Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most common initial symptom is a visible leak of lubricant from the sealed area, often appearing as grease or oil around the component. If not addressed, the leak will worsen, potentially leading to insufficient lubrication and accelerated wear of the protected components. Failure to replace the seal can result in premature component failure due to contamination or lack of lubrication.

Installation Tip

Thoroughly clean the bore and shaft where the seal will be installed, ensuring no dirt or debris remains. Press the seal in squarely and avoid using excessive force, which can damage the seal or its housing.

Service Note

Inspect the mating shaft or bore for wear or damage, and clean the lubricant reservoir and passages.
