    Flywheel nut /// Big End bearing

    I wonder should i undo the M12 X1 nut anticlockwise as any other nut or clockwise ?

    And does anybody know which is the code number of the big end bearing ?

    I am doing a bottom end rebuild so i am sure will come back with a few more questions

    Big end bearing only comes with a conrod kit because they wear as one. Along with the crank pin.

    I have a feeling that he ment main bearing though?

    Bang on there are 3 bearing surfaces

    1Crank pin
    2Big end bearing
    3Conrod

    All 3 wear at the same time so all 3 need to be changed, That is why they only sell a full kit
