Dads bronco eats clutches
My dad has a '66 bronco, and ever since the replacement of the engine with one from the junkyard any clutch we put in wears out within 2 months. Could this be caused by play in the rear main bearing of the new engine(200cid)? Or could this be a tranny problem?

by wearing out do you mean that the disc is down to metal and wont hold or is something else happening. I few more details would be helpful. Sometimes the pilot bushing?bearing is forgotten and the disks rattle apart! lets hear alittle more info

The clutch plate just comes apart, like it would if it was really used. You could hear all the little pieces of clutch fniging around in the bell housing

i would make sure to buy a new pressure plate, replace the little bearing in the flywheel, and make sure to have the flywheel turned and then get what is called a 3 arm clutch... they are the same thing they use in tractors... we use them in all our trucks since we pull trailors pretty heavily.. i love them and they are heavy duty and are worth the little extra money

What engine does he have in it and what trans does he have bolted to it?
I had simular trouble with my '65 F-250. I found out that the trans input spline was not long enough to go all the way into the pilot bushing. Some one had replaced the FE engine with a 292 Y8. Just because a trans and bellhousing bolts together does not mean they are made to go together!! Check to make sure that the input spline is long enough. You will probably never hear this in a book. My cluth discs were coming apart every three hundred miles.
Try going to Ford and ask them what engine and trans was installed in that truck. Don't tell them what you have in the truck because if they have the attitude the Fords guys had in my neck of the woods they will tell you that "if they bolt together then their the right ones." BULL!! That is just their way of saying "get away from me customer, ya bother me." I got that crap treatment for 17 years until new blood was hired.
Take a real good look at that trans-bellhousing-engine hook up. The answer is there.

I bought a 65 mustang that had done the same thing because when replacing the clutch the PO had forgotten the pilot bushing/bearing. There is no support for the input shaft of the trans, so the shaft rattles the clutch disk apart!

What brand of clutches are you using? Are they new or rebuilt?
It could be an engine or transmission problem or even an installation problem.
Are the splines being stripped or is the center and the friction discs coming apart? What does the input shaft look like?
Since it was a replacement engine, did you use the flywheel from the Bronco?
Did the 200 come from an automatic and there isn't a pilot bearing installed?
IMO, the diaphragm type clutch is better choice for a HD application. They give smoother application, easier pedal feel, stronger engagement, and are not prone to chattering like the original 3 finger pressure plates. This pertains more to the V8 applications, though. You take what you can get for the 6 cylinders.
