Reading through the posts on both forums and various websites, this looks very much like a project brought to fruition, by a team that worked mostly in isolation until the prototype car was tested on a track…
Track test day Italy, new F1 prototype.
Marketing Manager, ‘Why is it stopped moving? Its only done 10 laps’
Test Engineer, ‘The pinion has come off’
Drive train Engineer, ‘You didn’t push it on far enough’
Motor Engineer, ‘The standard motor shaft is too short to reach the cog and the pinion is hanging too far off the end to stay on the motor shaft’
Body Stylist, ‘Didn’t you all get the email regarding moving the motor back to suit the bodyshell’.
At this point the Engineers depart for a liquid lunch, leaving the Stylist and Marketeer to decide it needs a longer reach toothed thingie with a shaft on the end like the motor has. Returning from an extended lunch session, the most coherent Engineer point out the solution solves one problem but creates two more. Namely a longer closed off pinion where you can’t use a standard pinion puller and any attempt to remove the pinion risks damaging the armature. At this point, as a further delay means launch date is now only achievable via a Tardis, the Marketing Manager is having kittens, until it is realised they can now flog a special tool to remove the pinion and sell more motors...
The above is pure fantasy but you do wonder.
Back in the real world, curious as to why they did this, when they supply axle tubes to space out the wheels to bearings (like the older F1), which in turn controls the cog sideways movement and makes the need for the motor shaft to control the cog redundant. Alternately as some have suggested use axle stoppers. Then the pinion could have been adapted by extending the plain section to give the reach onto the motor shaft and still retain the through hole.
Sloting Plus do a range of pinions with grub screws these are longer than standard pinions and might be a solution.
Cheers
