8. Obtain a propane torch. Wear protective gloves,
clothing and eye wear. Apply even heat to the rear
housing flange and front spar where it mounts to the
bulkhead clip (arrows in image).
IMPORTANT
Keep flame away from flammable materials. Use
propane torch in well-ventilated area. Only apply heat to
area that requires adhesive bond separation. Do not
apply heat to areas of adhesive where bond line
separation is not needed. Doing so will require
removing the part, removing adhesive, and then re-
applying new adhesive.
9. While applying heat, carefully and slowly pull the
chaincase housing away from the chassis. Use care
as to not distort the tunnel.
