259-7346 259-7346 — Cat

This component is a high-quality seal designed to prevent leakage in critical fluid systems, such as hydraulics or transmissions. It is manufactured to meet stringent CAT specifications, ensuring reliable sealing performance and longevity, unlike a worn seal that can lead to fluid loss and contamination. Operators may observe external fluid leaks, notice a drop in system pressure, or experience a gradual degradation in equipment performance when this seal begins to fail.

Failure Symptoms

The first sign of failure is typically a visible fluid leak from the sealed component or assembly. If left unaddressed, the leak will likely worsen, potentially leading to insufficient fluid levels and increased wear on internal parts. Continued operation with a failing seal risks significant damage to the system and costly repairs.

Installation Tip

Thoroughly clean the bore or shaft where the seal will be installed, checking for any burrs or damage that could compromise the seal. Use a proper seal driver or appropriate tool to install the seal straight and square, avoiding cocking it in the bore.

Service Note

Inspect the fluid level and condition, and check for any signs of contamination in the system when replacing this seal.
