CHAPTER 3 ENGINE PAGE. 3- 122
- must be clear of moving parts (belts, fan, etc…)
- must be protected from or kept at least 125 mm
away from radiant heat source exceeding 400 F.
- must be protected from environmental damage
(dirt, splash, oils, fluids, etc….)
- must be retained, secured or insulated to prevent
pinching, mis-routing, rattles, and squeaks
premature failure of ignition system.
DO : Not all fasteners are designed for repeat use.
Beware of fastener specifications. All harnesses
should be supported within 6" of a mating
connection.
Adequate retention force might not be achieved if the
fastener is not designed to be reused. Mating
connections are not designed to support the weight
of the harness assembly
DO : For removing spark plugs follow the following
steps:
1- Grasp the spark plug boot and gently rotate
90
; and the
cable away from the spark plug
2- Before removing spark plug, brush or air blast
dirt away from the well areas
3- Use correct size deep socket wrench to loosen
each spark plug one or two turns
To remove spark plugs from Aluminum heads, allow
the engine to cool. The heat of the engine, in
combination with a spark plug that is still hot, may
cause the spark plug threads to strip the cylinder
head
upon removal
Use goggles to protect eyes from dirt when applying
compressed air to spark plug wells
DO : Cleaning a spark plug could be done as
follow:
1- wipe all spark plug surfaces clean….remove oil,
water, dirt and moist residues.
2- If the firing end of spark plug has oily or wet
deposit, brush the spark plug in an approved, non-
flammable and non-toxic solvent. Then
dry the spark plug thoroughly with compressed
air
3- Use a propane torch to dry wet-fuel fouled
plugs. Allow the torch flame to enter up the center
electrode insulator. Allow plug to cool down
4- If the spark plug threads have carbon & scale
deposits, clean with wire brush, taking care not
- Cleaning a spark plug will reduce the voltage
required for an electrical arc(spark) across the
electrodes
- Cleaning & re-gapping will not restore a used spark
plug to a new condition. It may be more economical
and efficient to replace used spark plugs with new
plugs instead of cleaning.
- Sooted plugs should be replaced
- Do not cool by using water or any liquid
- Clean threads permit easier installation and
proper seating which will maximize transfer heat
away from the plug
