A Comprehensive Guide on How to Replace Crankshaft Seal

Crankshaft seals, also known as oil seals, are crucial components in your vehicle’s engine. They serve a dual purpose: preventing oil from leaking out of the engine and keeping dust and dirt from entering. Over time, these seals can wear out and require replacement to maintain the engine’s performance. This article will guide you through the process of replacing both front and rear crankshaft seals. As a leading mechanical parts factory, Sanping Machinery offers a wide range of high-quality seals, including the 14589129 boom cylinder seal kit and the 14589140 arm cylinder seal kit.

Understanding Crankshaft Seals

Before diving into the replacement process, it’s essential to understand what crankshaft seals are and their role in your vehicle’s engine. These seals are typically made of rubber or metal and are designed to fit around the crankshaft’s ends. They form a tight seal that prevents oil from leaking out of the engine while also keeping dirt and other contaminants from entering.

At Sanping Machinery, we offer different types of oil seals, including the popular LBH seal and the skeleton oil seal. These seals are designed to withstand high pressure and temperature, ensuring a long-lasting seal.

How to Replace Front Crankshaft Seal

The front crankshaft seal is located behind the main pulley of the engine. To replace it, you’ll need to remove the serpentine belt and the main pulley. Once these are removed, you can access the seal. Use a seal puller to remove the old seal carefully. Before installing the new seal, clean the area thoroughly to ensure a tight fit. Apply a thin layer of oil to the new seal and press it into place using a seal driver. Reinstall the pulley and the serpentine belt.

Choosing the Right Replacement Seal

When replacing your crankshaft seal, it’s crucial to choose a high-quality replacement. A poor-quality seal may not provide a tight seal, leading to oil leaks and potential engine damage. At Sanping Machinery, we pride ourselves on offering high-quality, durable seals that you can rely on. Our range includes the 14589129 boom cylinder seal kit and the 14589140 arm cylinder seal kit, both of which are designed to provide a superior seal and long-lasting performance.

How to Replace Rear Crankshaft Oil Seal

The rear crankshaft oil seal is located at the back of the engine, where the crankshaft connects with the transmission. Replacing this seal is a bit more complex as it requires removing the transmission. Once the transmission is removed, you can access the seal. Use a seal puller to remove the old seal and clean the area thoroughly. Apply a thin layer of oil to the new seal and press it into place using a seal driver. Reinstall the transmission.

Sanping Machinery, a trusted floating seal supplier, offers a range of high-quality seals, including the PC 200 travel motor seal kit. This kit includes all the seals you need to replace the rear crankshaft oil seal.

How to Replace a Front Main Seal

The front main seal is another name for the front crankshaft seal. The process of replacing this seal is the same as described above. It’s important to note that when replacing any seal, always use high-quality replacement parts. Sanping Machinery, a leading China piston seal manufacturer, offers a range of seals that are designed to provide a superior seal and long-lasting performance.
