Petter A1 and W1 big end bearing shells on standard size.

Please note:- Genuine Petter or aftermarket bearings for this application are now very difficult to source, as such we have identified a bearing which is of the same physical size and readily available from another application that can be made to fit with only minor modification. You will only need to drill the oil way hole in the centre position of the plain half shell, the other half shell has an extra oil hole in it but this will not present any problem in service, it simply becomes redundant.
