Shop manual for the 5740 (turbocharged) shows NO piston cooling jets either. So where are they? Nobody has been able to show me that any Kubota has them. None of the parts pix show piston cooling jets on any of their engines.
Dealer dyno proved this machine and showed me it was within 5% of advertised. I have not checked timing, another good point. The dealer simply gave me all the hoopla that this machine is what it is, an unbroken, working properly unit. It's mine now, I'll deal with it.

I believe they are a part of the block so they will not show as as a separate part as they do on other engines.
