Piston Rings
- Ensure piston ring end gap and side clearance are within specification. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
- Ensure identification punch marks on piston rings are toward top of piston. If no identification punch marks are used, piston rings can be installed with either side toward top of piston. Position piston rings at designated areas. See Fig 1 .
CAUTION:
Top compression ring must be installed so chamfered edge on inside of ring is toward top of piston.
