A77 re-centering spool motors on chassis

[Lpr35]

Good morning to all. I have here a problem on A77, because I must remount two spool motors on chassis, but I have seen that there is air space among the hole on chassis and the motor body . 

Is there a system for re-center well the motors than the chassis ?

Thanks to all .

Hi, ehrlich gesagt weiß ich nicht, wo dein Problem liegt. 
Die Wickelmotoren werden mit vier Schrauben befestigt, fertig. Da muss nichts zentriert werden!

Sorry, but someone can explain me why there are 4 holes on chassis from 4,70mm each, while on motor 4 holes with thread M4 ?

Why have 4,70mm on chassis, than 4mm necessary for the motor ? At my eyes there is a no-sense ... Revox was famous for their precision manifactured recorders, but in this case the precision there isn't...

For this reason I asked if there is a system for re-center each motor on chassis correctly.

At a guess I'd say there really is no need to center the spool motors on the chassis. I can't see what difference a maximum of 0,35mm either way would make.
The way the Revox brakes work, they won't have a problem.
