Piston Rings
- Place ring into cylinder bore. Using a piston, push ring into smallest part of cylinder bore. Measure ring end gap. If ring end gap is too large, use an oversize ring. If ring end gap is too small, file material from end of ring. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
- Measure clearance between piston ring groove and piston ring. If clearance is not within specification, replace piston. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS. Position piston ring gaps in proper areas. See Fig 1.
