- In conclusion, testing a spark plug is not just a mechanical task but a diagnostic tool that provides a window into the health of your engine. It's a simple yet effective way to keep your car running smoothly and efficiently. Remember, prevention is always better than cure, and a well-maintained spark plug is key to a happy and healthy engine.
- After installing the new spark plugs, reassemble any components you removed to access them. Start the engine and listen for any unusual noises or vibrations. Take the vehicle for a test drive to ensure that the engine is running smoothly and that there are no misfires.
Some aspects to consider when selecting this component are:
Types of oil seals
Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.
The hardness of the shaft determines how long the seal will last. A shaft should have a Rockwell hardness of 30 or more. It prevents the seal from getting damaged when it’s exposed to abrasive agents.
- lubricant, such as performance, can be in 204 ° C (400 ° F) long-term work under high temperature. Although
- Sex is good;
a) The shaft on which the oil seal is to be mounted should be ground with the surface finish or surface roughness between 0.2 to 0.8 Microns. It is best for the shaft to be hardened atleast to 40 – 45 HRc in order to prevent groove formation on the shaft due to the pressure exerted by the spring.

The advantages are low friction and minimum power consumption, the possible use even in case of insufficient lubrication, operating range of -130º c to +200º c and much more: high chemical resistance and a low breakaway torque after standstill. Further, the PTFE, when heated, can” remember” its original form and return to it (phenomenon known as” plastic memory effect”).Therefore, this kind of seal do not need the old school metallic spring.

The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth.Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
