New gearbox on its way to Bahrain - 1st April 20:56pm GMT

Ferrari are due to take delivery of a spare F2005 gearbox on Saturday, but the team are hoping to get through the day with the repaired original unit in Rubens Barrichello's car and then fit the new one for Sunday.

A bearing problem stopped Barrichello running in Friday's first practice session, and the damage was so severe that he was not able to take part in the afternoon.

The team is working overnight to make the gearbox serviceable.

The spare was finished late in Italy and was only due to be on hand as a spare for race day. The parc ferme rules should allow the team to fit it after Saturday's first qualifying without penalty - as long as the damage to the old one is deemed genuine and the new one is identical.

Where it might become a little difficult is that, should the repaired box survive Saturday, the team might find it hard to convince the FIA that it is damaged and that they should be allowed to make a precautionary change.
