The book says that you must use a new bolt. I know people who have reused the old one and AFAIK, their dampers haven't fallen off yet. At one time, the bolts and the dampers were hard/impossible to get. I think that may have changed and they may be making them again. Also, you may be able to get the bolt from Jaguar.
NOTE: If the crankshaft pulley is not secured within 4 minutes of sealant application, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
Apply a bead of silicone gasket and sealant to the keyway.
Using the special tool, install the crankshaft pulley.
Install a new bolt and tighten in 4 stages.

Stage 3: Tighten to 50 Nm (37 lb-ft).
Stage 4: Tighten an additional 90 degrees.
