    Default Big port big end (42mm) bearings wanted Newcastle

    Hi all

    I'm neck deep in an engine build and have ended up with small port bearings instead of the bigport ones that I require.

    Now I can get some during the week no problem but Id really like to maximize my attack on the build this weekend.

    So on the off chance someone in the area has a set to sell I'd be super interested

    Cheers

    Big-port B/E bearings are to suit 40mm shaft, and small-port 42mm shaft size. Or are you talking the tunnel size of the rods themselves? Big-port tunnel size is 43mm and small-port 45mm.

    ACL part numbers were 4B1710 for 40mm, and 4B1780 for 42mm.
