Re: worn clutch pedal pivot
Sorry to be so long at getting back, I've been working on the other half's 147, most of the weekend.
Also, sorry for not stating that the 'worn clutch pedal pivot' belongs to the 164, but others may be the same.
When I bought the car in 2000, it didn't take me long to find the pedal pivot hole was worn oval by 30 -50 % of it's diameter! As the clutch action was fairly heavy, no doubt this had something to do with it.
I needed to remove the pedal and either replace it or think up some kind of repair scheme.
The pedal itself is made up of two, thin, steel, sheet pressings, about 0.030" thick (?), welded down the middle. So the actual bearing area was 30 thou" x 2!
As I'm an aircraft engineer, I though this a very bad peice of engineering. You'd never find anything like this on an aircraft (unless it's French ha,ha,ha!). [sorry, for you folks that fly 'Scarbuses']
The solution is to open out the pivot hole in the pedal even more, insert a peice of tubing (with a reasonable wall thickness) and weld it completely around, both ends. This increases the the load bearing area considerably.
When refitting, I used an aircraft bolt as the new pivot pin and a stiff nut, just to make sure it doesn't come apart!
That was seven years ago now and she's still flying!
