Everything is fiddly on a Traction – this was my first proper resto and thought, this classic car thing is bloody difficult. Now I have started on my Renault 4CV it is a breeze…. so simple, engine and rear subframe out in 15 minutes, engine stripped in half a day….. now sitting on the bench until I can finish it in September 😕 .
So it is the Traction not the fan belt 😆 😆
Maybe use a little washing up liquid on the tight section to squeeze it through. Then wash off the liquid with lots of water before you start turning (so it doesn’t spread to much).
