Feeler Gauge Set
303-D027 (D81L-4201-A) or equivalent

NOTE: Use a straightedge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of length, such as Snap-On® GA438A or equivalent. For example, if the straightedge is 61 cm (24 in) long, the machined edge must be flat within 0.010 mm (0.0004 in) from end to end.

NOTE: Typical cylinder block shown.

Using the Feeler Gauge Set and a calibrated straightedge, inspect the cylinder block for flatness.
- If the measurement does not meet specification, install a new cylinder block. For additional information, refer to SPECIFICATIONS .
