6 - C.R.F. MOUNTING.

6.1. The screws and nuts position .

6.1.1. Position the nut marked "L" (left hand) in its cavity. 6.1.2. Screw the M16 screw of a turn in each nut "L".

6.1.3. repeat this operation for the two other sectors.

The capsuled micro part (threading of orange color) of the screw is screwed in the nut "L". Nut on the left not identified by the letter "L".

6.2. Move away the side of the tire, vis a vis the valve with a hook. - The tire must be placed on the higher part of the rim. - Caution, don’t move overy to much with the hook (*) on the side of tire.

- The spacing must be 340 mm, sufficient for the introduction of the sectors.

(*) : From which surfaces are protected by bands rubber .

6.3. introduce a sector into the tire.

And to position the nut "R" in its cavity.

CAUTION : NOT TO TOUCH THE MICROCAPSULAGE WITH THE HANDS (RISK OF POLLUTION).

11/21


REFERENCE : PDM 78


6.4. Introduce the second sector into the tire with the nut "R" positioned in its cavity.

6.5. Pre – assemble the two sectors by screwing the M16 screw in some threads.

6.6. Introduce the third sector into the tire with the nut "R" positioned in its cavity.

6.7. Place the sectors on the rim.

12/21


REFERENCE : PDM 78


6.8. Remove the hook. 6.9. Move away the side of the tire with the bead spreader.

- Maximum spacing of the tire 70 mm.

6.10. Pre – assemble the third sectors by screwing the M16 screw in some threads.

6.11. Center the junction fastening device that is centered on the valve.

6.12. Assemble the M16 screws by tightening with the pipe fitter key ratchet.

13/21


REFERENCE : PDM 78


6.13. Introduce the 3 hooks of the chain (cayenne).

6.14. Remove the bead spreader. 6.15. Move away the side of the tire with the hooks (cayenne).

6.16. continue to screw the screws M 16 to bring the spacing between each sector to 33 mm then to 31 mm. 6.17. Use the regulating padlock to inspect the spacing beetwen the sectors.

6.18. Inspect the M 16 screw tightening torque with the dynamometric spanner, the value must be 50 Nm.

14/21


REFERENCE : PDM 78


CAUTION : Visually inspect and with a measuring tape if necessary that extremities of M16 screw have been bolted after the tightening junctions.

6.19. Coat uniformly with the paste gel recommended by HUTCHINSON, (1600 gr) on the internal surface of the tire tread.

6.20. Remove the hooks of the tire.

6.21. Unlock the rim on the mounting support.

6.22. Position the wheel on the machine, lock it.

15/21


REFERENCE : PDM 78


6.23. Pass the second tire bead with the finger of the machine. This operation is made easy by applying TIGRE grease.

6.24. Wipe the grease with a clean rag after passing tire bead.

6.25. Inflate the tire at the acceptable maximum pressure in order to veneer the tire bead. Put back the valve insert. The wheel can be in from now on Inflated to its service pressure. 6.26. Unlock and remove the wheel on the machine.

7.1. Deflate the tire to remove the valve insert. 7.2. Take off the tire bead of the seat side of the rim. Use the lever (*) to star this operation.

ram, - Deposit TIGRE grease on the tire bead in order to facilitate its passing.

(*) : Lever with removed arrises (angles round).

NOTE : Operations 7.2 and 7.3 are to be carried out delicately not to deteriorate the CRF, for that to at least limit the pressure for the separation of the bead of the tire.

7.3. Unstick the tire bead from the rim. 7.4. Remove the wheel on the machine. - Deposit TIGRE grease on the tire bead in order to facilitate its passing.

7.5. Position the wheel on the mounting support.

17/21


REFERENCE : PDM 78


7.7. Introduce the hook over the tire bead.

7.8. Introduce the tire opner over the tire bead. 7.9. Balance the tire opener out and move the sidewall away.

7.10. Heat with thermic tournapull, the left nut (L) for 5 mn at 200 °C. Tilt the end of the tournapull nozzle to located at roughly 20 mm of the nut. - The hot air blown by the gun should not in no case to come into contact with inner of the enveloppe from the separation of the bead of the tire.

7.11. Loosen with the key of 24 mm the screw fastener M16.

18/21


REFERENCE : PDM 78


7.12. Continue to unscrew the screw M 16 with the w rench spanner. 7.13. Stop the loosening of the screw, free once th is one.

8. ANNEX.

8.1. Warning .

8.2. Storage of the screws before use.

- Temperature : between + 5 °C et + 50 °C (+41 °F à + 120 °F). - Guarantee period of joining: 1 year.

- Can be used for one 4 years period if storage in a dry place and at the prescribed temperatures.

- Marking example : 12.03 (Décember 2003) corresponds to the date of application

of the microcapsulage. 8.3. Remark.

- At the time of the assembly of the CRF, it is norma l to have a resistance at the time of the screwing of the bolts, this resistance comes from friction related to the microcapsulage.

- Capsuled micro part of orange color (not on the left).

CAUTION : At the time of each operation of dismantling / m ounting of the safety device CRF, the screws must imperatively be changed.

- Not to deposit a foreign body (grease, oil, f reezing...) on the microcapsulée part of orange color (see photo above ) screws. - Not to touch the microcapsulage with the hands (ris k of pollution).
