Default Over-tightening stretch bolt

Hi,

Fitting the crankshaft damper center bolt, I remembered the stage 2 angle wrong and did 180 degrees instead of 90! How bad is this? I've backed it out to about 120 degrees now, but should I get a new bolt?

Thanks

I'd say if nothing snapped let it be. It's bloody tight as it is, right?
But if you ever have to take the damper off again, then make sure to use a new bolt.

If I recall correctly the crank bolt gets 60 degrees of angle torque. So you got that very tight on there. If it didn't break I'd second Jan's suggestion to leave it be. Just have a long breaker bar or impact for removal when you do your next timing belt. Plus a new bolt.

Hi,

According to VIDA it's 110Nm + 90degrees.

For peace of mind, I picked up another bolt. I think it would have nagged me forever, if I hadn't.

Thanks

Okay, the S/V/C prefix points at your 2014 V70 SE (UK specs?).
What's the "D4" part?
Maybe it uses the same bolt as your (I assume presumed by others) 240, maybe not.
The specs could be wildly different, depending on the engine (sorry... motor?) fitted.

D4 is the engine.

Definitely not the same bolt as a 240.

Can't figure out if that's sarcastic or not, but 110 000 miles and no sign of smoke so far.

Yeah, inflection is hard to convey. I meant that sarcastic as you suspected. I always thought it was kind of dumb of Volvo not to offer those engines here in a large market. The diesel they did sell here wasn't made by them and then when they do make their own diesel they don't sell it here.
