Failure Symptoms

Visible fluid leaks around the seal housing are the first indication of failure. If left unaddressed, these leaks can lead to low fluid levels, causing component damage due to insufficient lubrication or hydraulic pressure loss. Continued operation with a failing seal risks significant internal wear and potential system malfunction.

Installation Tip

Always ensure the seal groove and the shaft or bore surface are meticulously clean before installation. Avoid using excessive force or sharp tools, which can easily nick or damage the seal lip during insertion.

Service Note

Inspect the mating shaft or bore for wear or damage, and check the fluid for contamination when replacing this seal.
