JONATHAN MCDONALD: If you've ever
wondered if you could put a clutch in your Mustang,
yes you can.
And we're going to show you how to do it
right in your driveway.
Of course, we're going to be on a lift,
just so we can film it a little better.
But you will need average mechanical skill
and a pretty good selection of tools.
Also, beyond your new clutch kit,
you're going to either want to have your existing
flywheel resurfaced or pick up a brand new one.
Couple other things to keep in mind.
Depending on the mileage of your car,
you may want to go ahead and pick up a new clutch
fork, a new pivot stud, new flywheel and pressure plate
hardware, a new rear main seal, and a new transmission output
shaft seal.
If your Mustang is rocking a T5, well, then you probably
want to go ahead and upgrade to a steel bearing retainer
as well.
Follow along.
We're going to get started with the disassembly.
Disconnect your battery.
Remove the shifter boot and remove your shifter handle.
Make sure the transmission is in neutral
and the parking brake is off with the car chopped.
Jack up the car and support the jack stands.
Mark the drive shaft and pinion flange for orientation,
and remove the four drive shaft retaining bolts.
Slide the drive shaft out of the car
and plug the transmission tail shaft seal.
Remove the catback-to-midpipe hardware.
Unplug and remove the O2 sensors, if equipped,
and remove the two midpipe-to-header
retaining nuts per side.
Disconnect the smog tube, if equipped,
and remove the midpipe from the car.
Remove the clutch cable from the clutch fork.
Pull the bell housing-to-cable retaining clip
and slide the cable free of the bell housing.
Unplug all electrical connectors from the transmission.
Remove the speedometer cable and position it out of the way.
Leaving the bolts engaged, remove
the two cross-member retaining nuts.
Support the transmission with a jack.
Remove the four transmission-to-bell housing
bolts as well as the cross-member bolts.
Lower the jack and slide out the transmission.
Grab some help if you need it.
The transmission isn't heavy, but it is awkward.
Remove the two starter retaining bolts
and slide the starter out of the way.
Remove the two lower block plate bolts,
and then remove the six bell housing-to-block bolts.
Remove the bell housing from the car.
Here you can see the reason our clutch failed
was one of the disk hub damper springs relocated itself.
Remove the six pressure plate bolts
hanging onto the pressure plate so it doesn't fall on you.
Pull the pressure plate and disk off the flywheel.
Looks like the disc hub broke, allowing the spring
to come free.
Remove the six flywheel retaining bolts, holding
onto the flywheel so it doesn't fall,
and remove it from the engine.
Pull off the block plate.
Thoroughly clean everything for inspection.
With everything taken apart, now's
the opportunity to slow down and thoroughly inspect everything.
Pay close attention, because I'm going
to walk you through everything that you're
going to want to take a close look at.
Start out with your input bearing retainer
on your transmission, especially if it's a T5.' If it's stock,
it's probably worn, has several grooves in it,
and you'll want to go and upgrade it to a steel bearing
retainer.
Ours has already been done sometime in the past,
and it's still good to go.
Your bell housing spacer plate-- if you
notice any wear around the starter hole,
through it away, put in a new one.
An egg-shaped starter hole will cause your starter bolts
to come loose, and you'll probably even
have engagement issues between the starter and the flywheel.
Inside your bell housing, thoroughly clean and inspect
your pivot stud and clutch fork.
If either one needs replacement, replace both.
That way you don't have wear issues down the road.
On the back of the motor, take a look at your rear main seal.
If it shows any signs of dampness, replace it.
All this stuff has to come out to get to it anyway,
so you might as well do it now.
Same thing with the pilot bearing.
If there's any signs of wear, just go ahead and replace it.
you. can run up your local parts store
and rent you a slide hammer and a pilot bearing tool,
and it'll make the job extremely easy.
If your car still equipped with a stock clutch
cable and quadrant, it really is time
to go ahead and upgrade to an aluminum
quadrant and an aftermarket adjustable cable.
If you already have an aftermarket adjustable cable
and it's got some years on it, and it feels a little bit
draggy, go ahead and replace it.
It'll make your new clutch feel a whole lot better,
and it'll keep you going down the road without any failure
opportunity later on.
If your flywheel has a nice hue of purple and blue little check
marks all over it, go ahead and chunk it.
It's not worth resurfacing, because those spots are now
hard spots, and it will not wear evenly,
even if you have it resurfaced.
If it shows just normal rotational wear,
we do have the option to drop it off at a machine shop
and have it resurfaced, or you can go ahead
and replace it with a brand new unit.
Take a look at all of your hardware.
If there are any rounded-off heads,
any stripped threads, get new hardware.
You don't want to have anything break
or strip out on you when you're going back together.
For all you '79 to '85 owners, this is for you.
Because this car is an '85, it still
had the original 10-inch clutch in it.
This is a perfect opportunity to go ahead and upgrade to the 10
and 1/2-inch that would be found in an '86 to '95 Mustang.
This literally is just bolting on new parts,
as the flywheels are the same diameter and the same bolt
pattern, so they'll bolt right onto the crankshaft.
You will need a 10 and 1/2-inch clutch, obviously,
and you will need new clutch hardware.
The difference is on the '79 to '85,
the hardware is standard thread and it
has a shoulder on the bolt, and that's
what locates the pressure plate.
On the '86 to '95 10 and 1/-2inch version,
there's actually dowel pins in the flywheel to locate
the pressure plate, and it uses metric bolts to retain it
to the flywheel.
Once everything is thoroughly cleaned, inspected,
and replaced if necessary, now you
can go back together with your new clutch.

If replacing the rear main seal, simply pry it out of place,
clean the area, lightly lube the new seal,
and tap it into place, being careful not
to damage the lip of the seal on the crankshaft flange.
If replacing the pilot bearing, use a slide hammer and pilot
bearing tool to remove the pilot bearing.
The center roller of the bearing will come out first.
Then reinstall the tool and remove the outer shell.
Tap the new bearing into place.
Position the block plate back onto the bell housing dowel
pins.
Align the flywheel holes.
Don't worry-- it'll only go on one way.
Install the six bolts using thread sealer and torque
to 75 to 85 foot pounds.
Quick tip-- you can use a couple of pressure plate bolts
and a pry bar as a flywheel holder
when tightening the flywheel bolts.
Make sure the pilot bearing has enough grease and spray down
the flywheel with brake cleaner and thoroughly wipe it down.
Install the three pressure plate locating dowel pins
into the flywheel.
Apply a very light threadlocker to the pressure plate bolts.
Slide the supplied alignment tool into the clutch disk.
The raised part of the disk faces away from the flywheel.
Engage the pressure plate onto the dowel pins
and loosely install the six pressure plate bolts.
Make sure the disk and alignment tool are still
centered and torque the pressure plate bolts to 12 to 24 foot
pounds in a cross pattern.
Remove the alignment tool.
Apply grease to the pivot stud pocket on the clutch
fork along with a thin film in the areas
that the throwout bearing is going to contact.
Slide the throwout bearing into place
and apply a very thin film of grease
to the face of the bearing and a little
to the top of the pivot stud.
Engage the fork onto the pivot stud.
Reinstall the bell housing and torque the six large bolts
to 39 to 54 foot pounds.
Install the two small lower bolts.
Apply a thin film of grease to the input shaft and the bearing
retainer sleeve.
Don't put too much, as you don't want
it to sling out and get all over the clutch disk.
Lift and slide the transmission back into place.
Support with a jack.
Install the two cross-member bolts.
Install and torque the four transmission-to-bell housing
bolts to 45 to 65 foot pounds.
Install the cross-member retaining nuts.
Tighten them down.
Follow up by reinstalling the speedometer cable,
electrical connections, starter, clutch cable, midpipe,
catback hardware, drive shaft, shifter handle, and boot.
If you're running just an aluminum
quadrant and adjustable cable, run up your adjusting nut
against the clutch fork until there's no slack,
and then give it a couple extra tightening turns.
Run up your lock nut and tighten it down.
Test the clutch.
Whenever you push the pedal in all the way,
if it doesn't disengage all the way
to where you can get it in gear, then
crawl back under, loosen up your lock nut,
tighten up your adjusting nut a couple more
turns against the clutch fork.
Tighten your lock nut back up.
Try it again.
Do that until you get a good pedal feel.
If you've thrown a firewall adjuster into the mix,
well, then all you need to do is tighten up your nuts
down at the clutch fork and then use the firewall adjuster
to make all your final adjustments.
Screwing it out away from the firewall
will tighten up the cable.
Screwing the adjuster in toward the firewall
will loosen the cable.
And there you have it-- whole clutch installed.
