In order to secure quality gluing of the frame upon the rear bumper, make sure that the
surrounding working temperature ranges between 15 – 30°C during the whole time of
gluing the frame and during subsequent reticulation of the glue. Make sure the parts
will not be exposed to direct solar radiation.
During the fitting, provide for the ventilation of the workplace – the de-greasers
contain dangerous vapours.
Fitting procedure
- Fix the vehicle upon the arms of a workshop jack.
-
Remove the rear bumper (including dirt strainers if the vehicle is provided
with them), the beam of the rear bumper and the ventilating covers.
(see Bodywork and fitting jobs – group of repairs 63)
-
Loosen the lining of the rear mud-guards.
Advice: After removing the beam of the rear bumper, add anticorrosive
protection in the points of contact between the bumper and the bodywork. The
places without anticorrosive protection with bare zinc-coated sheet metal are to
be sprayed twice (min. 25 microns) with anticorrosive filler in spray (Spray Max
1K Acryl Füller). Let the filler dry for about 20 min. at a temperature of about
20° C, and apply preservation wax in spray.
Cutting out a hole in the rear bumper
- 4 -
-
Put the removed rear bumper upon a soft felt surface by its inner side upwards.
- Using a suitable tool, mark the centres for drilling four holes in the points of pre-
stamped axial crosses -arrows-.
- 5 -
-
Drill holes of the diameter of 10,5 mm in the marked points. Use a drill for metal
sheets (angle of the main cutting tip 180°).
Be careful to place the holes precisely.
- 6, 7 -
Fit the prepared punching tool upon the rear bumper in the following way.
-
Fit the cutting board (M) upon the lower supporting board (L) with the blade
upwards (towards the bumper).
- Fit this set upon the outer (painted) side of the bumper in such a way that the screws
may pass through the drilled holes.
- From the inner side of the bumper, fit the pressing board (N) upon protruding
shanks of the screws.
- Tighten the complete set slightly by the nuts M 10 (P) with the washer (O).
Be
careful to avoid a damage to the painted side of the bumper.
Check the position of the assembled punching tool visually. If needed, adjust its
position slightly with respect to the lower edge of the bumper, in scope of the play
among the screws and the pre-drilled holes in the bumper.
