Replacement of PUR bonded windows on 850

The window is among other things also a vital support for the passenger airbag. To ensure proper bond the Volvo PUR kit of type 2K (P/N 1161381-7) must be used.

To ensure a good bond when replacing bonded windows, all bonding surfaces on the body must be prepared with RIM activator P/N 1161373-4. This applies in cases where there are mixed adhesion surfaces including paintwork (intermediate layer or topcoats) or PUR residue where the surface has been scraped clean. RIM activator ensures PUR bonding for all combinations of bonding surface and can be used instead of applying several different types of activators.

Note:
If parts or all of the body flange have been painted a paint primer must be used as usual according to the Service Manual for the newly painted surfaces. Where there are both newly painted and original surfaces both primer and RIM activator must be used for the respective surfaces.

RIM activator is best applied with the felt brush supplied in the PUR bonding kit. RIM activator evaporates rapidly, a window is ready for bonding within approx. 2 minutes.

Note:
Check the expiration date on the PUR bonding kit. Check both the package and the tubes of adhesive. Do not use PUR materials that have expired. On the packaging it may state a "Best before:" or "Use before:" date. The "Best before" date should be treated as the expiration date.

Note:
When applying a PUR bonded windshield to the body it is important that the PUR adhesive does not come into contact with the spacers located at the upper edge which the windshield is supported by, or there is a risk that water will leak by the spacers.

Note:
A new lower windshield trim strip without butyl tape, P/N 9154227-4, has been introduced on cars with chassis numbers from 117958 (854) and 27006 (855). If the windshield is to be replaced on cars with lower chassis numbers than these be absolutely certain that there is not old glass or other material in the butyl tape on the trim strip. If there is then the strip must be replaced with a new one or the new windshield could crack.
