Hello guys,
I'm still working on my first BOSCH V8 4.0L engine rebuilt for a 2000 Discovery II. I'm done with the cleaning of the block.



I'm about to put the crankshaft back on and replace the main bearings, but before, I did take some measurements. There is no run-out on it and the diameter of the main bearing journals are inside the parameters 2.449 to 2.52 in as the overhaul manual states. My concern is with the conrod bearings journals. All of them measured in average 2.183 to 2.184 in.
On the manual the diameter for using standar bearings are 2.20 to 2.22 in and the under size 0.01 are 2.17 to 2.18 in, so I'm in the middle. Should I take the crankshaft to the machine shop and have them regrind to the undersize range or can I just use the standar bearings?

Thank you.
