BONDED COMPONENT SERVICE
Breaking the adhesive bond between the before-
mentioned components is required whenever performing
the following repairs:
• Chaincase replacement
• Left or right bulkhead clip removal / replacement
• Left engine support side brace removal / replacement
• Front tunnel cooler removal / replacement
In every repair procedure listed, the bulkhead floor plate
must be removed. Breaking the bulkhead floor plate
bond will render the part unusable. The bulkhead floor
plate is considered a sacrificial part and will always be
replaced with a new plate whenever removed.
There are two removal methods. The first method does
not require the use of the direct application of heat to
break the bond. This method only involves removing the
bulkhead floor plate and front tunnel bulkhead cooler.
This method works because the adhesive has very little
resistance to peel force and therefore the two parts can
be easily pried / peeled off of the chassis.
The second removal method requires the use of the
direct application of heat to release the bond. This
method of removal only involves the removal of the
bulkhead clip(s) and/or engine support brace(s).
The recommended source of heat is the use of propane
gas, and can be obtained at most commercial hardware
stores.
NOTICE
In all bonded component repair procedures, the engine
assembly and bulkhead floor plate are removed from
the engine compartment.
