41 00... Installing A Cavity Acoustic Baffle (Expanded)
The following repair represents the procedure for an already expanded cavity bulkhead.
The cavity bulkhead remains on the body in this instance.
Before these work steps, prepare the new part so that it is ready to install (adapting, cutting to size, applying welding primer etc.).
Clean contact surface (1) with cleaning agent R2.
Apply a bead (2) approx. 15 mm high of SEALANT D1 to contact surface (1).
In order to avoid run off of the sealant when bonding to a vertical surface, a thin coat of sealant on both sides of the surface may be necessary.
Fit, secure and weld up new part.
