Extremely rare to come across such an ETHICAL and professional mechanic who is also a great teacher👍👍👍 The industry needs more of such talented, honest mechanics
Mike is an absolute wizard. The amount of knowledge that he has is insane. I’ll be bringing my F80 to him very soon. Great job documenting the process guys!
The hub doesn't spin because the bolt gets loose, it spins because people tune the engine and it applies more torque than designed for. Hardly a genius, in fact dead wrong
@@ScienceBitch123 in some cases the bolt does indeed get loose over time, not just because of tuning but bad driving habits, ppl drive dct like crazy. Its bmws mistake to come up with a crank hub that would get worse stock or tune.
I DIYed mine last week with the SSR Hub. Car runs great. He is right about the 4 pin drilling process . I actually broke the supplied drill bit on the third hole. Carbide bits are strong but more prone to breaking. Ended up having to order new bits and drill that hole 1/32 bigger. If you move your hand the slightest bit while drilling it has a tendency to dig into the template and cause the hole to be slightly off. Luckily my hub went in tight with no trouble. I liked the 2 piece design because it makes it easier to get around the oil pump chain. Honestly would have considered his hub if hadn't already ordered mine. Overall not an easy DIY. You will need s55/n55 timing tools, front seal removers/installers, and a crank hub holding tool, and preferably a digital torque wrench with angle. I ended up dropping subframe on mine. I would not attempt unless you have access to a lift. Also id recommend getting BMW ISTA service guide for a day to guide through process and for proper torque values.
Kudos to you for doing this diy! What motor did you install on and what power level you at? I'm wondering, is the hub more prone to slippage on a 6mt/dct then auto? Seems like a torque converter should help this not to happen. Also wonder if any lower hp cars have ever had this issue.
@@nicholaskerlew6796 if I remember correctly I ended up buying one that was for the n55 (don’t remember if because it was cheaper or I couldn’t find a s55 one) and I drilled it to fit the s55 hub.
@@ichoozjc one year check in and my motor hasn’t blown yet lol. I was stage one bm3 when it spun but oddly I wasn’t pushing the car when it spun. Mine is 6 speed. I think the DCT is more prone to slippage
Top-notch video! I have never finished an one-hour video on TH-cam LOL This is the first one. It is so informative and interesting! Planning to get a f82 in 2 years and definitely going to take it to Precision Dynamics for this job! Nice work dude!
man I wish there was someone like him here in Ireland. Very honest with his work. mechanics here in Ireland are all cowboys. great job precision dynamics.
I love how he explained why you should change out your crank hub. Even, tho I like the fact that he said "I would like you guys to do it to" meaning us the diy guys at home. That guy sounds like me. I hope people understand that he is not trying selling you anything. But, really trying to help you guys. Love this video. Great info and love how he explained everything. As a tech I learned how not all crank hub are build the same.
Really glad that you yourself take the time to understand how and why things work in your own car. Many dudes just TH-cam base their knowledge and don’t really know what they’re doing. You are transparent and showing us that you’re willing to learn. Keep up the good content!
When doing my own rod bearings I referenced your video alot. Especially when I was getting conflicting torque specs on the rod bolts. Nice to know where all the hidden bolts and time saving tricks before starting.
I’ve been waiting for this video right when you guys started really talking about it. something about the look in your eye around other F80’s before you got yours. And I’m honestly stoked it’s an instructional DIY!
I appreciate you uploading this video. I spun my hub last week after 3 days of uploading a stage one bm3 tune and needed a good in depth diy source for the process. Luckily my car still runs and idles fine but it’s stuck in limp mode. Will be installing the ssr performance keyed hub next weekend.
Design looks great. Thanks for taking the time to film this. It's weird that BMW didn't use a woodruff key from the factory with the gears fixed. It's exactly what they were designed for 135 years ago.
Very informative, thanks for putting this together. I read that cbc should be sufficient to fix the issue because it keeps the bolt from coming out. The only ones who have reported sch with a cbc also money shifted. I’ve been running stg 2 e85 at about 550whp for about 20k miles no issues, planning on just doing the cbc.
I saw a company..MMR i think who made a one pc crank hub along with a bolt capture solution..I think if it is properly torqued and installed then it would be perfect solution because there is no way that the crank hub can spin.. I’am not bashing anyone’s solution and I have learnt a lot from this video but drilling the crank is not for me but I have learnt more in this video than I can mention..👊👊👊
Drilling the crank is risky, those pins will eventually strain under whiplash.. I think the single pc crank hub with capture from MMR is better although I will probably use this technique to install….
I like how he explains about the other crank hub designs and who installs it. So now looks like this guy knows his stuff. If I ever decide to get mine done might have to drive to cali
Just bought a F80 today with 74 k miles . Didn’t know about this crank issue. How can I ck if possible if it needs it? .. Your tech is a genius . Thx for the content..✌️✌️ All the way from Texas .
I have searched a lot, This is the best explanation for why you need to upgrade and how. Great work, appreciated. Only thing I would love to see the required replacement parts which needs to be purchased beforehand. I live in a place where it is not easy to find m3 parts so I will ship all from US. It would be great to know which part am I going to need like gasgets and etc.
I've owned 2 European mechanic shops before..from my understanding the right way to do this is to pull the engine out ,pull the crankshaft pully install the new Hub...this is a mess with shaved metals from drilling.. possible crooked drilling..top of the engine taken apart etc etc.... From Experience Mike is one of the Best Mechanics I've ever seen. Bmw should be sued to fix this problem free..just like the e90 rod bearing issues.
This video is greatly appreciated. Especially with the details on the different crankhub designs out there and what could happen if not installed correctly. Wish I was in Cali. Would definitely take my car to Precision for this.
When you were drilling the crank what precautions did you use to stop swarf dropping down into the oil sump or have you removed that too along with the subframe , steering rack etc ????
Big corporations never admit flaws or failures. Samsung, Apple, Microsoft, they all do the same shit. BMW to keep their loyal fan base fixed it because they know most BMW drivers drive their car hard…
Great video bro !!! Why not use a tested and known working design like a 2pin or 4pin Crank Hub that have been used for years ? Why use something new that has not been out in the field very long ? Doesn’t that new design throw the balance of the Crank Hub off since it has more material (key way) in that one section ?
He explained it here: 37:30 Mike's crank hub design For me, It really seems like the best design. (I have had my share of not perfectly straight drill holes) And the balance is not thrown off, since there is material on the CH itself, that rebalances things.
Problem is not their design. Problem is finding a mechanic that you can entrust to drill into a crankshaft. Drilling a crankshaft is a very delicate job. Some people even had their crankshaft crack. If you live in some poorer part of the world those guys don't even get to work on S55 often.
Did you use another locking tool apart from the pin to lock the flywheel? I've heard it's risky to remove/reinstall the crankshaft bolt without another form of locking tool... as it's too much force for the pin. Thanks
Well explained he nailed it I have a pinned crank hub on my N54 335i dam germans.... I installed it my self engine out the car its not for low level mechanics...
so just to be clear.. you're using the screwdriver to get approximate TDC position, but you get the precise TDC using the locking pin on the crank correct? (BTW probably not a good idea to use a metal screwdriver on the surface of a piston. (use a plastic rod or something to doesn't scratch)
Thanks for putting together this content! This is an awesome video that you don’t find a lot of for this depth and detail of car work. I’m learning cars more and more and am not looking for timelapse videos with music overlay
Welp Spencer has sold me to take a trip down south and get mine done at precision lol. I trust Mike to do the job with all his knowledge and expertise.

How this dude just go from having his whole business run on social media to Stop posting on every social media platform? I guess that’s how you know some crazy shit happened. Hope whatever you going through you get through it
Getting my 2018 F80 Comp 6MT CrankHub done next week. The car has 82k miles on it but I need that piece of mind 😅. Also going FBO with MHD stage 2+ on 93 Oct only.
Man my tdc pin broke off in the case hole, the flywheel hole it’s in is too big, about an inch is still sticking out, any ideas how to remove? Have intake manifold and DME outta the way but still 😢
Please tell me this is the same as the Gintani 1-piece crank hub! I literally just broke the bank for the Gintani one that I got installed last month and now I see this! Someone please tell me they're the same ffs. Help!
Yes its at 138,600 miles still no major issue , same tune....i dont do drifting and burnouts for crowds etc....just rolls when i run someone....same 100 octane tune....no injector issues that or common with e85 blends over time
Crank bolt capture plate prevents the bolt from loosening, but if you make enough power or the friction plate wears out, the gears will still spin loose
My F82 has covered 80k, and is 9 years old. For about 40k it has been running around 500 whp, for the last 10k it has had hybrid turbos and is running around 600 whp. My car has no crank hub fix. It is a manual. My advice is dont bother unless you have a DCT and/or regularly track your car. In my mind it has to be aggressive down shifts or money shifts that spin hubs. Also some of the "fixes" look like they would add more inertia, or shift the impact onto a small component that could fatigue. I cant see how adding more power alone would cause it to slip, the added load on the hub due to more boost is surely minimal. It would be over reving, or rapid changes in engine RPM that would load the hub.
The way they thype this crankhub issue is farcical . Its extremely rare to occur. Unless you tuning the engine to hell and driving like a lunatic..and then still...probably not worth it to get the fix.
I have one question. I understand the importance of the guide to drill the crank, but how do you make sure that you drill on the correct location of the crank? If the crank is drilled in the wrong spot, the timing will be off because the chain will be moved incorrectly, right? Like does the guide only fit in one location of the crank? Or can it spin? How do you know the correct location to drill. I hope that makes sense, thanks!

Do I need to do crank bolt capture in combination with the pinned hub? As there are reported pinned hub fails due to the bolt backing out!

@@jenningswinfrey8171the crankhub is not an issue..its very rare.
what is the difference between this and having a crank hub capture plate installed? Why is one better than the other?
Crank bolt capture plate prevents the bolt from loosening, but if you make enough power or the friction plate wears out, the gears will still spin loose
@@Abercrombemonkey would the chances of spin be reduced if you get this and keep the engine stock?

Can that main bolt be tightened up at regular intervals to prevent a spin?
My F82 has covered 80k, and is 9 years old. For about 40k it has been running around 500 whp, for the last 10k it has had hybrid turbos and is running around 600 whp. My car has no crank hub fix. It is a manual. My advice is dont bother unless you have a DCT and/or regularly track your car. In my mind it has to be aggressive down shifts or money shifts that spin hubs.

There is a no-drilling version out now from some tuners. What do you think about it?
I have an E90 M3, not even an F8x M3/4, and I found this fascinating. Thanks for capturing this on film with Mike.
how's the car now? that crank hub still work perfectly?
Damn with the amount of work that goes into changing out the crank hub, you might as well buy your upgrades and do it all at the same time.
I have one question. I understand the importance of the guide to drill the crank, but how do you make sure that you drill on the correct location of the crank?
If the crank is drilled in the wrong spot, the timing will be off because the chain will be moved incorrectly, right? Like does the guide only fit in one location of the crank? Or can it spin? How do you know the correct location to drill.
I hope that makes sense, thanks!
So they do this job without lowering the subframe and removing the oil pan?
