4. InSTRUcTIOnS
nOTE: To minimise the possibility of damage to the engine, it is
advisable to remove the cylinder head from the engine prior to
commencing work of this nature. The tap guide system
included with this set will significantly reduce the ingress of
swarf/debris into the combustion chamber and cylinder.
Always wear eye and hand protection when cleaning any
swarf/debris from the engine. A full range of personal safety
equipment is available from your Sealey Dealer.
4.1.
Repairing a damaged thread using a tap
WARnInG! Ensure you have read, understood and apply
Section 1 safety instructions.
4.1.1. Determine the size of the thread to be repaired. This can be
done by carefully using the insert drivers to compare with the
thread of an undamaged glow plug aperture.
4.1.2. Using the correct size of tap and insert guide, assemble the
set as shown in fig.2 and fig.3.
4.1.3. If a ring spanner is to be used, position on the tap before
inserting the insert guide pin into the glow plug aperture. Apply
a layer of general purpose grease to the insert guide to help
prevent swarf/debris from entering the engine and place into
the glow plug aperture.
4.1.4. Hold the knurled head (17) and position the guide rod (16)
so that the insert guide pin is squarely positioned in the glow
plug aperture.
4.1.5. Using a spanner with adequate downward pressure, carefully
run the tap down the damaged thread 1/2 of a turn forward
then 1/4 of a turn back to repair the damaged thread. Always
use a suitable cutting fluid. Periodically remove the tap and
insert guide to clean away the swarf/debris. Apply a layer
of general purpose grease to the insert guide before
re-inserting into the glow plug aperture. Continue until the full
length of the thread has been repaired.
nOTE: It is very important to clean away as much swarf/debris
as possible during the thread cutting process to avoid any
ingress into the engine.
4.1.6. Once the thread has been repaired, ensure that all swarf/
debris has been completely removed and carefully fit the
glow plug.
4.1.7. Ensure all tools are removed from the engine bay and stored
away. Store in a safe, dry, childproof location.
