CAT312C Blade Cylinder Seal Kit Description

The YNF17029 Blade Cylinder Seal Kit, replacing OEM 170-9946, is engineered for the CAT 312C excavator blade cylinder, also used in certain swing-related hydraulic mechanisms. The blade cylinder operates under heavy load, continuous cycling, and exposure to dirt and debris, making seal quality essential for reliable hydraulic performance. When seals wear out, the machine may experience oil leakage, weak lifting capability, jerky movement, or complete loss of control pressure.

Manufactured using premium PU, NBR, PTFE, and composite wear-resistant materials, the YNF17029 kit ensures excellent sealing performance, reduced friction, and long working life. Every seal is precision-engineered for accurate OEM fitment and consistent operation, even under demanding jobsite conditions.

This kit is trusted by excavator repair shops, equipment rental fleets, and aftermarket resellers for restoring cylinder efficiency, minimizing downtime, and extending machine life.
