described in paragraph 4. start at valve hole and tighten nipples one
turn at a time all the way around rim until spokes are normally tight.
If possible compare with a new wheel. While tightening nipples,
repeatedly check rim with gauge or dial indicator according to
instructions under paragraph 4.
6. After all nipples have been pulled up, until spokes are normally
tight and wheel is true, seat each spoke head into hub flange with a
sharp blow, using a flat nose punch and hammer. Then retighten all
nipples and finish truing wheel. This method allows spokes to be drawn
tighter at the start and prevents possibility of spokes loosening after
wheel is put into service as the result of spoke heads heating into the
flange.
Do not tighten spokes too tight or nipples may draw through rim. or hub
flanges may be distorted. If spokes are left too loose, they will
continue to loosen when wheel is put in service.
7. File or grind off ends of any spokes protruding through nipples to
prevent puncturing tube when tire is mounted.
REMOVING TIRE AND TUBE FROM RIM
Remove valve cap and valve core to free all air from tube. Remove valve
stem nut. Loosen both beads from rim flanges by stepping on sides of
tire or by using a tire tool. Stand or kneel on tire opposite valve to
push bead into rim-well. Using tire tools, (not sharp instruments),
start upper bead over edge of rim at valve Don't use force when starting
bead over edge of rim with tire iron, because bead wires may be broken
or stretched and the tire ruined Carefully remove inner tube before
attempting to remove second bead. Push lower bead into rim-well on one
side and insert tire iron on opposite side and pry bead over flange.
After a portion of second bead is started over rim edge, tire can be

tire which might chafe an inflated tube Wipe tube and inside of tire
thoroughly with clean, dry cloth. If rim is dirty or rusty, clean it
with a stiff wire brush. Be sure to examine a used tire carefully for
fabric injuries which if neglected will damage tube.
