliminate non-hydraulic causes and hydraulic system problems. The
check list identifies hydraulic system and possible motor component problems. Read all disassembly and
assembly sections carefully. Pay special attention to the notes, cautions and warnings.
The component part names and item numbers assigned on the exploded assembly views corresponds with
names and item numbers (in parentheses) used in the disassembly and assembly procedures. Refer to the
exploded assembly view page as you follow the procedures for ease in identifying and locating components.
Service part number charts display exploded view item numbers and part numbers.
Obtain service parts from the Original Equipment Manufacturer or your local Parker Distributor.
