- To ensure reliable performance for heavy-duty vehicles, it is essential to use high-quality spark plugs that are suitable for the specific engine. Regular maintenance, including inspection for damage and checking the engine's compression, is also vital to maintain the spark plugs' effectiveness and prevent engine damage. By following these practices, truck owners can keep their vehicles running smoothly and efficiently, reducing the risk of breakdowns and extending the life of the engine.

- 2. HVAC Systems In HVAC systems, molded gaskets are used to seal ductwork, air handlers, and other components to prevent air leaks and maintain optimal indoor air quality.
- * Design The 35x47x7 oil seal features a radial lip design, which creates a tight seal between the moving parts of the machinery and prevents oil leaks
Table 8 shows the housing design checklist.
Seal type - 5. Refill the engine with oil and coolant.
- The front hub oil seal is an essential component of any vehicle's wheel assembly. Its primary function is to prevent the lubricant from leaking out and contaminants from entering the hub, which could potentially damage the bearings and other internal components.
- The B20 series valve cover gasket plays a critical role in maintaining the integrity of the engine. If the gasket fails or becomes damaged, oil can leak out, causing a reduction in oil pressure and potentially leading to engine damage. Additionally, a faulty gasket can allow debris and contaminants to enter the engine, further exacerbating the problem.
Silicone (VMQ) Oil Seals
Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.
High mileage oil is specifically designed for cars with more than 75,000 miles. This type of oil can help reduce oil consumption, minimize leaks and oil seepage, and can also help reduce smoke and emissions in older engines.


Oil seals close spaces between moving or stationary mechanical components to prevent lubricants like grease and oil from escaping, while also preventing dust, dirt, moisture, and other contaminants from entering the seal. Also known as shaft seals, dirt seals, lip seals, or grease seals, the primary components of any oil seal include an inner metal ring, which provides structural support, and a spring, which provides interference for effective sealing.
Why do I have to install my Oil Seal this way?
Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
Why Is Bearing A Seal Important?
Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failure
