You need two drillings Ø 10,5 and/or Ø 12,5 mm in the distance l 1 in the container wall. The oil level indicator can also be ins- talled directly i.e. without nut, if the container wall has a fitting thread. All individual parts necessary for the assembly are provided: set screws with the drillings for oil, hexagon nuts, O-rings and serrated lock washers for safe guard. For perfect sealing by the O-rings the screws should not be too strongly tightened (max. 12 Nm). Recommended roughness of the sealing surface R A = 3 μm.
