NOTE

Use the battery which is fully charged.

Special Tools - Compression Gauge, 20 kgf/cm²: 57001-221 Compression Gauge Adapter, M10 × 1.0: 57001-1601 L-Shape Hose [C]: 57001-1606

Cylinder Compression Measurement


Cylinder Compression Usable Range: 1 099 1 668 kPa (11.2
17.0 kgf/cm²,
159 242 psi) at 320 r/min (rpm)


The following table should be consulted if the obtainable compression reading is not within the usable range.

Problem Diagnosis Remedy (Action)
Cylinder compression is higher than usable range Carbon accumulation on piston and in combustion chamber possibly due to damaged valve stem oil seal and/or damaged piston oil rings (This may be indicated by white exhaust smoke). Remove the carbon deposits and replace damaged parts if necessary.
Incorrect cylinder head gasket thickness Replace the gasket with a standard part.
Cylinder compression is lower than usable range Gas leakage around cylinder head Replace damaged gasket and check cylinder head warp
Bad condition of valve seating Repair if necessary.
Incorrect valve clearance Adjust the valve clearance.
Incorrect piston/cylinder clearance Replace the piston and/or cylinder.
Piston seizure Inspect the cylinder and replace/repair the cylinder and/or piston as necessary.
Bad condition of piston ring and/or piston ring grooves Replace the piston and/or the piston rings.
