Crankshaft tolerances Kz10b

How much sideways play, should there be on the conrod, between the 2 crank halfs? 0,4mm, 0,5mm with a feeler gauge or more?
It is a TM Kz10b engine

I think it is almost impossible to find any data sheets on those engines, with torque and tolerance specs.

It is what it is when the crank is pressed and crank pin is flush within the halves

It shouldn’t be under 0.3mm or over 0.7mm
