The team released a brief video clip displaying a mechanic doing the job on the motor vehicle in the Brackley manufacturing facility on Tuesday early morning, shortly following the transporters returned.
The wheel grew to become trapped following Bottas pitted all through the race and the nut was stripped by the airgun, creating it unattainable to get rid of.
Rather than work additional on the car or truck on Sunday evening the staff opted to save the work for the return to the British isles.
In an before video Q&A Mercedes head of technique James Vowles noted that problems at stops had been not abnormal, offered the great margins concerned.
“The entire course of action is a person and a 50 % seconds, which is it,” stated Vowles. “That’s the system of getting rid of a nut, changing a wheel and refitting the new nut.
“As a end result of that, as I am absolutely sure you can notify, the margin for mistake is quite tiny and if just the slightest trouble transpires, it slows the cease down or likely, in an complete disastrous situation, this takes place.”
Vowles spelled out that the Monaco trouble happened simply because the wheelgun was presented at a slight angle, and that the challenge would be addressed for potential races.
“Our nuts are what we connect with captive, they are maintained in the wheel and the tyre, so as the wheel arrives off the nut goes with it,” he pointed out.
“This nut has to keep a wheel to the motor vehicle these types of it can cope with 5g forces in braking and laterally as nicely.
“It is a large amount of pressure going by means of the axle and the nut and obviously we can never ever have it coming free. So, the gun is an very strong gun, this kind of that you can essentially see the mechanics acquiring to restrain by themselves, keeping on their own to the floor, in any other case they get rotated with it at the identical time.
“Now, what happened is we arrived on slightly angled, so when the socket was now linked to the nut, it a little bit angled relative to it and as a final result of that, now alternatively of distributing the load throughout all of the nut it was across a smaller area and that tore the metallic cleanse off and in fact all of the metal was now removed from the nut.
“As a end result of that, the nut was in put and we have been unable to take out it.
“Plainly, it’s a circumstance that price Valtteri dearly and expense the workforce dearly and just one that we are likely to put methods in location to mitigate.”
Vowles explained Mercedes at first attempted to take away the wheel in its Monaco garage, but then determined to hold out right up until the automobile was returned to Brackley, so it could use specialised gear and examine the concern.
“In the end there we concluded that to eliminate that nut we were likely to will need some relatively weighty tools and expert machines and that would be improved performed here in the manufacturing unit,” he additional.
“Much more so, it allows us an possibility to do an autopsy on it to fully grasp definitely how that nut was worn and gather some clues to enable us to do a better occupation going forward in the future.”
