V
f
REGULAR
MAINTENANCE
General
On
the
TR.6
the conventional
carburation
system
is replaced
by
a
fuel
injection
system.
-
This
system
delivers
precisely metered
and timed
quantities
of
fuel,
in
the form
of
a
fine
spray, to
the air intakes
via injectors.
The
mixture
is
then
compressed
and spark ignited
by
conven-
tional means.
Th9
design
of the
equipment
used
is
such that
all
adjustments,
with
the
exception
of the
slow running
described
on page 54,
should
be
undertaken
only
by the
skilled
engineers
employed by
Triumph
distributors
or dealers.
Routine
maintenance
is restricted
to changing the fuel
filter
elcrnents
(see
page 51)
and
a unit
overhaul at 36,000 miles
(60,000
km.)
which must
be
carried out by the Triumph
distributors
or
dealers.
