Would anyone be kind enough to have a flick through their haynes manual and check what the oil clearances are for the main and conrod bearins the crankshaft?

Thanks!

The link takes me to your photo page, there's 2 photos I believe are the ones I'm after but they're too blurry for me to make out

I found clearances for the 893, which may be the same as 919

Main bearing: 0.0007 - 0.0014"
Con Rod: 0.0012 - 0.0020"

If these are the correct figures, then there doesn't seem to be a plastigauge product that does the size of the main bearing clearances, the smallest one they do is 0.001 - 0.007" (red/orange box)
This is fine for the rod bearings and at the top end of the main bearings.

I also read somewhere that its the green plastigauge that I need, 0.007 - 0.02" but that's 'way' over range.

Or am I getting myself muddled up somewhere?
