86 21 ... Adjusting Hood Pretension - Camlock Fastener With Spacers

WARNING: This page is about a different car, the 2010 BMW X5, 2009 BMW X5, 2008 BMW X5, and 2007 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: At least two persons are needed to install and remove the hood. Before installing and removing the hood, secure the BMW multitrailer and the entire combination against rolling. For this purpose, use the parking brake and the chocks of the BMW multitrailer.
To help adjust the hood pretension, you will need four blocks with a minimum height of 60 mm.

Installation: 

Before attaching the hood, thoroughly clean the top side of the GFP apron of the BMW multitrailer.

It is particularly important to clean the contact surface of the GFP apron (1) (marked in gray) on which the rubber seal of the hood rests. Refer to Fig. No. R86 0146Fig 1.

The following text describes how to adjust the hood pretension as an example at one support area of the platform or at one hood fastener. The pretension is adjusted at the other support areas and fasteners in the same sequence.

The hood must be fixed on the platform in such a way that the rubber seal of the hood is placed under pretension or compressed. Only with this pretension is it possible to obtain a tight seal between hood and platform. Pretension is achieved with the Camlock fasteners and by using spacers.

Two different types of spacers (2) are available for each Camlock fastener (1): one thick and one thin. You can fit one, two or no spacer (2) on the Camlock fastener (1).
