SECTION III. INSTALLING A CMB

3. INSTALLING A CMB

3.1

Description: This task covers installing a CMB onto a component.

3.2

General Information: The CMB is attached to an assembly or subassembly by one of two methods.

These methods are not interchangeable. The assembly or subassembly will receive only one of the

two methods. The CMB is either permanently affixed to the component by Hysol® EA 9394 adhesive,

or a CMB tag is strapped to it. See Table 1 to determine which method is required for a given

assembly/subassembly.

WARNING

Use all chemicals in a well-ventilated area. Refer to the Material Safety Data

Sheet (MSDS) documents for the chemicals for specific safe handling

procedures.

Heat buildup during or after mixing Hysol® EA 9394 is normal. However, do

not mix quantities greater than 450 grams, as dangerous heat buildup can

take place, causing uncontrolled decomposition of the mixed adhesive. As

a result, toxic fumes are formed.

Use latex gloves when handling Hysol® EA 9394.

CAUTION

Always use latex gloves during installation of CMBs to prevent

contamination from oils and dirt on hands.

Hysol® EA 9394 must be mixed well in order for the adhesive to bond

correctly. Mix the adhesive for several minutes until the color and

consistency are uniform.
