NOTE:
Do
not
allow
contamination to cover mating faces of lockring (6)
and rim (3).
Check to be sure that proper rim parts are used
for reassembly. Use of incompatible parts may
not properly secure the assembly resulting in
violently flying parts upon inflation
2. If valve stem and spud assembly were
removed, reinstall in rim. Install valve stem
assembly onto rim and install spud assembly to
inside of rim. Tighten spud assembly to 4 N·m
(35 in. lbs) torque.
3. Adjust vinyl clamp and cap screw on valve stem
and rim assembly. Tighten cap screw to stan-
dard torque.
4. Install inner flange on rim. Coat beads of tire
with tire mounting soap solution.
Prying against tire bead may cause damage to
tire bead and will cause air leaks.
5. Position tire over rim and work tire on as far as
possible without prying against the beads. Any
damage to tire bead will destroy air seal and
cause air leaks at these points.

6. Install outer flange (5, Figure 2-8) in position
and replace bead seat band (2). Push in on
bead seat band to expose O-ring groove in rim.
7. Lubricate new O-ring (4) with soap solution and
install in groove of rim.
8. Install lockring (6) and tap into place with lead
hammer. Lockring lug must fit into slot of
rim.
9. Remove valve core from valve stem and inflate
tire to seat beads of tire and O-ring as specified
by tire manufacturer.
Use a safety cage whenever possible. Stand to
one side as tire is being inflated. Never start
inflating unless lockring is securely in place. DO
NOT stand in front of or over lockring when
inflating.
10. If beads of tire and O-ring do not seat within one
minute, raise tire slightly and tap bead seat
band. This will help the air pressure to push the
tire bead out into position.
11. As soon as seating has been accomplished,
install valve core and inflate tire to recom-
mended tire pressure.
12. Follow tire manufacturers recommendations
concerning tire bead seating procedures and
final tire pressure setting for each application.
