    • The wiper ring has a small shelf.

    • Position the smaller diameter of the wiper ring on the bottom of the wiper ring groove, so that the smaller diameter is closer to the oil ring, and the larger diameter closer to the top surface of the piston.

    • This shelf functions to pull oil off of the cylinder wall during the downward strokes of the piston.

    • Push the cylinder onto the upper piston until all piston rings are compressed by the cylinder wall.

    • Make sure to keep the cylinder supported so the piston is not supporting the entire weight of the block.

  31. MiTM Air Compressors AM1PH6508HD 2012 Piston Rings Replacement: passo 31, imagem 1 %32 MiTM Air Compressors AM1PH6508HD 2012 Piston Rings Replacement: passo 31, imagem 2 %32 MiTM Air Compressors AM1PH6508HD 2012 Piston Rings Replacement: passo 31, imagem 3 %32
