Mercedes R 107 Seat Height Adjustment

This is one of the jobs I need to do but have avoided doing it for several years! 

The presenter here is incredible.  I have used many of his videos over the years.  I wish I could go over to Germany and just meet him.  What a dude!

There are two problems with this job.  The first is the Rube Goldberg ratchet assembly employed to elevate the seat, and how to put it together properly and lubricate it.  The other is pulling a spring that might be the strongest in automotive history!  The last time I tried to pull that spring back my friend Cliff got hit in the head with a part of a brake tool that broke while trying to extend the spring. 

The best way to do the spring is not to use coins like the British Merc repair guy on YouTube.  You can build a tool like our German friend here, or you can used a combination of boards and a bottle jak to push the spring into position.  that is the way I will do it this time. 

Working on the R 107 is often an adventure, and the seat is no exception!
