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 first sign of a failing quick coupler is often increased play or looseness between the machine and the attachment. If not addressed, this can lead to difficulty in securing implements or, in severe cases, accidental detachment during operation. Continued use risks damage to the coupler, the implement, and potential safety hazards.

Installation Tip

Thoroughly inspect the machine's hydraulic and locking pin systems for any damage or wear before installing the new coupler. Ensure the locking pins engage smoothly and fully without excessive force.

Service Note

Inspect the hydraulic lines and seals connected to the quick coupler system for any signs of leaks or wear.
