Might be in the UK but not in Aus (or at least haven't heard of it ever being checked) |

It is but only if it is clearly 'visible and identifiable' but in any case, the OP won’t have to worry about UK mot regulations.

& NSW has the toughest regulations in the country. If it doesn't blow too much smoke the car is ok & if the arduous braking test is better than the oldest road registered car in NSW which has leather brakes, your car gets a pass! A South Australian road registered car which is a touch behind on its auto detailing. Their rear window seemed to have just been stolen!

I think a new bolt is highly recommended.

I've never bothered with using a new bolt.

The crank pulley bolt is a stretch bolt, which needs renewing whenever it's been removed.

Bolt snapped or came undone? I suspect that the requirement for a replacement bolt might be due to the fact they come with a dab of loctite already on them rather than genuinely being torque to yield (70Nm is not near the recommended max torque of a grade 10.9 M14 bolt at 150Nm). If I do have to reuse it will definitely loctite it on. |

@perko, I suggest you re-read the manual. Crankshaft pulley bolt torque is 70Nm + 82°. (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.

A bolt is specified for one use only if... a) It has loctite pre-applied and/or b) It's designed to permanently stretch (ie plastic deformation) when torqued. You don't want to reuse b), because you have to stretch it even further to get to the torque the second time, which it wasn't designed for. I do reuse some bolts (apply loctite) but it's hard to know whether they are a) or b) (or both). Bolts on large rotating parts are more likely to be b). If the consequences of failure would be high, I'll just spring for the new bolt. Flywheel bolts, and end bolts on crankshafts and camshafts come to mind. |

You're missing the +82° rotation, after the initial torque. This is what pre-loads the bolt, allowing it to stretch, which is why its a single use bolt. Hyundai Ioniq 5 Ultimate.

Agreed, it's hard to know which it is, to be honest I don't really see the reason for using torque to yield in this type of application, a primary driver for cylinder head bolts being TTY is to reduce changes in clamping force during expansion. Plenty of crank bolts with big torque specs though so I guess some are. I am aware of the additional angle requirement (note the use of an angle doesn't always imply the bolt is being loaded past the elastic limit) and will get a new bolt however I'm still a bit sceptical that it's TTY, will compare the new bolt to the one removed and see if it's possible to measure a difference. |
