[W126 Coupe] Seat belt presenter + motor operation

[Dick Spellman]

Hi Asge,

This sounds like a stripped gear on the extender arm motor (a common
problem).  There is a limit switch that stops the motor when the arm
retracts or extends to it's limits presuming the gears are okay.


>From the MB factory you have a nylon gear on the extender motor.  Go to this

info on how to repair.   <

I made the repair he details in 2000 or 2001 on both arms using the metal
gear originally built by Autolux.  They continue to work to this day.  I
think George Murphy at Performance Analysis in Tennesee, USA  now makes or
resells these aluminum replacement gears.

Regards,
Dick
