Installation & Application Notes

Failure Symptoms

A loose or missing cap screw may initially cause a slight vibration or a minor fluid leak around the sealed joint. If left unattended, the leak can worsen, and the unsecured component may shift, leading to operational issues or potential damage to adjacent parts. The ultimate risk is component failure due to improper mounting or loss of hydraulic pressure.

Installation Tip

Always use a thread-locking compound if specified by the manufacturer for critical fasteners. Ensure the threads on both the screw and the tapped hole are clean and free of damage before installation.

Service Note

Inspect the sealing surface and any associated gasket or O-ring when replacing a cap screw.
