(3) Piston grooves - Fit new piston rings (2) in the piston grooves (3).
- Check the clearance for the piston ring by placing the 8H-8581 Feeler Gauge (1) between piston groove (3) and the top of piston ring (2). Refer to Specifications, "Piston and Rings" for the dimensions.
Inspect the Piston Ring End Gap
- Clean all carbon from the top of the cylinder bores.
- Place each piston ring (2) in the cylinder bores.
- Use the 8H-8581 Feeler Gauge (3) to measure piston ring end gap. Refer to Specifications, "Piston and Rings" for the dimensions.
Note: The coil spring must be removed from the oil control ring before the gap of the oil control ring is measured.
