ZF to install

From here it looks like steel. As soon as I saw those hot spots I said to myself, "yup, steel". Just an incorrect reaction. Sorry.

I do not really consider myself a clutch expert.
Let me explain my own personal experience with clutches. 1)Ford Van, 302, 5 clutches 2)92 Taurus SHO 4 clutches 3)98 Contour SVT Vortech Supercharger, 4 clutches 4)73 Pantera, 2 clutches
5)68 GT350, 3 clutches 6)67 Shelby GT500, 1 clutch. I think I got them all?

What did Jimmy Hendricks say? Are you experienced? I think I qualify?

The flywheel looks to shinny? I think it is gonna slip?

...oh and as the Southern Evangelist might say, "Brothers and Sisters, I feel you pain!".

My 2¢

My first thought on seeing that surfaced flywheel was.....

Too shiny, too smooth, not correct and going to slip.

Here is a shot of my stock Ford flywheel after surfacing.

And a closeup of my stock pressure plate after rebuilding and surfacing.

Maybe it's not as slick as you think.

Yea, that shot isn't nearly as scary-smooth looking.

...Yes, Pilot Bearing; Right! Did You try the NEW Bearing on the -2 Input Shaft, Dia.= .6695" (17mm)? The Dash 1 has a Smaller Input Shaft at 15mm. I Machined one Pilot Bearing for a Customer with a Beautiful GT-40; the Machine had a different Brand Transaxle than the ZF, That Input Shaft was Only 12mm in Diameter!! The Flywheel will Not Slip!! Just BE SURE to clean Both Surfaces; Flywheel And Pressure Plate, with 'Lacqure Thinner' before Installing. And have You touched the 'Disk' with Your Fingers Yet?? That's a No-No, Nothing touches the Disk; and Do Not try to clean it! You pick the Disk up with a finger through the center hole. Any grease on the Disk face can start it slipping...

You Did ALL those clutch replacements? I wonder if You did any Correctly? Proves one thing!! Your Experienced at Burning them Up!...

Thanks Marlin. You're such a pal. I didn't burn them all up. I had help.

....Hi Doug! I was just 'Rattling Your Cage'! Didn't want to offend You so I removed the writing. I'am sure You have 'Tons' of experience; All needed Here! And You did the Clutch replacements Correctly!! After All; What do I know??...

Were they all done correctly? Hum I'll send you the DVD's and you can grade them for me?

I will say that out of the three Centerforce clutches I've done, the only one that has not caused some level of grief or disillusionment is the Pantera.

As it was explained to me, the clutch that we have now is essentially the same as what was initially invented for an engine that only fully developed 30 hp.

That factor right there explains alot of where the issues come from. That and the fact that when you are behind the wheel of a 500hp vehicle there is a slight tendency to want to stretch ones legs and worry about tomorrow, tomorrow.

There are some thing that clutches just don't like, amongst them things like nitrous oxide, superchargers, Weber carbs, sticky tires, front wheel drive.

Oh, and it isn't that they don't like me, they just heard that I take a lot of them in, along with cats, and they want to help their homeless friends find good homes, and they know that will happen here.

FWIW, here's some info on flywheels:

I have the -2 in the car but the shift shaft hits the universal shaft. Looking back at the shiter box attached to the trans they are different. The das1 in the frist pic has the shaft coming out at a higher plane. ???

About a half inch lower, see the boss on the side of trans?

This where the linkage hits. I thought about turning the shaft around so the adjustment is close to the trunion?

Bill,

The ZF shift shaft and axle/u-joint is a fixed dimension, so the trunnion in your early car must be in a different place creating the angle. Take a photo of that and maybe it's as easy as use a slightly longer trunnion or change the mounting point.

Julian

You may be able to adjust the trunnion up higher if you have enough thread left. The trunnion on my early 71 (not pushbutton) is adjusted all the way up. There's about one half of a thread showing below the bottom nut.

John

My trunion is all the way down and worn. More parts needed

While you are waiting for a new trunnion, try adjusting it up to see if that solves the problem. Also, check for clearance forward of the trunnion .

If you still need more clearance, try your suggestion of turning the shaft end for end so that the adjuster is forward instead of aft.

If you haven't done so already, start soaking the bolts and the shaft ends where they enter the u-joints.

John

Good news... I moved the trunion up, it is still worn out, but by removing my shifter plate and getting an extra spline at the rear linkage I have 5 forwards and 1 reverse! All gears shift smooth. This job is finished. Thanks Bill 1362

Great news Bill!! Glad to hear that it was a "simple" fix.

What is the "extra spline" that you mentioned?

John

With the sloppy trunion. I just had to rotate the shift shaft 1 spline to catch 4-5. I'm just happy that I bought a ZF untested sitting since 1980 and it works fine. Thanks to Ron Parapantera for checkin' it out visually!
