Fit the new gasket to the cover or head — whichever the old gasket was fixed to.
The dimensions of the 25x47x7 oil seal refer to its inner diameter, outer diameter, and thickness, respectively. These measurements are important in ensuring a proper fit for the seal in the machine or engine it is intended for. By providing a secure seal between moving parts, the oil seal helps to maintain proper lubrication in the machine and prevent the loss of oil.


As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
In addition to these standardised types, the following special types are also available:
(5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.
Stuff clean rags into the cylinder bores and all water and oil passages and bolt holes to catch scrapings and dirt.

Spark plugs and wires are essential components in the ignition system of internal combustion engines. Spark plugs play a critical role in igniting the air-fuel mixture within the engine cylinders, initiating the combustion process that powers the vehicle. High-quality spark plugs and wires are crucial for ensuring efficient fuel combustion, optimal engine performance, and reduced emissions. As a result, the quality and reliability of spark plugs and wires directly impact the overall efficiency and environmental impact of the vehicle.
