Review NATIONAL Output Shaft Seal Kit For Gmc Manual Transmission fits EX 1965–1966

Introducing the National SX-Q7BT Shaft Seal Kit, a must-have component for the maintenance and repair of 1965-1966 GMC I2500 manual transmission trucks. Designed to fit specifically with the ex model, this seal kit provides a perfect replacement for worn-out or damaged seals, ensuring a reliable and efficient drivetrain.

The SX-Q7BT kit includes all the necessary shaft seals required for the transmission's output shaft, tailshaft, and propeller shaft. Each seal is meticulously engineered using high-quality materials, such as precision-cut gaskets and durable rubber seals, to provide an optimal seal against oil, coolant, or transmission fluid leaks.

The output shaft seal, located at the transmission's bell housing, is designed to prevent oil leakage around the shaft. This seal features an O-ring groove that ensures a proper seal between the shaft and the bell housing when installed correctly.

The tailshaft seal, positioned between the transmission and differential, protects against fluid loss while also providing an effective barrier against contaminants. This seal consists of a high-performance rubber material that can withstand the harsh conditions of the drivetrain.

Lastly, the propeller shaft seal, located at the end of the propeller shaft, is responsible for preventing fluid leakage and maintaining the driveline's integrity. The seal's design ensures a snug fit around the shaft, creating a tight seal and preventing potential leaks.

Installing the National SX-Q7BT Shaft Seal Kit is a straightforward process, with each seal designed to fit easily and securely into place. However, it is essential to follow the correct installation procedures to ensure that the seals are properly seated and that all O-rings and gaskets are correctly positioned.

By investing in the National SX-Q7BT Shaft Seal Kit, you are not only ensuring the longevity and reliability of your 1965-1966 GMC I2500 manual transmission but also preventing potential damage caused by fluid leaks. Trust National to provide you with the highest quality components, backed by their commitment to customer satisfaction.
