Take pictures of the Linkages before you take them out - It will help during re-assembly.

No Way wayne - I have Extras in my attic with the same fabric and I Bought out an Vintage auto upholstery warehouse - I have yards of that stuff.. Plaid On Brother!


anyway back to business:
I pulled the trans and old PP / Clutch / Flywheel out of the Duster.
Image

Test fit the New disc on the actual trans in will be going on.. No issues.
Image

Old Greasy Bell and other stuff will get a bath in the parts washer!
Image


Image


Here are some shots of the Old Flywheel, 10" custom Disc that I had used and Custom 10" Borg& beck Press. Plate.

The Old Disc and Press. Plate were made by a local clutch Rebulder - He has since Retired and Closed Shop :-( I know of no one in the area now that does custom clutches; hence this install.
Image


This B& B Press Plate Has 12 Springs and I believe 2400# Holding force.. Good for a daily driver but it is the exploding Cast Iron Stuff :-(
Image


Image


Image


The Clutch Was a stock Borg & Beck 10" with 9 kevlar Buttons on it - Those buttons used to be 1/8" tall when It was new. :shock:

Pressure Plate Finger Height Comparison.
Pay attention Here! This Is important for Making your Clutch Fork Pivot Shims.

Stock PP:
Image


Image

This Measurement Looks to Be Right Around 2 3/4"
Image


New McLeod PP Finger Height:
Image

This Measurement Appears To be 2 5/8"
Image

I will use this measurement to setup the the new Clutch Fork Distance - Based on my own other project with the McLeod parts, and others who have used these parts before 2006 You might have to shim the Clutch fork 1/4" to 1/2" Closer to the Engine to get correct Pedal travel & clutch rod geometry.

For those of us considering a 4-spd swap but who know next to NOTHING about clutches and such (unless I'm the only one here...),

Best. Thread. Ever.

THANKS, GREG!!!!!!!!

This should definitely be a sticky...

Well - A Moderator has Made this a Sticky!

Thanks Mods!

I have been pretty busy with work & other things so it's been a few days since my last update..

I have been piecing together the parts for this install and I noticed something of concern.
I am trying to get an expert answer on this before I forge ahead with the project.

I had particiaped in theWilcap AL flywheel Group Buy back in 2008.

This is a super nice flywheel (i will do a weight comparison soon) that (if you read the old post) I was adamant about the Flywheel that I ordered having the Ford 10" pressure plate mounting holes drilled onto it.

Well they are drilled on The Wilcap Flywheel and the PP i got last week from Summit/McLeod Fits fine on the Flywheel.

My concern is the Steel Friction insert:
Image
As you can see the insert is only 9" in diamater and the Clutch I want to use with this package is 10" and the PP is also 10".

Image


With the Steel friction insert being only 9"..........1/2" of the clutch disc and pressure plate will overhang this steel insert.. I am not sure i that's a good thing.
Image


I am waiting to hear back from wilcap to see if the Steel insert can be replaced with a 10" piece. I have not heard yet.


The other option will be to by the Steel SFI certified McLeod Flywheel Part# 464001

Since I had the Wilcap Piece in storage in my shop I wanted to use it - The Mcleod Piece will be some more ca$h that I would like to hang onto if possible.
I have one of the McLeod Dual Pattern Flywheels in the Dart - no problems - I just wanted to use the AL flywheel on this project.

We shall see.

If you have any thoughts on this chime in.

The friction surface on the flywheel needs to match the disc. If it doesn't you're losing a lot of clutch area.

Let me know if Wilcap will redo the insert. I'd want mine done that way too. Thanks again for great thread.

I spoke with the Fine Folks@ Wilcap and The 10" insert on the Slant AL flywheel is a no-go - THe technical reason is that there would be no meat left in between the AL the Steel insert and the Ring Gear Rivets..

The AL flywheel will be a 9" to 9 1/2" only clutch piece - I suppose I could get a Nice 9" PP and make that combo work - But that will be on another project..

I ordered the McLeod 464001 Flywheel and Once that comes in I will continue with the Install.

Post subject:  Cleaning / Shimming / Trimming 3-26-12

Here are the Next Step(s) in the Process:


Before Re- assembly of the clutch / PP / Flywheel I like to Clean the Bell Housing inside and out before the Reinstall:

Using The parts washer All the old greasy Gunk and clutch dust are removed from the stuff I am going to put back into the car:
Image


Image

The stuff is clean Now!
Image


Image



Even though I am not re-using the Old Flywheel on this project; I am cleaning it and Sending it to the machine shop for surfacing; I will stash it away and Possibly re-use it on another project Later
Image


For This pressure Plate Install I will have to shim the Clutch Fork Pivot Closer to the Flywheel / Engine - If you are using a stock type Pressure Plate this step is NOT Needed.
Image


Image


I removed the Old Clutch Fork Pivot and Used it to layout some bits of Steel to make the spacer.
I marked the holes and Got the general outline for the Spacers.
Also the Stock Bolts That hold the Fork Pivot will be waaay to short so I will replace those too.
Image


Here are some shots of the Spacers I made - I was using some left over angle Iron and Made the spacers - No they are Not Billet, nor are they pretty but they will do the job.
Image


Image


Image


All 3 spacers are done; they measure about 1/2 Inch which should be just right for this setup - I can always unbolt the fork pivot and add or subtract the spacers to get it right.
Image


Image


Next are some shots will all the spacers and Clutch fork pivot installed and bolted down.. Notice the longer bolts needed for this.
Image


Image


Image


Image


Image


All complete and A New Throwout bearing too.. I usually Toss In a New TO Bearing if I have the tranny out and I dont want to do the job again anytime soon.
Image


Now Lets take a look at that 10" Ford/Mazda Pressure Plate from McLeod.

I had some trouble with the clutch hitting / binding on the bolt hole material of the Pressure Plate Hat when I did this install on the dart back in 2006 - It is much easier to cut / grind these tabs before the install raher than after.
Image

The Pen points to the Black line where I am going to make the cuts;
This will happen on 6 of the mounting points.
Image


Image


Image


Tools I used to do this hack:
Image


Bits Removed - Not Much but enough to alleviate hassles later.
Image



Photos of the PP after Cutting the six Little tabs off:
Image


Image


Pen Points to where the cuts were made:
Image


Image


Next:
Test fitting the PP / Clutch / Flywheel / Clutch rod etc..


I have to Wait for the McLeod 464001 Flywheel to come in to do this.

Greg, It would sure be nice if McLeod could get the center registry right to start with. I know it is not a huge deal, but it should not need to be taken to a machine shop out of the box. It cost us $40 and 2 days of waiting to get ours done.

Maybe this one will be correct? Let us know. great write up by the way!!

What makes the stock flywheel not a good choice for this mod?

Author:  Greg Ondayko [ Fri Apr 13, 2012 8:16 pm ]
Post subject:  Parts Update 4-13-12

@ Junior - Well I would not use the Stock Flywheel for 2 reasons -

#1 It's made from Powdered metal - Like cast Iron I suppose.. In a performance situation Things could fly apart and this can hurt or seriously hurt someone Not to mention damage you car quite a bit.. I have been there - Not fun.

#2 to use the Ford 10" PP the Bolt pattern for this on a slant Flywheel Has to be VERY close to the edge.. Near the ring Gear - The steel piece will do a better job with this small amount of material near the edge of the bolt holes.. and Not to mention you have to find a very competent machine shop to modify you stock PP to do this.. Could it be done .. yes I would not choose to do this.



Update... I ordered part #McLeod 464001 This time I used a local guy in town that was cutting my old flywheel - He is a McLeod Dealer - So a few weeks go by and I get the flywheel in.. I ask him to check the Center register - 'cause If it needs machined out to 2.165" (i am installing in a '68 up application) He could do this before I picked up the part.. He verified that the part had indeed come in with the '68 Up register... Great.

So I get home and notice the pP mounting patterns look funny...

It came with 2Sets of Mopar Borg& Beck PP Mounting holes drilled on it.

This certainly wont work.. Currently Waiting on a return to McLeod for a correction on this. :-( Will post updates when Info is available.

I did not have this problem 6 years ago with the part in the Dart - It was right the first time with the dual PP mounting pattern.

If you are interested in this flywheel maybe call McLeod Tech and Be sure to verify the 2 Patterns before they make yours.



Pics:

Here is the New McLeod Piece - Weighs 20#
Notice the "double" stock PP mounts..
Image


McLeod Piece Came in with the large Register:
Image


Stock Flywheel Has been Cut a few Times - Weighs In @ ~17#
Image


The Ford 10" PP does not line up anywhere on this McLeod Unit - It should - They screwed up:-(
Image

Shots of the Stock PP lining up on 2 Sets of Holes. - Dumb

More to come when info is Available.
