In the Mexican rallies, I've been going through a stock clutch every 7 day race. I'm going to upgrade to the Center Force diaphram clutch (Summit CTF-DF271739 or 271675) recommended by several forum members. I understand the humps in the bellhousing have to be ground flat for clearance, and the resulting holes covered with sheet metal plates. No problem with that.
What confuses me is the throwout bearing. Some of the forum posts say grind the humps, bolt up and you're good to go. But others seem to have a problem with the throwout bearing. Some talk about a "ticking noise" when the clutch is disengaged, and apparently the problem is that the throwout bearing is a little too big. One post (I think on the Racingstudebakers forum) says the maximum bearing diameter is 3" for the Center Force clutch assembly, and the Stude bearing is actually 3 1/8" (I think)?
Please enlighten me. Do I need to get a smaller diameter bearing? If so, can someone give me a part number and/or source? Does the candlestick on the front of the tranny need to be machined down (because the internal diameter of the throwout bearing is smaller as well)? I'm running a T-85 OD.
Thanks
