Piston Rings
- Install rings with "R", "RN" or "T" mark facing upward. Some Samurai top rings are unmarked and can be installed either side upward. Position piston ring gaps. See Fig 1 . Lubricate all internal surfaces with engine oil before installation.
- Ensure arrow on piston head faces front of engine. Ensure oil hole in connecting rod faces intake side of engine. Install cylinder head, oil pick-up screen and oil pan. To complete installation, reverse removal procedure.
CAUTION:
Install spacer gap more than 45 degrees from side rail gaps. Rails should turn smoothly when installed.
