Piston Rings

WARNING: This page is about a different variant/trim than selected.

Using inverted piston, push new piston ring into cylinder bore 0.6-0.8" (15-20 mm) from bottom. Measure piston ring end gap using a feeler gauge. Repeat for each ring. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
Clean piston ring grooves thoroughly. Install piston rings with identification mark toward top of piston. Using a feeler gauge, measure piston ring side clearance between ring and ring land.
If ring lands are excessively worn, replace piston. See PISTONS, PINS & RINGS table. Align piston ring end gaps properly on piston. See Fig 1 .
