Rear Screen (Cemented), Replace

Models 39, 49

Replacement using Thermo-Knife MKM-590-A is described below.

Replacement is also possible using Wire Cutter MKM-589.

Observe safety instructions!

Remove

Remove screen trim strip. Remove fixers.

The strip is not in contact with the cement.

Remove inner trim panel of window pillars.

Cover inner panelling of rear end panel with paper to protect it from any cement dropping down before cutting using the Thermo- Knife.

Disconnect electrical contacts of heated rear screen and remove rear screen (using MKM-590-A).

Cutters:      MKM-590-4 (lower edge of screen)

                  MKM-590-3 (upper and side edges of screen)

Ensure sufficient ventilation for exhaust gases from the cement in the working area.

Observe manufacturer's instructions.

Remove rear screen from body frame (2 mechanics required).

Trim off remaining cement bead down to a thickness of 1 mm/0.04 in.

Remaining bead serves as a base for new cement.

Keep cement bead free of dirt.

Use MKM-590-A with Scraper MKM-590-5.

Do not overheat cement bead.

Note:

The new cement bonds with the cut cement without any loss of quality.

Where cement remains are burned no new cement should be applied. (Loss of adhesion occurs.)

Install

The cementing kit available from P & A is to be used for cementing in the screen.

The kit consists of:

1     Polyurethane cement

2     Cleansing solvent

3     Glass primer

4     Glass primer applicator

5     Cleaning cloth

6     Sponge

7     Application nozzle

8     Cutting wire

Place screen on holder (commercially available).

De-grease edge of screen with cleansing solvent (A).

Apply glass primer "B". Area approx. 15 to 20 mm/0.6 to 0.8 in. wide.

Shake primer for 1 minute before application.

Allow primer to set slightly for approx. 5 minutes after application.

Do not get dirt on primer area.

Fingerprints lead to, for example, loss of adhesion.

Place screen trim strip (ring band) on edge of screen.

Seal lip of trim strip is flush with upper side of screen.

Apply cement to screen.

       The cementing kit contains a triangular nozzle according to illus. D 1923.

       Before cementing, apply a test bead to check bead diameter.

Use Air-Powered Gun MKM-592 or commercially available cartridge pistol for cement cartridges.

Adhesion and sealing of the screen are dependent on the thickness of the bead.

Working temperature approx. 20° C/68° F.

Ensure sufficient ventilation in the working area.

Install fixers for adjustment of screen height.

Note identification; L = left and R = right.

1     Fixers

2     Rivet bolts (guide for fixer on body)

Place rear screen in body frame (2 mechanics) and press lightly.

Use Rubber Suction Holder MKM-641.

The cement is completely set after approx. 36 hours.

The vehicle can be driven 2 hours after completion of cementing.

Do not heat cement (no hot sunlight, radiators and drying kilns).

The cement is hardened by air humidity.

       If necessary, moisten the cemented screen all around approx. 10 minutes with water.

Note:

Before cement is completely set, close doors, luggage compartment lid. Close sash windows and sun roof when driving.
