Hp-41C card reader - dead

[Vintage63]

Good day everyone, hope you and your loved ones are doing well and keeping safe.
Some time has gone by and it is time to update you on this topic.
I'm not in a hurry and this operation takes the time that it takes :-)

Thanks to Tony the o-rings have arrvied, from Australia, and are now in place.
I have started reassembling the card reader but before closing it I did some tests.
I powered the motor with the same 1.5 battery and I've fed a card in it, the o-rings pick it up properly.

BTW - Are cards inserted from the right side ?
I recall they entered from the left but I might be mistaken because they don't !!! :-)

Fiddling with the 'clutch', or axle on which the pulling mechanism rolls, the movement of the card can either be smooth or jerky, so it comes down to having a smooth pulling movement and I need a third hand in order to be able to do this.
I now understand why the axle has a slot to insert a blade screw driver.

First MAJOR problem: the black motor cable came off from its location on the PCB.
Is there a way to solder it in place without damaging any of the circuits around it ?

Second MAJOR problem: screws.
I have taken pictures of the single parts in order to be able to put them back together but did not take pictures before removing the screws, even the pictures on this forum have all been taken with the screws removed :-(
Pictures anyone ?

Thank you and keep safe
Marco
