@Stacy82 does it make any noise at idle and dipping the clutch? Or is it when the cars moving and you press the clutch?
If it’s the latter it’s the bearing on the mainshaft failing I would say.
Eh, there’s no need for that is there! There was no slurring of words last night. Not to the extent of last Friday anyway. Mchopter - see! I can type it, just not necessarily say it when I’m a good few jägers in 👀
Ok so flywheel is bolted to the crank, the clutch cover is bolted to the flywheel, so when you redline it with the clutch depressed, you will still be spinning the gearbox input shaft. That’s normal, but I wouldn’t be revving it like that at a standstill personally.
Gears feeling notchy is...
Nope. But it’s obviously now become internet folklore.
The only N57’s I’ve seen have been police vehicles. And that’s because they spend the majority of their life sitting in a lay-by at idle, then when mr/mrs criminal come smoking past, they go from 0 to tasty and it didn’t do them any...
Trust me mate, the noise is very distinctive.
Interestingly enough though, the fault codes that the M3/M4 display when the motor fails wouldn’t actually lead you to the valvetronic motor! Lol!
Oh and @FatRS listen for a ticking noise from the top end of the engine at idle. It sounds like a...
So I’ve seen more valvetronic motor failures than I’ve seen crank hub failure! Granted, no ones going to necessarily bring a modified M3/M4 into a main dealer, but I’ve never seen a standard spec crank hub failure. Remapped? Yep. And BMW see it in the data that’s transmitted back to them, so...
Not sure at the moment mate tbh. Yeah so without those nylon pads on the fingers, you’ll get movement at the gearstick and the selector hub will start machining the brass fork eventually.
What diff are you replacing it with? Once he sees it, it should become more than obvious. Heating up the...
I’m looking at making some replacement forks in steel that will do away with the brass original with the nylon fingers. It will also be stronger. The crownwheel will press off, but only really needs doing if you’re fitting a LSD.
Nope I’m afraid not.
You can get a bolt in plate off eBay that...
There’s a few calculators online that will give you a definitive answer.
I used one when I geared my cup for the Nordschliefe. Swapped out the 5th gear for a meg 5th and went up from 15’s to 16’s. End result was 153/154 (on the limiter) iirc on the straight running down to Schwedenkreuz...
If the service manual told you to line the clutch up with your c**k, or your finger, would you do it?
My experience tells me that it creates problems as it collects clutch dust and stops things moving freely. All greases have different properties as well - not a one size fits all scenario.
That sounds like clutch drag then as it’s not allowing the shaft to slow down. That in turn hammers the synchros as they have more work to do in slowing the gears down.
Did you put any grease on the input shaft splines at all? For possibly the first time ever, you’re better off going in dry...
