cannot remove crankshaft nut on Vauxhall Vectra 2.0DTi on a 53 reg plate

Discussion in 'Vectra' started by Graham Brooker, Nov 5, 2010.

  1. The front pulley on my Vauxhall Vvectra 2.0DTi flexible rubber mount has
    sheared (well known problem) and my mechanic is having difficulty removing
    the crankshaft nut that holds the pulley in place. Vauxhall tech support
    tells him to keep persevering with his air powered breaker wrench designed
    for a lorry (he burnt one out and had to replace it). They say it is a
    normal RH thread and it could take hours of work with an air tool to loosen
    it as it tightens up in use and has a locking fluid holding it in place. He
    does not want to heat it as it would damage the oil seal and pump behind.
    He is scared to freeze the crankshaft end as it could weaken the metal. He
    is worried about whacking it with a long bar on the wrench.

    Has anyone got any ideas. Graham

    Chewck the nut isnt LH thread, some of the japanese cars have different
    threads. I own a Holden Barina and i found 3 nuts on my car with LH threads.
    Check your service manual just to be sure.
