Mechanical System Maintenance
8.1 General
This chapter covers the maintenance and repair of
all non-breathing system components of the Kirby
Morgan 37SS Diver’s Helmet. Correct repairs will
result in better communications and improved over-
all diver comfort and performance in getting the job
done. Numbers appearing in parentheses below are
“location” numbers that are used in the blowapart
drawing at the rear of this manual.
All the spare parts in our catalog were specifically
manufactured (or inspected and tested) for Kirby
Morgan designed helmets and masks. When ordering
spares, insist on KMDSI original parts.

WARNING
Use only KMDSI original replacement
spares when repairing your helmet.
The use of other manufacturer’s parts
will interfere with the performance
characteristics of your life support
equipment and may jeopardize your
safety. Additionally, any substitutions
will void all warranties offered by
KMDSI.
B
WARNING
All parts on Kirby Morgan masks and
helmets must be adjusted to their
proper torque specifications. See
Appendix 1 for a complete listing of
torque specifications for each part.
Failure to adjust parts to the recom-
mended specifications could lead to
helmet failure and accidents. This
could be fatal.
NOTE: For o-ring Removal/Inspection/Cleaning
& Installation see Chapter 6. For General Clean-
ing Guidelines, including KMDSI recommended
cleaning, sanitizing solutions, and procedures, see
Chapter 6.
8.2 Helmet Shell Inspection
The helmet shell is constructed using 316L stainless
steel. It is extremely durable but can be damaged.
Helmets that have suffered damage may be repair-
able, but repairs to the helmet shell must only be
accomplished by KMDSI technicians that have been
trained and certified by KMDSI.
B
WARNING
Do not attempt to re-thread the hel-
met shell for the port retainer screws
by yourself. If the installation is done
improperly, the port retainer can come
loose and the helmet could flood
resulting in drowning. Repairs should
be only be completed by technicians
specifically trained and certified in
these procedures.
1) Visually inspect the helmet shell exterior for ob-
vious signs of damage including cracks, gouges or
depressions.
NOTE: The helmet should not be used if it has any
gouges deeper than
1/16
inch. Repairs should only
be completed by a KMDSI trained and certified
repair technician that has received certification for
helmet shell repairs by KMDSI or Dive Lab Inc.
Any signs of cracks or depressions with fractures or
other damage should be checked by an authorized
KMDSI repair facility or a technician certified by
KMDSI in specialized stainless steel repair.
