As type C with dust lip
In addition to helping ignite the fuel in certain conditions, the spark plug also plays a role in maintaining the proper temperature of the combustion chamberLoosen the securing-clamp bolt at the base of the distributor, then carefully withdraw the distributor.
Step 2 Locate the spark plugs.ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
4. Look for a visible spark between the tester and the engine block or metal surface. If a spark is present, it indicates that the wire is in good condition. A reputable spark plug supplier should also offer a diverse product range to cater to various vehicle types and engine configurations. From standard spark plugs for everyday cars to high-performance units for racing vehicles, a comprehensive catalog demonstrates the supplier's understanding of the market's diverse needs.
