INNOVATOR DOOR HINGE
REPLACEMENT
The following provides supplemental information for
the replacement of a worn hinge pin. In addition to the
hinge pin, it is recommend that the following parts be
replaced.
*Note: If a hinge pin is bent or worn because of
improper shimming, the addition of a nylon spacer
(item 7), attached to the door’s torque rod, may be
required.
In order to address a worn hinge pin, it is necessary to
remove the door from the frame.
Note: The new hinge pin supplied with this replace-
ment kit is longer than the existing hinge pin. These
were designed to be backward compatible.
Tips for replacing the hinge pin and related components:
• Always replace components 1 through 6.
• Torque all retaining screws to 100 in-lbs.
• After removing the pin and spring, clean out any
debris (nylon or metal shavings) that may
be remaining in the door’s “hinge pin /spring” socket.
• Make sure the hinge pin bushing (4551267) is
installed onto the hinge pin (0453783)
• If the hinge pin is bent, it’s because the pin is rotat-
ing on its shaft instead of the top bell. This is most
likely caused by improper shimming. To correct the
issue, order the torque rod spacer (item 7) along with parts
1 through 6.
REPLACING MAGNETIC GASKET
Carefully remove the old gasket from the groove in the
back of the door, Figure 9.
The new gasket will be easier to work with if it is at
ambient temperature. Begin by lubricating the new
gasket with a mild soap and water solution.
