- Step 5 Install the new spark plugs.
- Moreover, the 7mm spark plug wires are designed to withstand high temperatures and mechanical stress, making them more durable and less prone to degradation over time
7mm spark plug wire. Their robust construction contributes to a longer lifespan, reducing the need for frequent replacements and maintenance costs.


Lubricant can be retained in the space between the main lip and the minor lip.
In terms of size, oil seals are available in a wide range of dimensions to suit different shaft diameters and housing sizes. It is crucial to select the correct size seal to ensure a proper fit, as using an improperly sized seal can lead to leaks and premature wear.

If oil is dripping down your motorcycle’s tube, your vehicle’s performance will be affected. It won’t have as much power, and you’ll notice it acting sluggishly.
The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.
Various materials with unique properties are utilised in the construction of rotary shaft seals, allowing manufacturers to tailor the sealing solution to specific industry requirements and ensure optimal performance.
