Installation
The rigors of combat combined with extremely high temperatures have been hard
on CIP panels mounted with hook-and-pile. Some of those panels have fallen off
and been lost.
To keep those panels on, the installation procedures have been changed. Instead
of spray adhesive primer, NSN 8040-00-938-6860, mounting hardware such as
bolts and pop rivets are now used to securely mount the panels to the vehicle.
A CIP installation instruction handbook is now available for download at the PD
TIMS website:
A CD-ROM with detailed installation instructions and a list of NSNs for all Class
IX repair parts is also available. Request a copy by calling Michael J. Murphy at
DSN 987-0377 or (732) 427-0377.
Stryker Alert:
The CIPs kits for Strykers have been modiFed and can now be
mounted on vehicles both with and without slat armor.
Panels mounted on the bustle rack brackets were previously held on with hook-
and-pile. Effective immediately, all units should apply an emergency modiFcation
by drilling holes through the panel and mounting bracket and securing the panel to
the bracket using a bolt and wing-nut.
This modiFcation will keep the panel from being blown off the bracket during
movement while still allowing easy removal and reversal of the panel.
M
ost crewmen eventually learn the lesson, even if it takes a conk on the head: The
driver’s hatch is too heavy to stay open on its own during operation!
There are two safety devices designed to keep the hatch in place and your head from
getting a heavy-duty dent: the stay device and the detent assembly.
Maintenance
Whenever the thin coat
of CARC paint wears off
your CIP, the panel starts
to look like a large silver
mirror. That’s something
you probably want to avoid
on the battleFeld!
Cover
the
exposed
portions of the CIP with
new thermal tape, NSN
This
brown tape comes in 150-
ft rolls and is easily applied
over tape that has lost its
CARC coating.
Do not
remove the old tape. Simply clean the old taped surface with soap and
water, then rinse, dry and apply the new tape over the old. Thermal tape without the
CARC coating still provides the proper thermal signature, but the silver reflective
surface still needs to be covered by CARC to prevent non-thermal recognition.
Stay Device
The stay device is a spring-loaded pivot
support bar with a sliding latch. It’s located
on the interior left-hand side of the driver’s
compartment.
When used properly, the stay device holds
the hatch open at the 10° and 25° positions—
the only two positions allowed for driving
the vehicle. If the hatch springs or the detent
assembly should fail, the stay device keeps that
250-lb hatch from landing on your head. But
only if you use it!
Detent Assembly
As the hatch is raised to each position, the
spring-loaded pin on the detent assembly engages
the teeth on the interlock plate to keep it in place.
If you don’t lube the detent assembly, the pin can
begin to stick. When that happens, the pin may not
fully engage the interlock plate and could slip loose
during operation.
The detent assembly is supposed to be lubed as
required, so do it whenever the pin shows any sign
of sticking. Just pump in GAA, NSN 9150-01-197-
7693, until you see clean grease coming out around
the locking pin. Then wipe off the excess grease so
it doesn’t attract dirt and sand.
It takes both safety devices to keep your noggin
from taking a knocking. So use ‘em both!
