12 HYDRAULIC MOTOR DISASSEMBLY:
Note: Cleanliness of the maintenance work area should
be maintained whenever performing any work on the
tool. Due to the exacting nature of the tolerances in a hy-
draulic motor, extra vigilance must be observed. Even
a small amount of foreign matter can cause immediate
failure, or seriously degrade the motor’s performance
and shorten its life. Inspect all parts for dirt or dust prior
to installation and keep them covered with a lint--free
cloth when not working on them.
Note: Never place the motor or any of its components in
a vise. Deformation will occur.
