The clutch disk will always be in a random position in reference to this assembly, plus it has such little mass that it is insignificant regarding the overall balance of the assembly. If you were to choose to balance the clutch disc, it should be balanced separately so that it is in balance "by itself", so that it doesn't contribute to unbalance of the flywheel/pressure plate rotating assembly. 35 Ragtop: You have gotten great advice from everyone. It's just too bad that todays clutch re builders don't do what all good automotive service shops used to do, and that is to set up the fingers on their jig before letting it out the door. So many modern clutches use a diaphragm, and I doubt whether most shops are even familiar with the old Long and Borg and Beck designs. I'm sure that Supereal's shop is, and my local shop is, but for the vast majority, it has become a lost art. Fort Wayne should do it just fine.

This should be checked at the edge of the flywheel and at the clutch surface. The run out should be .005 or less. When you install your clutch, place wedges between the arms and the case of the pressure plate to relieve the pressure on the clutch disc. This will prevent distorting the pressure plate when you tighten the bolts.

If the surface is burned or checked, the flywheel comes off and goes to our resurfacing machine. Occasionally we get a flywheel that has been cut too far. This can show up as a ridge where the plate bolts on. If you find that, the flywheel will have to be machined so the clutch will fully engage. If you find a solid brass pilot bearing, replace it with a sealed ball type. 37RAGTOPMAN 03-18-2011 @ 4:56 AM reply profile send p.m. Senior Posts: 1942 Joined: Oct 2009 35ragtop I would also have the flywheel checked, or machined,make sure it is not cracked,or nay other issues, that might have caused chatter, also relacing the pilot bearing, and check the input shaft for any wear on the nose of it,try a new pilot bearing on it just for ho ho's see if it is tight, my 3 cents worth 37RAGTOPMAN 35ragtop 03-15-2011 @ 1:40 PM reply profile send p.m. Member Posts: 57 Joined: Aug 2010 Thank you again everyone, Im going to address the problem today! Thanks Tomo for the specs, at least when I get the engine out I can check these dimensions. I am ordering a recon pressure plate and new clutch plate from Fort Wayne, have been in touch with them already. Happy Ford ing Dave h TomO 03-15-2011 @ 7:41 AM reply profile send p.m. Senior Posts: 7244 Joined: Oct 2009 Here is a copy of the adjustment specifications. It is very difficult to do while the engine is in the car, and I recommend that you have someone with the fixture do the job. http://i168.photobucket.com/albums/u197/mercurytom/clutch-adj.jpg Tom kubes40 03-15-2011 @ 6:38 AM reply profile send p.m. Senior Posts: 3374 Joined: Oct 2009 Ft. Wayne Clutch is in fact another good place. A bit more costly than Surge but good nonetheless. The fingers can be adjusted without a fixture. There is a specification from the face of the pressure plate to each finger (free state). I have found remanufactured clutches rarely address this specification and as the fingers wear from usage, this dimension goes outside the necessary specs. Unfortunately another example of the seemingly lost art of true quailty workmanship... 39 Ken 03-15-2011 @ 4:31 AM reply profile send p.m. Member Posts: 380 Joined: Oct 2009 Ft. Wayne Clutch has a good reputation. I haven't used them, but I plan to on my next rebuild. Friends that have used them indicate that they do good work. Ken 35ragtop 03-14-2011 @ 2:35 PM reply profile send p.m. Member Posts: 57 Joined: Aug 2010 Well thank you guys once again for your help. When I installed the plate set I did the gentle tighten down routine and everything looked fine at the time. I must admit that I failed to check the contact with the fingers once I had the gbox in place.Only found the problem when I tried to go for a run. Does anyone have a comment on Fort Wayne reconditioned systems ? Dave h
