– Loosen adaptor lock nut then holding gauge
with dial face directed toward you when you
are in line with the crankshaft, screw adaptor
in spark plug hole.
– Slide gauge far enough into adaptor to obtain
a reading then finger tighten adaptor lock nut.
– Since we are working with an indirect mea-
surement, ensure that dial gauge face is po-
sitioned in the same direction as the connect-
ing rod.
– Rotate magneto flywheel clockwise until pis-
ton is at Top Dead Center.
– Unlock outer ring of dial and turn it until “0”
(zero) on dial aligns with pointer.
– Lock outer ring in position.
6. From this point, rotate magneto flywheel back
1/4 turn then rotate it clockwise to reach
7.87 mm (.310 in).
NOTE:
This specification is of the type “indirect
measurement” relative to the piston movement
since we are measuring at a 45° angle through the
spark plug hole.
7. Scribe a thin mark on PTO flywheel aligned
with timing mark pointer tool.
NOTE:
This mark becomes the reference when
using the stroboscopic timing light.
CAUTION:
The static test cannot be used as a
TDC setting procedure, therefore, always check
the TDC setting with a stroboscopic timing
light.
8. Remove TDC gauge.
9. Reinstall spark plug and connect wire.
Dynamic Test
To check TDC setting, use Bombardier timing light
(P/N 529 031 900).
10. Connect timing light pick-up to MAG side
spark plug wire.
TYPICAL
1. Timing light pick-up
IMPORTANT:
To check the TDC setting, the spark
advance curve must be locked first. This allows to
perform TDC setting at
any RPM
by keeping the
ignition timing “frozen” so that it does not vary
with engine RPM. See
TDC Setting
below for
more information.
CAUTION:
If the spark advance curve is not
locked using B.U.D.S. then a wrong ignition
timing will be seen as the ignition curve does
not match the locked ignition timing.
11. Start engine and check marks
at idle speed.
Point beam of timing light straight in line with
timing mark pointer.
NOTE:
Look at the mark at the same angle as it
was scribed so that parallax error is minimized.
1. Timing light straight in line with tool slot
