Hi,
Thought I would update you all on the progress of doing an overdrive 5 speed swap into my automatic 113. Due to the kindness of Joe Alexander and Walt Klatt I have most of the 113 clutch and hydraulic pieces that I need. After reading about Hauser's car and seeing several other references I bought a Getrag 265 trans from a 1985 BMW 5 series.
Definately the right choice. The imput shaft looks to be the same which means all the stock clutch components should work. The Mercedes 113 bell housing has the clutch throwout bearing shaft and fork built into it so when I build the spacer I won't have to worry about the length of the throwout shaft.Different pilot size but a custom bushing is an easy machine job
Shifter and driveshaft should be no problem I will probably use the BMW shifter and weld the Mercedes lever to it to give it an original look and feel. Driveshafts are easy you just throw money at them.
Thats all for now I'll keep you posted.
The only problem is that I am out of the country for the next month or so(I work on large private yachts) So until then I order parts to rebuild the trans and a new clutch and hit the ground running in May.
