Connection of ignition timing stroboscope:
1 red clip to battery positive +
2 black clip to battery negative –
3 inductive prongs on ignition cable of
No. 1 cylinder
Synchronous flashing of the stroboscope
is effected with the spark in the No. 1 cyl-
inder or respectively No 12 cylinder. The
inductive prongs are clamped on to the
ignition cable to the No. 1 or No. 12 cylin-
der near the distributor. The prongs will
pick up the ignition signal an pass it on to
the strobe lamp.
D Start engine
D Direct flash lamp at vibration damper
and pointer
D Rotate distributor by hand until the
”12° before TDC” cylinder 1 or, respec-
tively, ”12° before TDC” cylinder 12
mark can be seen at the level of the
pointer edge
D Lock distributor by tightening up the
clamping screw
D Then make another check on the igni-
tion timing
Note:
Whenever the marking disc and pointer
have been taken off, they should be
adjusted again on installation with the aid
of the flywheel mark.
D Position engine at ignition TDC of cylin-
der No. 1
D Rotate engine by means of 32 mm size
ring spanner applied to hexagon at
centre of crankshaft pulley until the
measuring edge of the sight hole in the
flywheel housing is at ”o.T.” (TDC).
At this point, the rotor of the distributor
for cylinder 1-6 should be above the
notch in the edge of the distributor cas-
ing and the valves in the No. 6 cylinder
should be rocking
D Install hub with marking disc and
pointer so that the pointer coincides
with the ”OTZ 1” ( No. 1 cylinder TDC)
mark
