BE provides bearings with such a tolerance and then the dealer pairs them (up and down)? ** the "risk" is that you can get the wrong tolerance if the dealer did his job irresponsibly?? am I right? |

BE "bin" (arranging the shells according to measured size, some are a little thicker, some are a little thinner)) and "pair them" (putting together two and two that combined result in a specific total thickness). All the dealer have to do is to not mix them up but to mount the pairs as they come delivered.

This video was off to me. I respect Evolve and their products but don't agree with their position that this is a 'serviceable item' and putting OE bearings back in.

So are BE bearing unavailable at all during this time? Is there an estimated time when they will be readily available again?
Looking to do rod bearing over the winter here on my track car and trying to decide what to go with. BE was likely the first choice, but if they aren't available then I need to figure out which brand to go with instead.. |

ACL std shells are aimed at achieving the std BMW nominal clearance (which, if you're unlucky is too tight). That said, I have seen anecdotal reports (offhand I recall 1 set measured by BE, a couple of dozen or so installed by Redish motors in the UK), they end up being bigger clearances than BMW shells. ACH HX shells have extra clearance, but it is considered a little too much, even going by high performance engine industry norms. So hence mixing and measuring the std and the HX ACL shells to achieve the ideal clearances. 911r Have you got a better photo than that? That one's a bit blurry TX and Scharbag Fair point, and I did ask Abdul if he could record measurements, which he agreed too, but of course you could argue he made them up unless he shows a video of it being done, or photos? What would convince you guys it was done legitimately? [edit] I guess this would be your answer.. Quote:
deansbimmer Would you be willing to sell me a set of mixed and measured ACL shells to me? I'm in the UK. If you are, how much would that be? And do you sell ARP 2000 bolts? (not bothered if their 'BE' ones or not).

, and as a result I decided to order the BE ones for my s65. as for me the ACL seams to be not optimal decision with its risk to be in OEM nominal clearance, as you said above. but, nevertheless, in Ukraine BE is not popular bearings for s65/s85 such as in USA, almost everyone change OEM for OEM. ** sorry for my English, its not perfect) Quote:

1. "These also limit crankshaft bearings clearances.... 2. ..... have a positive effect to the oil flow rate" as a result - worn out bearings(( |

... " limit crankshaft bearing clearances over a greater temp range.... "
As a positive to oil flow... ? BMW knows something we don't

These things are damn hard to photograph well...
2012 LCI E92 M3 with 107K miles. After all the scaremongering on here and having passed 100K miles I figured I should replace these. Evidently changing the oil every 7K miles is well worthwhile. £1600 I didn't need to spend, but at least I now have peace of mind. The worst one is probably from Rod #7, so I've taken a close up of that one. Practically no wear at all. To be fair I did have an engine seize on me at 33K miles. That car died whilst I was driving the salesman to pick up another car as it was on my way home. I'd only had it for 10 minutes, and had just got it warmed up, when I experienced what one might call "heavy engine braking" changing into 3rd gear at 8000rpm, coasting to a stop in a convenient lay-by about 100 yards short of where I was dropping him off. Fortunately my mechanic was nearby test driving a very nice, somewhat older, BMW he'd just serviced and popped by to advise me to call recovery! You can see the poor salesman in the photo below, slowly turning pale before giving me back my money. Picked up the current car, again with 33K miles on it, three days later, so it all turned out OK!
