Choose a suitable centring piece (3).
Note: The diameter of the centring piece tip must
be identical to the diameter of the glow plug
electrode.
Rotate the centring piece (3) onto the guide bolt
(4).
Select the requisite screw tap (6, 7, 8, 9 or 10),
slide it onto the guide bolt (2) and lightly oil the
screw tap.
Insert the centring piece with the guide bolt into
the electrode slot and check for proper fit.
Rotate the screw tap clockwise with an
appropriate ring spanner / open-end wrench and
cut a new (larger) thread into the glow plug slot.
Remove the screw tap by rotating anticlockwise.
Please note: Leave the centring piece and guide
bolt in the slot! Otherwise chips can get into the
combustion chamber and lead to engine
damage.
Please note: Wearing protective goggles for the
following work is mandatory!!
Push the centring piece with the guide bolt into
the slot by hand, cover the screw tap with a cloth
and blow out the glow plug slot with compressed
air.
Check the glow plug slot for any remaining chips
and blow out again if need be.
Rotate a suitable thread insert (11, 12, 13 or 14)
onto the mounting bolt (2) and mount into the
thread cut earlier.
Remove the mounting bolt and mount a new
glow plug.
