Ted,better measure those crank journals again. it should be under the 32 mm size down to 31.97.What manual are you using? in the Honda manual no reference is given to the codes on the case, i normally measure the bore of the case. But the Haynes manual does refer to the case codes. i have used them in the past and have not had any problems. ( i still double check with the bore measurements)Kevin
Something wrong with your measuring, need another 0 and plastigauge is more reliable. Never seen 4 different shells on a crank ever
Ted,Can you see the crankshaft markings? A and 1 in this example. (Attachment Link) Ignore the red circles.
You could mic the green shells with a small bar inside the arc in same direction as crank goes, then do the same for the "mystery" shells to get some view of a match or not.Put a metal bar (thinking silver steel as it's ground to diameter, or similar) in a vice, lay the shell over it and mic the two together to get accurate reading.
I had the same issue with one of my crankshafts, only a couple of markings visible. I took my crankshaft to an engineering company I knew and had the crankshaft measured. As Trigger stated all the measurements were identical.
"Not sure how to use Plastiguage to help with identifying 1 & 5."Likely that these two are going to be at least Brown to then check with plastigauge.
