3b crank bolt torque

[s2driveruk]

Hi just to confirm, is the torque on the bolt 350mn or 450mn, using the correct audi locking tool but need to set the bar crrectly.....

Cheers

450Nm mate, no locking agent.

for the ABY in S2Central site states that it need 200 something plus some degree! What is correct?

In my 3B manual it states that it should be 450 Nm and use some blue loctite (the one that does not require heat to loosen it).

[s2driveruk]

yep spot on Jonas, thats exactly what we did...car is almost ready to run again, just the fan to sort out now :-)

The torque is 1 Stef + a 1m scaffold bar

[s2driveruk]

Stef was out of stock that weekend so we made do with a monster 1000nm torque wrench rather than a torque wench (only jesting Stef!)

Talk wench

450nm with copper lub. doesnt now if that is the right word for it. been driving whole last year with it. and a diamond coated washer between the crankshaft and the "remhjul". (dont now the word sry)
if you use loctite you get much friction when tighting it and dont get the right torque.

[Jonas_R]

And copper lubricant does not effect the friction?

If you by copper lub. mean copper grease as you use on wheel bolts, then that would help to lower friction and thereby you would torque to much.

I'd not be copper greasing the crank bearing any time soon... if a wheel bolt can work its way loose with copper slip on it then a crank bolt sure as heck can too.

Be sparing with the loctite, you don't want the bolt ot loosen but it would be nice to be able to remove it too

[Jonas_R]

Iagree but if you use the blue loctite, then it is possible to get it off again.
