STRUCTURAL COVER
DESCRIPTION
The structural dust cover is made of die cast alu-
minum and joins the lower half of the transmission
bell housing to the engine.
OPERATION
The structural cover provides additional power-
train stiffness and reduces noise and vibration.
REMOVAL
(1) Raise vehicle on hoist.
CAUTION: On manual transmission vehicles, the
7/16 inch engine block to clutch housing bolts must
be loosened before removal of the structural dust
cover. Clutch housing distortion will occur if this
procedure is not followed.
(2) Remove the bolts retaining structural cover.
(3) Remove the structural cover.
