Well i am completely new to clutches as i have never owned a manual in my life, but i have a 99 motor and an 01 clutch and flywheel, i take it the two arent going to work together as my 99 motor in externally balanced, but then looking online, all manual flywheels i have found say 99-04. So will it work as is, or should i get it balanced, or buy a new one.

[Onemanzu]

it will work... the engine isn't the important thing, you need to make sure that you have the right tranny and brackets/cables and what not...

also you might have some computer issues too

[99v6stang]

What do you mean right tranny, the t5 is the same from 99-04 isnt it. Also what cables or brakets would change? Everything is exactly the same from 99-04 excpet for imrc (which i just wont use the sensor for), and the balancing which is what im asking about. It is a 99 motor going in an 01 car. How would i have computer issues?

You are sure the flywheel doesnt need to be balanced to match the crank pulley? The motor is externally balnced and i know with a 99 automatic car switching to an 01 automatic motor needs the 01+ flywheel so why would the manual?

[99v6stang]

this should be a crazy easy question for someone, i just want to know is an 01 manual flywheel will work on a 99 motor. If not what is the FASTEST fix?

[Onemanzu]

for some reason i though you were doing a tranny swap...

if your just changing clutch everything from 99-04 will work for your 99

I agree with what onemanzu said.

What you should do is swap the 99 long block into the 01 and use everything else from the 01. This includes the intake manifolds and all the sensors from the 01. I remember this coming up before and there are some differences between 99 and 01 in sensor locations so there could be problems with the engine wiring harness lining up if you use the 99 manifolds. You should compare the two engines carefully to check this.

I don't think flywheels are indexed to the engine so there should be no balance issue.

This would be a good time to put in a new clutch or at least t/o bearing.

[stephen]

Also you need a pilot bearing with the clutch. I would get a new one.

You may also want to get the flywheel surfaced.

[99v6stang]

okey, i am almost 100% sure you guys are wrong. My motor is a 99 externally balanced motor so why would i not need an externally balanced flywheel?

[stephen]

I think the harmonic damper on the front of the crankshaft is part of the balancing system, but the flywheel is not. I know the crankshaft is balanced by the counterweights and the weight of the rods has to be figured into that.

Perhaps you should call Ford parts and have them check if the flywheels are different between 99 and 2001.

[99v6stang]

The harmonic balancer, flywheel, and crank are the three balancing components of the engine, I know my 99 automatic flywheel and my 01 automatic flywheel are different, the 99 has a weight on it. Im assuming that it is the same with manuals, i just hoping this wouldnt be the case as i really needed to finish the car tonight. Can i just use the pilot bearing off the 01 motor or should i buy a new one. Also replace the throw out bearing?

[99v6stang]

i NEED to find a place that can get me a flywheel tommorow or i am going to go insane. I wonder if i can have the external weighs just welded on

[itschristorres8]

99-00 are not nuetrally balanced
the 01-04s are.
but that ONLY effects the flywheel.
the clutch doesnt matter

If you can get the pilot bearing out without damaging it you can reuse it. If the t/o bearing is still good you can reuse it as well.

OK. I checked an online Ford parts list and it shows that the 99-00 flywheel is different from the 01-03 flywheel in agreement with what Chris said. So you appear to need a 99-00 flywheel.

This is where I looked.

If you can afford it you might just buy a new flywheel as the simplest solution, but you could probably find a used one if you call around.
Keep in mind that you may want to get a used one resurfaced and also be sure the ring gear is good.

yea, i already ordered one last night, should be here tuesday. Sucks cuz i wanted the car for the weekend, but nothing ever works out like that does it.

There seem to always be things that hold the job up.

In the meantime you might look at the intake manifold and engine wiring harnesses to see if it will be necessary to swap those parts from the 01 engine to the 99 engine. I'm not sure that's necesary, but I remember something about wiring harnesses not matching up. If you need gaskets you may have to order them. Also take care of the pilot bearing. A new one is ~$10.
