Compression Check: Specifications

Measure the highest pressure reading on the compression gage.

Standard compression pressure is 1,400 kPa (199 psi) at 250 rpm.

Minimum allowable compression pressure is 1,100 kPa (156.4 psi) at 250 rpm.

IMPORTANT: The maximum allowable compression pressure difference between any two cylinders is 100 kPa (14.2 psi) at 250 rpm.
