Remove the connector (J7) harness and connector gasket from the backside of the cover. Take

care that the connector gasket is not lost.

Blocking plate may be removed by loosening four captive screws.

REPAIR OR REPLACEMENT

If captive screws are missing or damaged, install new ones.

NOTE

Installation tool (08524) H7503-8 is required for captive screw installation. Place captive

screw through hole in cover. Turn captive screw into nose threads of installation tool.

Squeeze installation tool handles together firmly. Unscrew installation tool.

Gasket material and insulation are replaceable both on front cover and blocking plate, so

all instructions below apply to both.

Prior to removal of old gasket material or insulation, cut the new replacement material to

size using the old item as a sample.

Remove as much old gasket or insulation material as possible by pulling or scraping it away

from the metal surface.

WARNING

Dry Cleaning Solvent is flammable, and its vapors can be explosive. Repeated or

prolonged skin contact or inhalation of vapors can be toxic. Use a well-ventilated area,

and keep away from sparks or flame. Use goggles, gloves, and apron when appropriate.

Soften and remove old adhesive and gasket residue, using dry cleaning solvent and a stiff brush.

To replace danger plate, use a drill bit slightly smaller than the diameter of the rivet being

removed.

Drill the rivets out and remove the old plate.

Align holes in replacement plate and cover and install new rivets.

Minor dents and bent edges can be straightened using common sheet metal repair procedures.

Panels that are badly dented, bent, or punctured should be replaced.

Should touch up or refinishing be necessary, see WP0016.
