The Haynes manual and many write-ups I've read say so as well. So why does the Pin on the Flywheel have to face down when you install it? Does it affect the reference sensors in a bad way if you don't? Does the pin have to be in the down position when you remove the flywheel?

Thanks!

 

im not sure, theres only one way the flywheel will go on. I was wondering about that too. its not like it is down any other time when the car is started. but i just did what the manual said. whatever...

 

I 've seen "BS" in the Haynes manual to. But it's still a decent place to get simple info.

 

Face the pin down so that you don't bang it up with the bellhousing. When you install the bellhousing you have to get it under the speed/ref sensor mounting block. There is then a possibility of banging up that stud. That would kinda effect the reference sensor. With the stud down, no worries.

 

Thanks for the info guys. So the position of the FW pin does not have to be in any special location relative to the gears on the pressure plate? The reference and speed sensors operate independently?

 

As far as I know, there is not a relative position needed. The reference sensor looks for that pin to tell the DME top dead center, and the speed sensors "count" teeht on the ring gear to tell the DME rpm. That is MY understanding and I could (my wife would suggest often) be wrong.

 

Hmm, if that's the case, doesn't the pin HAVE to be in a certain position relative to TDC? Not trying to dispute you, Kevin, but I'm just trying to learn a little more about how the clutch system works.

 

The pin does have to be in a certain position relative to TDC but since there's only one way to put the flywheel on, you shouldn't need to worry about it. You couldn't put the flywheel on with the pin in the wrong position relative to TDC.
