2 Use a feeler gage (0.04 mm) to inspect permissible variation.
It must not be possible to insert the feeler gage (0.04 mm) between crankcase contact surface (1) and knife-edge straightedge (2). If the inspection is carried out in the transverse direction, the permissible variation stated is merely a reference value and cannot be measured.
