41 00... Installing Cavity Sealing (Not Expanded)

NOTE: Carry over schematic representation to the relevant vehicle type.

The following repair represents the procedure for an already expanded cavity bulkhead.

Before these work steps, prepare the new part so that it is ready to install (adapting, cutting to size, applying welding primer etc.).

Sand contact surface of cavity sealing (1) with coarse-grained sandpaper (grain 50-100).

Clean contact surface (1) with cleaning agent R2.

If necessary apply SEALANT D1 somewhat thinner on each side, to prevent the sealant from running.

Attach cavity sealing in specified position (see used part).

Fit, secure and weld up new part.
