| Bing, do you have the bearing for the T-5 pressed into the old bushing? If so just find a big socket that is close to the dia. of the old bushing an give it a little tap tap tap-a-roo till it seats. It should go in fairly easy.

Shouldn't have to press anything into the pilot bushing for a T5. I didn't have to, anyway.

When I got the new pressure plate and the disc they supplied me with a roller bearing and brass bushing. The reemed out the bushing and pressed in the roller bearing. I checked and the bearing is the correct size for the input shaft. Bing

I used the Ford T-5, is that what you used? The input shaft is smaller on the tip than the old three or four speed.

I'm using a Ford T5. Now you're getting me worried. That is one thing I did not check because it didn't look different and I had not heard that a different bearing was required. How much smaller are we talking? I don't recall Mummert saying anything about that when I was ordering the parts from him. There isn't a different pilot bearing listed on his site. It even says "Existing bellhousing, clutch fork, throwout bearing, pressure plate and pilot bearing can be reused."
Might we be talking about the throwout bearing? That is smaller on the T5.

| Y_guys On my Ford T-5 conversion, I used a #6203 ball bearing. It fit the flywheel and imput shaft fine, no bushing or anything. The trans was a '93 mustang and flywheel '60 f100 292. Hope this helps............Bill

Might we be talking about the throwout bearing? That is smaller on the T5.We are talking about the PILOT bearing. I just measured the T-5 in my garage and the tip of the input shaft is .590" I don't have an old three speed but I do have an old pilot bushing and it measures .690" so we have about .100" difference. Charlie if you have your old tranny around you might go check the input shaft on it and compare to the .590" measurement, I don't want to tell you any more bad news after your push rod problem, but you might have a bit of slop.

It's .690. So, I guess I have to pull the tranny and find out what it is.
Why would he say it can be reused if it is larger? Wouldn't that cause the transmission to have a failure sooner than later?

I think I'm good. I just looked up the parts in the Timken catalog.
The bearings for mustangs with 302 and 351 engines from 1968 to 1995 have a bore of .671". These part numbers are FC65174 and FC65662.
The 200 6cyl from 1980 to 1982 uses FC65174. 200 and 250 6cyls from 1973 to 1968 use FC65662.
The 4 cyl, 140ci Mustangs use a bearing which is .590"
1974 to 1979 171 6cyls use a bearing with a .593" bore. The part number is F33126.
The bearing for 1955 to 1957 T-birds has a bore of .669" Part number 203S. The same bearing is used for many 1958 -68 with 233, 240, and 292 engines.
Bill's 6203 bearing is 17 x 40 x 12 which works out to about a .669" bore
Based on this info, it looks like you might be using a "light duty" T5. It also explains why John says the stock bearing can be reused.
