Many
of

in

include
BMW-specified
torquevalues
in
Newton-

(Nm)
and
the
equivalent
values
in

.



Digital
Multimeter

A
torque
wrench
with
a
range
up
to
about
150
Nm
(185
ft-lb)
has
adequate
capacity
for
most
of
the
repairs
covered
in
this
manual
.
For
recommended
torque
values
of
10
Nm
or
below,the
English
system
equivalent
is
given
in
inch-pounds
(in-lb)
.
These
small
values
may
be
most
easily
reached
using
a
torque
wrench
calibrated
in
inch-pounds
.
To
convert
inch-pounds
to
foot-pounds,
divide
by12

Feeler
Gauges

Feeler
gauges
are
thin
metal

used
to

.
They
are
normally
available

as
a
