Refitting Front Tire (No security bolt)
|
|
|
|
1
|
If the tire has been removed completely, ensure
that the rubber rim tape is fitted properly, rough
side towards and central in the spoke nipple area
of the rim.
|
|
2
|
Replace the valve core and inflate just
sufficiently to "round" the tube and minimise the
risk of "nipping" at a later stage. Dust the tube
with French chalk and place the tube inside the
tire.
|
|
|
|
|
|
|
|
3
|
Lubricate the headings with soapy water.
|
|
4
|
Squeeze the headings together with the hand,
permitting the edge of the tube to protrude for
approximately 2 in. (50.8 mm) at each side of the
valve. Offer the tire and tube to the rim, feeding
the valve through the rim tape and rim holes.
|
|
5
|
Pressing this side of the tire into the rim
well, and working from the valve, press the first
beading over the rim by hand pressure and lever the
last few inches into position as in Fig. H22. Take
special care that the inner tube is not nipped
during this operation.
|
|
6
|
Press the second beading into the rim well,
starting opposite the valve then use the heel to
press the bead into position as far round as
possible.
|
|
7
|
As shown in Fig. H23, taking care to avoid
"nipping", lever the last portion of the beading
over the rim, finishing at the valve.
|
|
|
|
|
|
|
|
8
|
Push the valve inwards to the rim to ensure that
the tube near the valve is not trapped between the
beading and rim then pull the valve back and
inflate to pressure.
|
|

|
To ensure that the tire is true on the rim,
check the tire moulded fitting line in relation to
the rim. The position can be corrected by
"bouncing" the side of the tire on the ground at
any point where the fitting line is too near the
rim.

|
When the tire is fitted correctly, fit the
knurled valve securing rim and replace the valve
dust cap.

Removing Rear Tire (Security bolt
fitted).
|
|
|
|
The routine for removing and refitting a tire
with security bolt is basically the same as for a
tire without security bolt but it is important to
deal with this item in the correct sequence. The
full procedure is therefore detailed as follows:
|
|
|
|
1
|
Remove the dust cap from the valve and using a
suitable notched type of cap or removal tool,
unscrew the valve core to deflate the tire
completely.
|
|
2
|
Remove the knurled ring securing the valve at
the rim. Store the cap, core and knurled ring clean
for re-use.
|
|
3
|
Unscrew the security bolt nut and push the bolt
inside the cover.
