Two M12 threaded bores are required to install the oil level indicators GN 651; for very thin walls and fastening with nuts, two bores of diameter 12.5 mm are required. For optimal sealing with O-rings, the screws should not be too tight (max. 12 Nm). Recommended roughness of the sealing surface Ra = 3 µm. |
