Aftermarket cranks are famous for having a large radius.They make narrow rod bearing for them.As said I had a slight issue with a rear main when I took a engine down.The very back was in the brass but nothing like this.Was never enough to even feel it when the crank was turned without the seal.Just something to be aware of when using aftermarket cranks.When I got there today all the caps were off.Im sure the seal was toast with the heat that crank and bearing saw.Tom
