My used to have one of those clutches with the notches in the PP. I never had any luck with it. The pedal would hang on the floor when revved up between gears.

Guys, just to make sure: I lubricate inside the pilot bushing as indicated.
Also, the shop manual says no lubricant on the pilot end of the trans drive pinion or splines , but a bit of lubricant on the pinion bearing retainer sleeve,.
Sorry if I sound a bit thick, but I d not want to make this mistake again. Should have the pp and clutchplate back this week :beer:

Ok, I've been away for awhile.
As as been stated, the 3 fingers should be the same height.
I've found the fingers uneven after even slight use.
Discovered that the adjustment nuts are not locked!!
So I adjusted them till they're the same height and tack welded.
End of that problem!
Now, if you use the scalloped 11" clutch pressure plate(with the 10 1/2" bolt pattern)
YOU MUST USE THE CORRECT BOLTS!
These have very small heads.
If you don't use these, the disc will drag against them and you will sometimes or always have the problem you're describing.
My other suggestion is to check your bellhousing dowel pins and make sure they're there, and that the're long enough to properly locate the bellhousing. You may be able to pull them out slightly, for a better fit.
This is especially true if using an aftermarket steel(blowproof) bell housing.
Good luck, and let us know what you find.

Yup. Teaspoon of grease in the pilot busing hole and a thin coating where the throwout bearing slides. "Thick" is not asking if your not sure :D

Let me clarify a this a little bit.If you have an oilite bushing it should be soaked in OIL before installation,and a half teaspoon of grease should go in front of the bushing in the crankshaft cavity.Per the book.

Picked up the clutch and pp today.
71bird, the pilot bushing was fitted when the motor was built, a while ago. All I can say is it looks like brass/copper? as per picture. I have no idea if it was oiled when assembled. All I can do now is grease it, I have also soaked it in a bit of oil as road chicken advised, by taping off bottom half and leaving oil over night..
I'll keep you all informed, hoping to put all back next week ( have to go to France :mad: this weekend unfortunately)

Just for thought, when I said oilite bushing. That was a Mopar invention by the way. It is a Bronze,and something or another mix. That is impregnated with oil in the pores. It releases the oil over time, thats why it should be soaked to resupply the oil. Just food for thought.

Steved, I did not even realise untill today it is LeMans, totally forgot about it. Guess we'll see a few cars on the road going there, the Brits are very supportive of the race. Unfortunately we are just going for a wine run and some good food...
back to the thread then... :beer:

Just a suggestion, but since you have the new parts available- why not take the measurements and re set the old PP assembly. That way, you don't lose out any money and have it on the shelf for the next time.

The bushing is a sintered bronze material. Small pores hold the oil inside and as that wears off the grease gets sucked in. Replace them every time you do a clutch. They do wear and if you can find the roller bearing replacement....even better.

Have fun in France, I'm going to the lake- first time taking the boat out this year. :D

Great suggestion!!
And If the flywheel's off, you can do this on the bench.
Don't forget the disc!!

Just a quick update: fitted the clutch and pp as per discussion, box back in ( for the 3rd time :mad: ).
I lowered the car and all the gears are there!! Still need to do some adjustment on the linkages ( shifting is not very smooth), but it moves easy in all the gears. Firts time in 5 years the Roadrunner moved on its own, although it was just forward and backwards in die garage! :) :) .
A huge thank you to all for the help and suggestions!! :beer: :beer: :beer: .
I am now off to South Africa for 2 weeks, when I am back I am seriosuly going to try and finish the car and drive it :P

It feels great when it finally moves on it's own. It only took mine 3-1/2 years.

guys, correct me if I am wrong but I took out my pilot shaft bushing and installed a bearing. My pilot shaft bushing was shot and I read somewhere that mopar had a replacement bearing instead.
