- The performance of a spark plug is influenced by several factors, including its design, material composition, and heat range. The design of the plug determines its ability to withstand high temperatures and pressures without failing. Materials such as iridium and platinum are used in high-performance spark plugs due to their excellent resistance to heat and wear.
- Make a thorough inspection of surfaces in contact with oil seal
- Conclusion
- Spark plugs are designed with a central electrode and a side electrode, separated by a tiny gap. When voltage from the ignition system jumps this gap, it creates a spark, which in turn ignites the compressed fuel and air inside the cylinder. This ignition triggers a controlled explosion, driving the piston down and ultimately turning the vehicle's wheels or performing whatever task the machine is designed for.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
d1-d2, mm - A double oil seal, also known as a tandem seal or a dual seal, consists of two sealing elements placed in series. This design offers a two-layered defense against contamination ingress and fluid egress, thereby enhancing the overall sealing performance. The primary seal acts as the first line of defense, while the secondary seal serves as a backup, providing redundancy in case the primary seal fails.
Longer seal life can be expected with shafts having a Rockwell (RC) hardness of 30 or more. When exposed to abrasive contamination, the hardness should be increased to RC 60.

1. Follow the instructions in the manual
There may be a rubber '0' ring oil seal round the base of the distributor, or a paper gasket under the plate of the securing clamp. Remove either seal, clean away all dirt and oil, and fit the new one.
