| Post subject: | Crankshaft nut |
Bit of a basic question but I can't see it answered anywhere - is the crankshaft nut on a 2.7 loosened in the usual anti clockwise direction? I'm trying to get mine off so I can change the belts but it won't budge, so before I apply more force or an impact wrench I thought I'd check I'm turning it the right way! |

Cheers gents. I used a big torque wrench on it and a bar extending it by another foot and still couldn't shift it - the whole car was shifting on the chassis stands rather than the nut turning, very frustrating. Plus I bent my screwdriver which I was using to lock the flywheel. |

Yup conventional nut so undo ACW. This in my view is the one special tool needed, a flywheel locking tool as it iis just too FT to undo by any of the normal bodges. |

My old 2.5' s wasn't even finger tight  Had worn a the keyway into a one about 3 times the size, no wonder it was vibrating a bit. |

I don't think I'll be trying the starter motor option, sounds a bit risky plus the starter motor is off so I can lock the flywheel (easier than going in the clutch inspection window I've found). I'll be buying a new deep 24mm socket as then I'll be able to clear the obstruction I have and get a proper lenth breaker bar on it. |

Where abouts in the country are you - I have a 3/4" drive set if you are anywhere near Leicester. |

Can an impact wrench help with this, due to the minimal torque reaction? |

I'm in Manchester but thanks for the offer! If I can't get it with a big breakers bar then I'll be purchasing an impact wrench! |

I can wholeheartedly recommend this Sealey impact wrench. Fantastic value for money, and absolutely solid: http://www.amazon.co.uk/Sealey-CP2400-C ... 451&sr=8-2
