Ferrari Mailing List: Re: LH Gearbox

[Peter Pless (ferrarilist]

Yeah...a bit confusing.

Lewis says he pressed the wrong button.

Ron says Lewis didn't press the wrong button.

Who are we meant to believe? I say neither.

Now it was NOT Lewis' fault for the slowdown during the race:

McLaren has rejected published reports suggesting that Lewis Hamilton's
gearbox glitch in the early stages of the Brazilian Grand Prix, which
effectively cost him the World Championship, was caused by the British
rookie pressing the wrong button on his steering wheel.

Hamilton slowed almost to a halt on lap eight of Sunday's race, dropping
from sixth to 18th place, but was then able to regain speed after being
coached via the radio on how to reset the system. The incident sparked
suggestions that the 22-year-old had pushed the wrong button on his steering
wheel, locking the gearbox in neutral until he was given instructions over
the radio how to reset the system. 

Compounding these rumors was a report in Montreal newspaper La Presse, which
quotes Hamilton directly as saying he indeed pushed the wrong button.
However, a source close to the Hamilton family has described the report as
"absolute rubbish," telling autosport.com that Hamilton had not spoken to
the Canadian newspaper or said any such thing to anyone. A McLaren
spokesperson also denied the report and said the failure was not down to
human error.

"We can confirm that the temporary gear-shifting problem Lewis suffered on
lap eight of the Brazilian Grand Prix was due to a default in the gearbox
that selected neutral for a period of time," she said.
"It was not as a result of Lewis pressing an incorrect button on his
steering wheel."

McLaren F1 CEO Martin Whitmarsh also ruled out driver error and said the
likely reason was hydraulic valve failure.

"It was a gearbox problem, and it went into forced-neutral and changing down
seemed to rectify it - it might be mechanical, but we doubt it," he told
Autosport. "If it was something mechanical, they usually don't fix
themselves. It could be electronics software - but there's no evidence in
the analysis to support that. Could be a sensor - but again, there's no
evidence in the data recordings.

"So it would appear that the barrels that change gear went out of control -
and out of control of the driver - and that's probably hydraulic.

"That could be either a very small Moog servo control valves that were
interfered with by a tiny piece of debris, or they are sensitive to magnetic
interference - something generated a magnetic field which caused the valve
to misbehave."
