Highly dependant on where you live for how much labor and parts costs. Best bet is to pick up a phone and call around your city as nobody on the internet is going to give you an exact cost. Labor through the Mitchell estimating guide looks to be around 5.9hrs so use that as a baseline for what the labor quotes will run you. Parts prices can vary, especially if you replace your integral slave cyl/release bearing and send your flywheel out for machining, and which manufacturer you go with for your clutch/pressure plate kit.

 

^^ Could have saved your self a lot of time and given him the ballpark answer he is looking for. And there is no if you replace the slave cylinder. You always do the slave cylinder when you do a clutch.

$450-$550 for labor $250-$300 for a Luk clutch kit. Will probably be closer to the lower end. The parts will include disc, pressure plate and slave cylinder. Best bet for a more accurate quote would be to go to a shop and get an estimate.

Not on a Duratec. All Dtecs come with dual mass flywheels, and those must be replaced with the clutch. I recommend searching out a single mass flywheel replacement. There are several available, but unfortunately those cost just as much as the DMF- because they know they've got you. The only difference is that it weighs half what the DMF does, and the next time you do a clutch you might not have to replace it unless you let the clutch go so far that you grind the heck out of the flywheel. For about $100 more than a steel SMF, you can get aluminum, but get ready for fun. Aluminum flywheels tend to make you stall out more, spin out more, and have more difficulty on hills- especially in the rain. Clutches don't last as long as a result of what you have to do to get moving under those situations. SMFs compared to DMFs will give you a more dogged engagement and rougher gear changes. DMFs are more common on vehicles like BMWs and VWs that value smooth changes over performance feel, and the owners don't care what it costs to replace.

$300-400 for flywheel
$500+ for clutch kit

optional parts:
$60-80 for Clutch slave cylinder

I generally replace those when doing a clutch. In this vehicle, it will come with the release bearing glued to it. Depending on how long the glue lasts, it will prevent the rattling noise that we sometimes hear when the clutch pedal is up in N. IMO you should always replace this with every clutch. With some kits it comes in the kit, so read carefully and make sure you're getting your money's worth.

I just did all the research on this a few months ago. I have an 05 also, and I'm over 140k, so I know a clutch is coming in the future. I'm glad I researched it so I could save sufficiently. You certainly don't want a Dtec clutch job to surprise you.

 

Search the Duratec Performance forum for clutch kit, and you'll come up with some good resources. There are clutch kits out there for $300 for that car, but nothing will save you from the cost of replacing the DMF.

 

I only have 65,000 or so miles. I don't know whats wrong with the clutch, but I know that it drags as the gear grinds sometimes going in/out of gear after the transmission had been put into a gear and held in place.

It's not slipping, but something is causing an intermittent dragging.

Where does it say flywheel must be replaced?

The TSB for clutch delamination says the pressure plate and disc must be replaced at the same time, but does not say anything about the flywheel.

 

That sounds like you might have a little air in the clutch slave. You can bleed it to be sure. You might end up having a leaky slave cylinder. I had a friend with that problem. He'd get a little bubble of air about once every 6 months, but he never called me until it got to the point where it wouldn't shift into gear. Grinding while shifting was a symptom. If I were you, I'd learn how to gravity bleed that system. That's all I ever did to his. It took like 5 mins. It is not worth changing it out for this problem, and you will not notice a drop in fluid level as a result of this sort of slave cylinder failure.

DMFs must be replaced with every clutch change. It is a part that wears out. A SMF, single mass flywheel, is one piece of metal. You can resurface those. DMFs are 2 pieces of metal separated by a spring mechanism that allows the two pieces to turn slightly independent of each other. This takes some harshness out of shifts, weighs a lot, and requires replacement with the clutch.

Check this thread out Duratec Clutch Kit
Somewhere in there I posted a link to a good explanation of how DMFs work. There is plenty of information online about DMFs. Basically, it's a part that wears out, so it must be replaced with the clutch.

 

Wow.. how many times can you say "requires replacement" in one post? I need more coffee.

 

I recently replaced my clutch, and yes you want to replace the flywheel. Let me tell you why. I replaced the clutch in my car about 2 years ago and as a cost saving measure I did not replace the DMF. My clutch started slipping again after 15 months. So i now have a Stage 3 clutch and an aluminum flywheel. If I had done it right the first time and replaced the DMF I would not have had to replace it 2 years later. It is not a fun job.

You can get a stage 1 Exedy clutch kit (clutch, pressure plate and Flywheel) from FSwerks for about $630.

 

FSWerks has the Exedy OE clutch kit with flywheel listed at $425 slave at $80

 

Yes part number FS107= OEM clutch kit with flywheel = $425

Part FS106 = stage 1 clutch kit with flywheel= $625


I seriously don't think he needs either. I think the slave needs to be bled. I suggest a gravity bleeding. Make sure the car is parked on as level a surface as possible- this is very important. First, pump the clutch pedal 10x all the way to the floor, then add fluid to the reservoir to the max level. Leave the cap off. Now open the bleeder nipple on the slave cylinder which is exposed outside the transmission facing towards the front of the car IIRC. Within a few seconds you'll see a bubble. Wait until fluid runs clear which really should take just a few seconds. It only takes a tiny bubble to screw up a slave. Close the nipple, wipe up spilled brake fluid (it's evil paint peeling stuff), and put the cap back on the reservoir. Drive and see what it feels like now.

 

The Exedy kits come with a single piece flywheel to don't they?

but yeah it does sound more like a bleeding problem or just adjusting the shift linkage.

 

Yes, 13 lb single piece steel. OEM DMFs I've found were $300ish. I think the stock flywheel weighs like 27 lbs or 34 lbs--- I can't remember.

 

Holy hell!! So putting a single piece on is cheaper and will save you 14+ lbs. There has to be a drawback in there somewhere...

I never realised how "easy" It was to lighten up the rotating mass on a Duratec.

 

Clutch wear. I'm currently rolling on 140k on the factory clutch. I expect to outdo my previous 160k mile record on the Aerostar (yes I had a 5 spd mini-van). DMFs absorb a small amount of your rotational forces making shifts. That makes shifts less abusive on passengers, engines, and clutches. Lower rotational mass always reduces clutch life because you have to slip the clutch more to get moving without stalling. I can nearly engage 1st in my car on flat pavement without hitting the accelerator. I've never been able to come close to that with any vehicle. Once you're moving, that rotational mass doesn't really effect anything except slowing down engine deceleration.

 

What's the difference between various clutch kits? I see that kits for Focus range from $200-600 with one Exedy brand one EH05SD that cost like $1,400.

I need something durable and can handle reasonable abuse like accidentally dropping the clutch from when my foot slips off the pedal and the like.

Differences in friction material, pressure plate force, and whether or not a flywheel comes with the kit, and if that flywheel is aluminum, steel, or DMF. As far as what's what- you'll have to do your own research on that, and most of it depends on what you want as far as performance from your vehicle.
