Equipped
by Westfalia (on the left) or as
original (on the right) the
Pick-Up serie of Bay-Window
represents approximately 10% of
the global Bus sales.

It
develops 66 hp at 4800 revolutions/mn. Its
oil capacity is of 3,5 liters. Its
crankshaft is better oiled and its valves
have a diameter of 39,3 (inlet) and 33
(exhaust). The 1700 is fixed to its box by
8 bolts, two Solex carburettors 34PDSIT
feed it. Thanks to this new engine
motorisation, the 400 meters are done en
21,4 seconds, its maximal speed being 125
km/hr and its consumption diminishes (11,4
liters/100 km according to VW !). Last,
until August 1971, the rear skirt will
have been removable. It will then be
lead-welded for this vintage. Last little
point, the master-cylinder owns two
contactors : one for the stop lights, and
one for the pressure witness-light of the
braking system. To keep it switched off,
the pressure in both circuits must be
equivalent. If everything functions
properly, the witness-light switches off
after starting.

In
August 1971, the gas trap door is
repositioned to be accessible with the
sliding door opened. At the same date, big
rear lights with backward-lights included
are appearing. The rear corners are thus
changed : the engine air inlets are wider.
For the same vintage, the driver seat is
modified to allow different positions. The
back of the seat is redesigned for a
better comfort (sides) at the front. Also,
" louvers " appear in the door panels, in
order to improve the air extraction (red
lever). Something to remember, the
presence of a diagnostic plug for the
battery with a probe for the electrolyte
level. But more generally, the global
diagnostic plug is situated at the right
of the engine compartment.

Thanks
to it, one can now diagnose 86 defaults
and this, thanks to a calculating bench.
The first results of the sales being
issued, the surprise is that the Type 2
Bay-Window is the most sold utility
vehicle in Europe. But August 1971 is a
major turn as far as the mechanical aspect
is concerned, as besides for the pick-up,
the famous 1700 Type 4 appears (boring-out
X run : 90 x 66 mm). It is accompanied by
a brake-booster. Its turbine is at the end
of the crankshaft, and its cooling case is
obviously new.
