Product Detail

Suction Oil Filter – Part # 803112558 for XCMG GR3505T / GR2003 Motor Graders

The suction oil filter is the first line of defense for the grader‘s hydraulic pump. Positioned on the pump‘s suction line between the hydraulic tank and the pump inlet, it removes large contaminants—such as welding slag, paint chips, and coarse debris—from the fluid before the fluid enters the pump. When this filter becomes clogged or damaged, contaminants are drawn directly into the pump, causing premature pump wear, cavitation, and eventual pump seizure—leading to loss of blade control, steering response, and overall machine operability.
