- www.bavauto.com -- In this How-To DIY video series (Part-1 and Part-2) we will be replacing a typical BMW clutch and flywheel. For more details on this DIY, see our Tech Blog at www.blog.bavauto.com/go/clutchrepair . These videos show the full removal, replacement and reassembly of the self-adjusting clutch (SAC) and dual-mass flywheel, special instructions that MUST be followed in the installation of the self-adjusting clutch, failure modes of the dual-mass flywheel and finally, installation of the UUC lightweight flywheel and performance clutch. We will also install the UUC Short Shift Kit and DSSR. See the separate DIY video for the shifter install at www.blog.bavauto.com/go/shortshift . All of the parts shown in this DIY series are available at Bavarian Autosport. Visit our online store at www.bavauto.com or call or knowledgeable agents at 800-535-2002.
Don't forget to "like" this video and send us some comments!
I never heard of your website before, but I am definitely buying some parts from you guys. If you put this much effort into DIY videos, that means you really care about your business and your customers.
This is not just slap-on job, these are very carefully produced videos. Great customer service means a lot to me and you guys certainly deliver.
Nah it means they want the bands
Thanks for the encouraging words. We certainly do want to help our customers with their BMW ownership and we are, indeed, enthusiasts ourselves.
Thank you for this informative video. I wish more local motor technicians have the courage to advise their customers to replace with the single mass flywheel.
Personally I find the irony in the replacement of the DMF with a solid flywheel and non-adjusting clutch kit as too much to take...!
We do cover the complete process for clutch replacement in this two part video. If you have further questions, please feel free to give us a call at 800-535-2002.
This looks fun to do whilst lying on the floor of your driveway
A small lateral (Push-Pull left and right) play is normal and even exist on a new dual mass flywheel.
Thanks for the video. The clutch started slipping on my 1998 M-roadster (S52) last week, car has 83K miles. This video was a nice refresher for me, it's been a few years since I have replaced a clutch. I forgot about the pivot pin and exhaust gaskets!
"Torque it to the specification" - it would be nice to know those specifications, could you just mention those on the video?
Fcp euro has a video showing all the torque specs on an e46
Leave 1 bolt to hold the flywheel while you pry it off the crankshaft. Easier than playing catch with a big piece of steel.
Sie sind ein sehr guter Lehrer, danke für ihr Video, ich konnte viel lernen! 🤗

The MechanicAll penetrant is far superior to WD40, but does cost more. Click the link below:

One minor, but incredibly important detail when removing the transmission is to make sure you have REMOVED the speed sensor, also known as the crankshaft position sensor, also known as the pulse generator. I missed this step on my 2003 M5 and it cost me at least a half hour trying to wrestle the transmission from the engine, and it also cost me the sensor. I don't know if this sensor is present in all E39's, but it is definitely there in the M5.
Brian Flomer - We can't reply directly to your comment as it was sent in via Google. The starter does need to be disconnected from the transmission bell-housing. You can leave the starter in place, but the two mounting bolts must be removed. If the transmission is moving but will not fully separate, we would say that either the starter is still bolted in or the small bolt on the shield plate is still in-place (on the passenger side, from the front). If the trans will not move at all, you likely still have a main mounting bolt to remove.
Brian, if you have all bolts off (including the metal shield), the dowel pin in the starter may be the suspect. It can become corroded and can take a great deal of force to break loose. Spray some penetrating oil on it and use some extensions with a metal punch to push it from the rear toward the front of your car. Good luck!
Adam Krick
- Good input Adam. We've dealt with that!
Hey Craig Bettridge, the starter is only attached to the transmision with two bolts that you remove on the transmission side. There's also a dowel that I mentioned in a comment that gave me a very difficult time. I took some sand paper to clean it up before reinstalling it. I'm not sure if you've ever heard of it or not, but www.realoem.com/bmw/select.do has very helpful diagrams specific to your BMW. Just punch in the last 6 characters of your VIN at the top and it's pretty easy from there.
Adam Krick thank you for the link!! I noticed it after sticking my head right up in the drive shaft well.
Bavarian Autosport how much would a job like this cost on a e38 740il
This might be a dumb question; will this be somewhat the same for an 06 530i with an SMG transmission?
For the most part, yes. You will be dealing with the SMG parts that operate the clutch and shifter hydraulically, but the transmission and clutch assemblies are pretty much the same.
this looks professionaly done!
well narrated and well explained very clear I have learned a lot from this video
Thank you very much. Actually the issue was re manufactured clutch back up wheel. Took it out and it had a crack on through the body
Under rev it would create dis balance and eventually would destroy the crankshaft bearings
Yes ... the only differnce on the SMG is the automated clutching and shifting. The transmission is basically the same as the standard transmission.
Nice to recommend the Bentley manual - however Bentley doesn't have a manual for my car - 2007 BMW Z4M Roadster
Very, very precise work! Well done!
Yes, the overall procedure would be similar to what we show. Some details will differ, but you certainly could use the videos for basic instruction. the Bentley repair manual would give you specific details. We have them at bavauto.com.
At 8:00 Otto is absolutely INCORRECT about using that tiny amount of rotational freedom to determine that the DMF is worn out.
To prove it to you just search youtube for a video called "The LuK DMF - its function, diagnosis and repair
" and go to 3:28 of that video to see what the internals look like.
Keep in mind that this channel is about SELLING parts.
If the flywheel has play, as the one in the video did, you will find that the vehicle has a jerky feeling when starting out and when changing throttle application. This vehicle also had a surging feeling when driving at a constant speed, due to the flywheel surface bouncing back and forth at light loading.
amazing quality. This is the equivalent of a shop class on BMWs with incredibly succinct detail. Thank you. Do you have any videos on making my own home time machine?
We have the time machine video in production now. Should be done by April first.
Well ..... if the head is too beat up to accept the Torx socket, at this point, there isn't much you can do besides pulling the engine and transmission so you can actually get to the bolt. You can try hammering on a regular 6-point socket (match one up with one of the removed bolts), as a last ditch effort. If you can get one on tightly, try to turn it by hand ... not with an air-tool.
In a general sense, yes it does. Your details will be a bit different, but the overall procedures will be quite similar.
Get rid of dual-mass for much smoother operation, then why is there dual-mass?
Thanx for awesome vids/ David, Sweden
Because he is talking utter BS, it’s not smoother, just less issues
Yes, the disc is marked as to which side goes toward the engine or transmission.
THE BEST VIDEO EVER IN YOU TUBEI.
In the video it looks like you reused the old dual mass flywheel on the rebuild??
But a very informative video thanks
The main video shows installing the aluminum flywheel and performance clutch. We did also show how to install a replacement self-adjusting clutch, as a side note. In this section, we did show this on the old stock dual-mass flywheel. If we were completing the install using a stock clutch set-up, we would have either replaced the dual-mass flywheel or installed the dual-mass & self-adjusting elimination kit.
You guys put a new clutch on a worn flywheel
I noticed that too lol I was like, "WTF?"
Yeah me to haha,and he was talking about it and then he puts the worn in 🤔🧐
they also used a LUK clutch set instead of the one that he talked so highly of lol
It's all down to the customer...?
If you watched part 2 you wouldn’t write that comment.
Unfortunately, we can't have every agent being a full 100% technician. However, we should have offered further assistance to you. Anyway, if you crossed the sensors and have then installed in the wrong positions, the engine will not run. Secondly, if the pin on the side of the flywheel was damaged, the position sensor will have nothing to read. Did you replace the flywheel, by chance?
Without driving the car, it's tough to make an accurate diagnosis. However, it does sound like the noise is coming from within the transmission, from your description. What fluid are you running in the transmission? Have you tried the RedLine MTL? See it on our site at bavauto.com . Another thought would be to try the Red Line 75w-90 fluid (it is OK to run this) to see if this changes the noise at all. If it does, you know that it is from within the transmission.
The OnePiece flywheel it doesn't Drive smoother. it gives more vibrations on the carbody in lower rpm.(Diesel)
BavAuto is the one stop shop for all your bimmer needs and that is a fact. I do have one question however, why did you guys not replace the flywheel on the car after saying it was bad?
We did replace the flywheel ... we installed the UUC aluminum flywheel!
Ahh I didn't see part 2 before writing that. UUC Lightweight flywheel is the way to go for sure.
excellent video as usual
2:45 STARTS THE REAL DEAL!!!
Very useful and wee presented. Thanks.
THANK YOU!!! SO VERY MUCH! I'll be doing this in a month or two!
Great video! I am doing the clutch assembly on my 2002 325ci and I was wondering if I needed to support the engine while removing the transmission. I see that your engine appears to just be moving freely. Thanks for your help!
On the BMW applications, we have found the conversions to be very smooth and solid, when installing the heavy conversion flywheel kits. the lightweight conversions, using the aluminum flywheels, have a bit less damping due to the lower rotational mass.
I'm going to buy a single mass flywheel conversion kit for my 2001 Z3 3.0i and I was wondering about replacing the master cylinder if you're going to replace the slave cylinder anyway? Is that necessary? Otherwise, very informative video. Thanks
Well ..... if the engine is running properly and smoothly, then the next probable cause may indeed be a very worn out dual mass flywheel. Typically, you would not have a shake at idle, due to a worn out DMF, but it is conceivable that a very loose one could cause an idle vibration.
Installing short shift kit
Sorry. Can be deleated.
Hi, fantastic video, will get mine changed next month, I was only wondering what is that dioxide mechanical penetrant? I use wd40 professional, but I can bet this what you use I by far better 😁
Fantastic video. Thank you very much.
Maybe is just me but you were upgrading from dualmass to single mass and still used the old dualmass flywheel ? Hope my mecanic won't do that and charg me for flywheel ;)
Did you guys not watch part 2 orrrr...??
So..
A. Ask for the old parts.. say you want to look at them for interest or scrap them whatever
And
B. Watch part 2 dumb dumb
By strongest, do you mean most power? In this case, the S38 (as offered in the E34 M5) offers far more horsepower than the M50 (E36 325i, E34 525i, etc.)..
this man loves the rattler
Hi, I work on a lot of German cars and have seen a lot of these dual mass problems. We always recommend the upgrade to the 1 piece flywheel and I have one in my 2006 Jetta but I have noticed it has a very slight jerking feeling in 1st and 2nd gear when compared to a customer with a 2 piece. Have you personally noticed any roughness compared the the dual mass? It might just be me being picky
I love you for making this video.
tonycstech - The clutch disc should say either; engine side or transmission side, on one of the sides, someplace on the metal hub area. If you are using a German clutch, such as Sachs, this may be in German.
it's just a amazing and simple video! thanks for uploading :)
In general, yes, your procedures will be very similar.
well on my e34 a original dual-mass from bmw is twice the price compared to a jb-racing lightweight single-mass.
be aware tough. a single mass may create ratle whiine like noises in low rpm on bigger engines like V8. something the dual-mass is supposed to eliminate
i accidentally removed the center locking plate in the pressure plate before installing it on the car. I'm having a very difficult time reinstalling the lock plate. is it even possible to reinstall? great video by the way!
same thing happened to me, you will need to press the pressure plate springs down, then reset the smaller springs with a screw driver and hammer, there are a few vids on how to do this, just look up how to reset it, and it should work.
I also removed the locking plate before i installed the pressure plate and i installed the pressure plate anyways because it was too difficult to reinstall the locking plate. Once I reinstalled my bell housing and slave cylinder, I tried pushing down on my clutch but it would only depress about 1 to 2 inches and hangs up. Now I need to pull everything apart again. Does anyone know if it is critical to remove this locking plate after install and not before? Is this why I am unable to depress my clutch?
I just tried reinstalling the locking plate onto my old pressure plate using a large 2-jaw gear puller and a 3/4" x 1.5" x 1.5" piece of plywood for the pushing plate in the middle for the gear puller. i was successful! 😀... So now I'm going to pull everything apart again to try and reinstall the locking plate...
Please someone let me know why my clutch does not depress and if it is really critical to reset the clutch with the locking plate... I don't want to have to pull my transmission again...
i ended up dropping my transmission again yesterday. when i looked at the pressure plate, all of the fingers were fully depressed which is why i could not push down on the clutch. i then pulled off the pressure plate and followed a video on how to reset a self adjusting clutch. i built a jig, reinstalled the locking plate in the middle of the pressure plate and then while i reinstalled the pressure plate onto the flywheel with the 6 hex bolts i had to compress the springs on the self adjusting mechanism as i torqued the bolts to 35 Nm. then i popped out the locking plate and put everything back together and installed my slave cylinder. i pressed on the clutch and YES. the clutch felt normal again... man... it's a totally different procedure when you install the oem self adjusting clutch on the e46.
Can you make a video for clutch and flywheel replacement for a 2006 E60 M5 ? or is it the same process as this video ?
Thanks!
Well...., The S38 would be stronger and able to take more power than the M50, but the M50 would likely be more reliable for long term use.
You can be sure that the clutch is a SAC and the flywheel is dual-mass.
Can I borrow that neat car lift. This is extremely difficult to do in my driveway.
While a lift is certainly an advantage when doing clutch work, we've done many a clutch replacement while laying on our backs. It's not as fun, but certainly doable.
carl shneebly I am doing it right now...a pain in the a**! But it can be done...good video.
2003 530i
great work
been driving for months with a worn out clutch :\ i'll have to replace it in the next 2 months, my biggest concern (besides the cost) is whatever problems may arise when removing that piece, my mechanic said i possibly had an oil leak into the clutch and that caused the clutch do slide in higher rpm. In case of an oil leak, will the seals and gasket paste be enough to solve the problme?
Excellent videos well explained thanks for posting them the videos are a great help.
can i do it same way on N46B18?i want to install clutch set ,mine by vin is 228mm but all i find on net is 230 ,will it fit?why on other videos guys instal sac with special tool nr.212170 not only centring tool
What if you took the locking plate off of the pressure plate before installing it?
Thanks for this awesome video! I do have one question though. Do you need to support the engine in any way? I believe the E39, like my E36, has 2 mounts for the engine, and 2 for the gearbox. I just remember when I replaced the driveshaft I had to use a jack to support the gearbox. Thanks again!
great job ,video,big appreciation and like!thanks for share!
Sorry for the delay in replying. Are you still having trouble with your clutch install?
I have a 2000 BMW 528i. I was driving in trafic and it feels like the clutches "sweet spot" changed after going up a steep hill with many many many stops and starts.
You may very well have put a lot of wear on an already worn clutch. Nothing you can really do about it until you are ready to install a new clutch.
looks easy
I watched these vids before replacing the clutch in my 87 325, they were a big help, but for some reason the car wont start. just wondering if this could have anything to do with the sensors on the outside of the bell housing, I did have to remove them but I dont think they were damaged at all. I had called the number you provided but the service rep was less than helpful. Im hoping someone might be able to help me out, I just hope the same guy isnt in charge of answering the emails lol, thanx
I like the pilot bearing tool used in this video (not the slide hammer type). Where can we find it?
The fork of a BMW E36 has hand (right or left) or is indiferent?
Thanks.
Excellent video! How do I know my 2004 330ci 6-spd has a SAC? It is as 115k miles now and slipping.
One question....the rotary movement It had the dual-mass flywheel was good or not?...thanks
Hello team.
Excellent work.
Please advise: i got e46 m3 bmw. It has click noise coming from drivetrain during each gear change ( you can control the noise by clutch pedal) and rattling noise when you switch off the engine on neutral gear. However if you engage clutch during engine switch off the noise disappears. Any idea?
Thanks.
i have a question what does the bolt on the flex shield look like
I also removed the locking plate before putting it in the transmission, can that be the problem?
good work
I just installed my clutch and slave cylinder on my 99 BMW 328i. I've took it apart and put it all back together a good 6 times due to a problem I keep having with the gears. It seems now that I installed the new Pivot ball, new slave cylinder, new clutch kit and new clutch arm fork, the car goes in gears when on my ramps, however as soon as I take the car off the ramp to drive it, the car wont go in gears. I made sure to bleed the line, and the reason why i took it apart 6 times was to make sure i installed the clutch the right way, made sure the bearing was able to move, the pivot ball clip spring wasn't holding down the fork arm and moving freely. I've been looking on line to see if anyone has had this same problem in hopes of finding some feedback or a solution but have been unsuccessful in my attempts of getting any info. Do you have an idea what I'm doing wrong??
Just a small 10mm hex-haed bolt.
Nice video...
Hello!
I have a VW golf V tsi 2006. Can you please help me regarding the following issue: Today i went to an enginner for my car in order to put out the oil pan, clean it and put some paste on it to avoid oil leaking. But he made a mistake because he put a screw in the wrong place and it came in contact with the flywheel. We figured it out after we start the engine and heared a squeaky sound. He moved the car a little bit in order to elevate it and to find what happened. (The good thing is that i didnt drive my car, just a little as i described above). My question is: Should i be worried if any damaged occured to the flywheel while it came in contact with the screw? Thank you in advance
Does the crankshaft position sensor need removing? Just got my 330d E46 back and it appears to be misfiring at high revs, juddering at high revs, chucking out clouds of black smoke when wide open throttle and also throwing the DDE light when hoofing in 3rd from low revs. I've tried everything else and now suspect the Crankshaft position sensor that wasn't removed during installation has got somewhat damaged? Also get mid section vibrations at low revs full throttle......
What is the part number for the Pilot Bearing Removal Tool? I went to bavauto and found the Slide Hammer Pilot Bearing Puller CTA Tools but not the one used in the video.
just did a clutch flywheel and rear main replace and now can't get my shift linkage in my gears
Is it the same process for E60 M5 2006 ?
Just replacing clutch and not fly wheel on my 2003 m3 dosent the fly wheel need to pre loaded when installing new clutch?
After clutch was burned out and vibrations were felt on clutch pedal, i have replaced Clutch and DMF. The Cluth kit and DMF were from LUK. The workshop who replaced the parts is specialized in replacing the clutches. After replacement, i can feel vibrations on clutch pedal and also foot area ONLY when car is moving. The workshop made test drive and said it is normal and nothing to do with clutch but for me it is not and uncomfortable :( One thing i noticed that engine is a bit loud and engine vibrations are more visible in engine room. How can i get rid of them? Thanks
Unfortunately, without driving the car, we can't really give you much to go on. Have you had a different technician drive the car?
i had sam proble,den i change flywheel ...smile on my face tells all..
Can you please list all of those parts you have replaced?
That would be kind.
I'm in the process of replacing my clutch but I can't get the transmission away from the input shaft. I'm pretty sure I took all the inverted torx off, but is there a hex bolt up there also? (someone told me they thought they saw one at the top). Also, Do you have to remove the starter on BMWs? Any info will help
Is this necessary? Just had my flywheel done (E46 330D) and they didn't remove the sensor. Now I get dde light on, black smoke at high revs/WOT and juddering at high revs when this happens.......no codes on scanner though except for rail plausibility too high (too much fuel I suspect judging by black smoke). Tried everything else and now suspect timing is out. Tickover is fine though and normal driving appears ok. Slight vibration at tickover now (more like resonance). Thanks :-)
Should I renew the Bell Housing transmission bolts???
If you replace your clutch with a non-self adjusting one, does that mean you have to manually adjust it by taking the transmission out again?
No, there are no adjustments (just as with older BMWs). Over the life of the clutch, you may notice a slight change in the clutch pedal engagement position, as the clutch disc wears. Most drivers never even notice this.
BavarianAuto Isn't that what self adjusting clutches are for? Or are there performance issues with this?
Hey, I just watched your video--which is very informative. I just learned something new.
I have a problem, I purchased my 2003 BMW 325I (manual) 2yrs ago and it drove ok. But I have realized they hardly kept up with maintenance. But my problem is, my BMW does not drive like a BMW. It does not accelerate with power when I step on the gas; it feels like it struggles to move, like it drags. Basically, it does not move with power like BMW's are supposed to. What you guys know what is wrong with my BMW?
Unfortunately, we really can't make any diagnosis suggestions with the very general info you've given, and not being able to drive the car. We would suggest that you seek out a technician who is familiar with these vehicles and can make some determinations based on knowledge of what it should be running like.
Thanks for the info.
if you drive about 40 mph, in 4th gear and you step on the gas, if the numbers of revolutions are raising and you dont drive faster then the clutch has probably slippage which means you have to replace it!
Ok, I will take a look at it.
Eugene Bruno
As RoBiN noted - if the what you are trying to describe fits this description, then yes, you do have a slipping clutch.
my dad would kill me if I worked like that lol Dropping all the lug nuts and bolts
how is the car driving/during shifting after changing the clutch do you hear some sound or do you feel anything
Hi, what kind of gasket sealer or maker did you use on the steel gasket and did you use any grease or anything on the new crank seal as well?
What happens if i install a new clutch but have free play like the one on this video?
