I believe there are 6 different bearing sizes for different tolerences, use an FSM and a Nissan dealer for proper parts.
Vernier anyone?

Use a plastic gauge to see if you need to replace them and to see your tolerance when installing new ones. Sometimes the bearing journals get warn on crank.
Vlad make sure you know a little more before you attempt motor rebuild. You can ask me don’t be affraid. Call me up, I’m ussually up your way in the evenings anyway, we can grab a coffee.

correct, and ‘we’ are ‘calling’ them bearings because that is what they are.
You will also need to replace your rod bearings too while youre at it.
Generally you can tell by looking at the bearing if it needs replacing or not. If it is scored/scratched/burned. Get new bearings. They are not that expensive dude.
