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

Initial signs of failure may include a slight sluggishness in the tilt or tip function or minor hydraulic fluid seepage at the connection points. If left unaddressed, the hose can degrade further, leading to more significant fluid loss and a loss of hydraulic power to the cylinders. Continued operation with a compromised hose risks uncontrolled movement of the work tool.

Installation Tip

Before installing the new hose, ensure all mating surfaces and ports are clean to prevent contamination of the hydraulic system. Avoid twisting the hose during installation, as this can create stress points and lead to premature failure.

Service Note

Inspect the tilt and tip cylinders, hydraulic pump, and related control valves for any signs of wear or damage during hose replacement.
