Carefully lift off the cover. If it sticks, gently tap it sideways with a soft-faced rawhide or nylon hammer, or with the heel of your hand.

2. Oil seal structure and functions
Introduction
The numbers 30-50-10 indicate the dimensions of the oil seal, specifically its inner diameter, outer diameter, and height. This measurement ensures that the oil seal fits perfectly into the designated space and effectively seals off any potential leaks.
A spark plug ignition coil plays a crucial role in the functioning of an internal combustion engine. It is responsible for generating the high voltage needed to create a spark within the combustion chamber, igniting the air-fuel mixture and initiating the power stroke. Without a properly functioning ignition coil, the engine would not be able to start or run efficiently.
Why do I have to install my Oil Seal this way?
A wide range of sealing devices are used in various machines.
Sealing devices serve the following functions:
Aluminum alloys and resin (materials with a large difference between the linear expansion coefficients) demand sufficient consideration (as there is a risk of failure due to the increased clearance with the oil seal at high temperatures).
