1. Check the inside surface of metal insert on the new
tire. Remove any scaling or rust with sandpaper.
Clean the inside of metal insert and lubricate with a
soap solution.
2. Place a circular ram on press table. The length of
ram must be longer than the width of the old tire to
allow complete removal of old tire. The outside
diameter of ram must be small enough to fit loosely
in the insert of tire, but large enough to rest
squarely on the flat surface on the outer edge of
hub.
3. If the outside edge of the hub is not flush with the
edge of the metal insert in old tire, measure how far
hub is recessed inside tire. The new tire must be
placed in the same position the old tire was
installed on the hub. A spacer (slightly smaller in
diameter than the inside diameter of tire insert and
the same thickness as the depth of the recess) can
be used to obtain proper amount of recession.
4. Position hub assembly with the old tire on the top
of circular ram so the outside of the wheel is
positioned upward. The outside edge of hub has a
chamfer to help guide the new tire onto the wheel.
The chamfered edge must always be the leading
edge when a tire is pressed onto hub.
5. Center hub assembly on the top of the ram and
make sure they mate squarely.
6. Position new tire with its chamfered insert facing
hub. Align new tire and hub so they are concentric.
