[Saloon-lovers] Problems with brand new front windscreens

Yesterday I had a shop install a new Pilkington screen on
a 420G (The label said it was manuf in 2006 but it has
been on a shelf with a parts company since).
It is simply too wide. This prevents the rubber seal from
sitting flat against the glass on the outside, at both
short /side ends. The edges have a 45deg lift which
theoretically could be filled with black ‘‘stuff’’. Ugly but
doable, BUT this prevents the chrome surrounds from
correct placement.

Back home, I checked with the other G which has its
original 1967 Triplex screen. Beautiful and perfect
installation with new SNG seal after a repaint last year.
What I also see when looking at the car from 1m to the
sides, is that the original one has a different profile.
It has a somewhat bulbous/concave shape which the new
Pilkington screen lacks. It is very flat.

All ideas and suggestions welcome…!!!
I doubt that anybody but Pilkington make screens for these
old cars. What happened to Triplex?

or could it be that the seal from SNG is too short? But I
doubt it as an identical seal was used 2yrs ago on the other
G with its perfectly fitting original windscreen.–

Peder,

Who fitted it?

The manuals all say that the body may need to be filed to ensure
that there is a wide enough gap all the way around for the rubber.

If the glass is the correct shape for the car, but the rubber is
pinched then it may not lay flat.

But offering up the glass to the body before fitting it would
normally reveal a problem with either the shape of the glass, or
the gap.

Automotive screens can be cut with a waterjet, but it isn’t cheap.
(I know that George D�nni has had this done here in CH.)

there was talk on the e-type forum about mis-fitting
Pilkington front screens I believe, some time ago?

The fellow that has the 3.8 MK10 in Spain fitted a new
Pilkington after breaking his original

at that time, a discussion was had about seals being wrong
profile, but no complete agreement was had.

I always obtain glass from any wrecks I pick, even though
its a huge b!tch to store, breaking any window on these cars
can be problematical

recently after whipper-snippering, I noticed my daily driver
had a shattered rear screen, a thrown rock will shatter
rears or side!

No rear or side glass is available new for zeniths–

If it is a triplex screen,it can be ground on the sides for
fitting. If hardened ,one cannot adjust it.

Thanks Andrew,
D�nni fitted a new screen to my black E which cracked on
the way home, about 13 mins after I left his place.
And after other issues, I stopped using him.
The car has had a good screen, with perfect fit, for the
last 8 yrs.
Why can�t Pilkington get that original, handsome,
bulbous/concave shape…?
Interesting about filing the body to increase the open
area for the screen. Never heard that before.
Agree with someone on keeping old screens, but have to say
that when driving with the sun against you, the visibility
is hampered by the old age, ‘‘millions’’ of small spots and
a few stone chips, wiper scratches etc.
Prepared to take that for a perfect fit, including those
tricky chrome surrounds, which are so difficult to keep in
place as they only have one rubber lip to keep them in
place, whereas the smaller saloons have narrower chrome,
held in place with 2 rubber lips.

Thumbs up for original screens!
I have 2 cars (Mk10 and G) with original screens, and they fit absolutely beautifully in all aspects. The chrome halves sit perfectly and with a bit of caulking against the body, it looks like it came right ouf of Browns Lane. And both windscreens have been out for body painting in one case and new rubber seals in both cases. A 3rd car had the trouble with the new Triplex being too wide, and now has a new, but transport scratched (lightly) hardenend screen. The chrome half pieces sit sort of ok, but certainly not as good as on the other two cars.
And being hardened they will of course leave million of small glass parts in the car if broken. I am not entirely happy about this. Maybe I should try the filing of the A pillars as suggested by Andrew, and give the Triplex screen another chance, with a new seal.

Peder, an article in last month’s Jaguar World magazine discussed new E-Type windshield from Pilkington not fitting, and neither did a replacement. It seems it’s a common issue. All FYI.
