    standard bore size should be 87-87.030mm.The wear limit is 0.20mm on top of these readings.Main bearing journals should be around 62.962mm.Big ends should measure around 49.964mm.The figures after the decimal point will not be exact when you measure them but will give you an idea what your looking for.If its not re ground have the journals polished and put a set of standard bearings in.
