The glow plug must be able to withstand high temperatures, high
FR
pressures, vibrations and attack of corrosive agents which develop
during the combustion.

The tip of the glow plug must be positioned very precisely to
ignite the fuel. In fact it should not penetrate too deeply into the
ES
combustion chamber as it may trigger the combustion incorrectly.
For these reasons, the replacement is problematic and the glow
IT
plugs easily break in their seat.
• Specifications for use:
PT
Dimension A ≥ 14 mm (M10)
Dimension A ≥ 20 mm (M9, M8)
Dimension L ≤ 13 mm

The use of this equipment requires attention and care in
DA
positioning on the axis of the glow plug to avoid problems on
the head and to avoid the risk of breaking the tools; it can be
helpful to use as reference the inclination of adjacent glow
EL
plug (small differences: ± 5 ° are not significant for the final
result).
IMPORTANT - During the drilling phase with
two-diameter drill (for the removal of the upper
threaded part of the glow plug), to preserve
the quality of the drill and increase its duration,
follow absolutely these notes:
-
MAX number of revolutions: 200 revolutions/min
-
After a few mm of drilling depth (1÷3 mm), remove the
drill and lubricate with cutting fluid, blow the seat of the
glow plug to remove the metal shavings.
-
Carry on the drilling phase in this way till the complete
removal of the threaded part of the glow plug.
