Information

- Lightly grease the O-rings on the three outer lines on the turbocharger using Kluber Syntheso Glep only.

- The O-rings on the oil pressure lines must not be greased. Only apply a light coating of Kluber Syntheso Glep on the bore in the turbocharger.

Information

We recommend that you use the following tools to secure the internal Torx screw (oil pressure line) on the turbocharger:

- Torx screwdriver insert bits Nr.41 (Hazett 2223 lg T30).
