Name: 1183134 Cylinder Gp-Blade — Cat 550 550b
Brand: CAT
SKU: 1183134
Availability: InStock

This is a blade cylinder group, a hydraulic actuator responsible for providing the force to lift, lower, and angle the machine's blade. It is engineered to operate under high hydraulic pressure, ensuring precise and powerful blade control, unlike a worn cylinder which may exhibit slow movement or leaks. Operators may notice the blade not holding its position, moving sluggishly, or leaking hydraulic fluid.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

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 initial symptom of a failing blade cylinder is often slow or jerky blade movement, or the inability to hold a set position. If ignored, leaks will worsen, leading to a loss of hydraulic pressure and complete loss of blade control. This can prevent effective grading and potentially cause damage to the blade or surrounding components.

Installation Tip

Thoroughly flush the hydraulic system with clean fluid before installing the new cylinder to remove any contaminants. Ensure all hydraulic connections are tightened securely but avoid overtightening, which can damage the fittings.

Service Note

Inspect hydraulic hoses, fittings, and the hydraulic pump for leaks or signs of wear when replacing the blade cylinder group.
