Stem Insertion Instructions |
|
 |
|
1. Locate the Valve
Stem Insertion/Removal Tool (Item No. 449) like the
one pictured. |
|
 |
|
2. The insertion/removal
tool has internal threads that will screw onto the threads
of the valve stem. |
|
 |
|
3. To install
a valve stem, insert the valve stem through the valve hole
in the rim as pictured. |
|
 |
|
4. Hold the valve stem while
turning the valve tool clockwise, or hold the valve tool
and turn the valve stem. This will thread the tool onto the
valve stem. |
| |
 |
|
5. The valve stem is designed
to wedge into the rim hole and should be tapered. |
| |
 |
|
6. After the tool is secured
to the valve stem, push down on the back of the handle and
align one of the groves in the handle with the lip of the
rim. |
|
 |
|
7. Continue pushing down on
the tool handle like a lever pivoting on the lip of the rim.
This will pull the valve stem through the rim hole. The valve
stem will stretch as it is pulled through the rim hole. Pull
the valve stem through the rim hole until the bottom ring
at the base of the stem is touching the inside of the rim
and the top ring at the base of the stem is on the outside
of the rim. |
|
 |
|
8. Remove the tool from the
stem by turning the tool counterclockwise to unscrew it.
Do not try to turn the valve stem while holding the tool. |
|
 |
|
9. To check the valve stem
for proper installation, gently push the valve stem from
side to side to check for an even, snug fit. The entire top
ridge at the base of the valve stem should be visible against
the outside of the rim. |
|
 |
|
10. Then check the bottom
of the valve stem for an even, snug fit. The entire bottom
ridge at the base of the valve stem should be visible against
the inside of the rim. |

Stem Removal Instructions |
|
|
 |
|
1. To remove
a valve stem, screw the Valve
Stem Insertion/Removal Tool (Item No. 449) onto the valve
stem. |
|
|
|
2. Push down on the tool handle
like a lever pivoting on the lip of the rim. This will pull
the base of the valve stem through the rim hole, removing
the valve stem from the rim. If the valve stem breaks in
half before it can be pulled all the way through the hole,
then just remove the two halves from either side of the rim
hole. Discard the used valve stem and do not reuse it. |
