REPAIR INSTRUCTIONS
Cup Plug Replacement
REMOVAL
Refer to Figure 130.
1. Using a hammer and punch, drive one edge
of the plug inward. The plug should rotate
causing the opposite edge to move outward.
When the edge moves out far enough, grab
it with a pair of pliers and pull it out.
If, after several taps with a hammer, the plug does
not rotate and is being driven inward, stop
tapping. Drill a hole approximately 1/8 inch
(3.2 mm) in diameter in the center of the plug.
Insert a sheet-metal screw in the hole. Leave
enough of the screw protruding from the plug to
allow a pry bar to be inserted under the head of
the screw and pry the plug out.
2. Clean the plug hole(s) with a wire brush or
wire wheel. After cleaning, visually check the
surface for cracks.
