730403000395 Hydraulic Return Filter for Sunward Excavators (63x114x450mm)

   The 730403000395 filter is a critical "kidney" for your Sunward machine’s hydraulic system. Due to its significant length (450mm), it offers an exceptionally high dirt-holding capacity, which is vital for large excavators (such as the SWE series) that operate under heavy duty cycles. The microglass media is designed to maintain structural integrity even during cold starts when hydraulic oil viscosity is high and backpressure increases.

Q&A Section

Q1: How often should I replace the 730403000395 hydraulic filter?

A: Standard intervals for Sunward machines are typically every 500 to 1,000 operating hours. However, if your machine's monitor shows a "Return Filter Clogged" warning or the bypass indicator is in the red zone, replace it immediately to prevent unfiltered oil from circulating.

Q2: Can I clean and reuse this filter?

A: No. The 730403000395 uses high-efficiency synthetic media that traps particles deep within the fibers. Washing it will damage the structure and allow contaminants to pass through, potentially causing thousands of dollars in damage to the hydraulic pumps.

Q3: Does this filter include the bypass valve?

A: Usually, the bypass valve is built into the filter housing on the machine, not the element itself. When replacing the 730403000395, ensure the spring-loaded valve in the housing is moving freely and not stuck open.
