Ready to start rebuilding my rover V8 after a good clean. How to I decide if the bearings required are Standard or +10 thou ect..
I can find part numbers on old bearings but cant match these anywhere..
Thanks Paul

On the back of the bearing shell it normally says STD, +10 etc.
If there is nothing then suspect they are STD.
Measuring is the only true way.

If in doubt , take your crank etc to your local engine reconditioners /parts suppliers who should be able to measure them for you and advise
accordingly. It will be up to you to make sure the parts supplied are correct though.HTH

It's probably best to measure the current size of the crankshaft with some calipers.
I have uploaded the size information about the crankshaft here http://www.locostbuilders.co.uk/photos.php?action=showphoto&photo=crankshaft.JPG

Can't for the life of me attach it to this message.

if its standard then the mains should be 2.30 inches (2.5 inches for the 4.0L and 4.6L)and the big ends 2.00 inches diameter (tolerances for each size
should be in your haynes manual) - don't use calipers as they aren't accurate enough get your self an outside micrometer - not too
expensive and faaaar more accurate than calipers.
