Hey guys, can you tell me the purpose of the clutch fork return spring? I was talking to a guy at a local car show and he said you don't need it. I'm thinking that it would be used to keep the throw out bearing from riding on the clutch or something.
Yes, it is to keep the throwout bearing off of the pressure plate finger springs. If you look at the AIM, it will show the process for setting up the free play (how much the t/o bearing is pulled away from the pressure plate).
Now, some manufacturers had the t/o bearing riding constantly against the pressure plate. The idea was that the bearing wouldn't undergo lots of start/stop cycles, which would make it last longer. Maybe that's what the guy at the show was thinking of.
