General Procedure

NOTE: Use care when fitting piston rings to avoid possible damage to the piston ring or the cylinder bore.

NOTE: Refer to General Specifications in the appropriate engine service information for the specification.

NOTE: Piston rings should not be transferred from one piston to another.

NOTE: The cylinder bore must be within specification for taper and out-of-round.

Use a piston without rings to push a piston ring in a cylinder to the bottom of ring travel.
Use the Feeler Gauge Set to measure the top piston ring end gap and the second piston ring end gap.
