180-5938 Piston Motor Seal Kit — Cat 3013 3013C

This piston motor seal kit is designed to prevent leakage and maintain proper hydraulic pressure within the piston motor system. Manufactured with durable sealing materials that resist wear and hydraulic fluid degradation, it ensures optimal performance compared to a worn kit that would lead to leaks and reduced efficiency. Operators may notice a loss of power, erratic motor function, or visible hydraulic fluid leaks as signs of a failing seal kit.

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

A failing piston motor seal kit will typically first present as a noticeable hydraulic fluid leak from the motor housing. If ignored, this can lead to a gradual loss of hydraulic power and slower, less responsive motor operation. The worst consequence is potential damage to the hydraulic pump or system due to low fluid levels and contamination.

Installation Tip

Thoroughly clean all internal and external surfaces of the piston motor before installing the new seals. Ensure all seals are properly seated and lubricated with clean hydraulic fluid to prevent tearing during installation.

Service Note

When replacing the piston motor seal kit, inspect the motor's internal components for wear and ensure the hydraulic fluid is clean and at the correct level.
