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.

9

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.

10

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.
