Window Regulator

[Billsmith]

I heard the dreaded pop from my window crank handle and am attempting to replace/repair the regulator.   I need help. 

First, can the regulator be removed with the window and vertical rail in place?  I cannot get the knurled post of the regulator to back out of the hole due to conflict with the vertical rail.  I am assuming that the regulator has to be removed to repair the broken pivot connection?  I have searched the forum to no avail.  Some posts indicate that a Mercedes rivet can be used at the broken pivot point but best I can tell that part is NLA.  Any advice on this will be appreciated since I am a novice.  Thanks.

I remove the glass and the vent window assembly to put in the reg       Some might not take out the vent window but I find it easier       And it is pretty easy to do

 

Thanks, Rick

Thanks Rick.  I just discovered that by taking out the door brake, there is just enough room to remove the regulator. Next issue is where can I obtain a rivet with post like the one that broke?  Any ideas on that?

Get the measurements of the old rivet and see if you can find a replacement here under clevis pins with retaining groove.

I did a column on removing, repairing and replacing those accursed regulators--PM me and I'll send you a copy.  There's a M-B part that'll replace the broken rivet on your regulator...

Do you have the MB part number for the pin?

The most recent number I have is 115-586017-2; it superseded 115-725700-15. 

 

Let us know if this is still a good part number so we can update our files.

 

Cheers

Mike,

I ordered that exact part number online from mercedesbenzpartscenter.com.  It was in their online catalog, order was processed, then order was cancelled.  This was about my third attempt to obtain the pin.  My conclusion is that the part is NLA.

Did you try ordering it from an MB dealer?  MB has their version of BMW Classic and claim to be able to get all sorts of obsolete parts for their older cars.  And I'll wager those window regulators as used on Mercedes wear out just like they do on BMWs, as they're most likely made by the same outside supplier.  

 

The other thought is to find a rivet (aluminum or steel) that's the same diameter. chuck in your drill press and use a hacksaw blade to cut a groove in it for an E-clip, and then cut the rivet to length and install.  Even a properly sized bolt with a nyloc nut will work--not as elegant, but still functionable.

Thanks Mike.  I have decided to "bite the bullet" and replace both window regulators with a pair of new ones I am purchasing from Wallothnesch.  Also, replacing the door brakes.  I am having the "fake chrome" strips on the door panels redone.  Once I reinstall the panels, hopefully they can stay in place for a while.
