To install an oil seal properly, the shaft must be undamaged. This is so the oil seal can do its job properly on the one hand, and to prevent it from being damaged during fitting on the other. In addition, it is very important to lubricate the shaft, the sealing lip and the bore with plenty of grease. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. The oil seal may also come into contact with the keyway, thread or other grooves when sliding over the shaft. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.

Prepare the shaft and prevent damage
In addition to these standardised types, the following special types are also available:
J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.
When it comes to replacing spark plugs in your car, cost is always a factor to consider. New spark plugs can vary in price depending on the brand, material, and quality. It is important to understand the factors that contribute to the cost of spark plugs in order to make an informed decision.
Minor lip The minor lip prevents the entry of dust and contaminants from outside.
Lubricant can be retained in the space between the main lip and the minor lip.
■Dispersants: This is your oil’s magic ingredient. It gives your oil the ability to absorb and hold solid contaminants so that they don’t damage the engine.

In conclusion, auto parts oil seals, including the 99 Camry oil pump seal, are essential components in vehicle systems, contributing to the efficiency, performance, and reliability of automotive systems. Understanding the significance of these seals and their proper maintenance is crucial for optimizing the performance and longevity of the vehicle.
Functions
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.
