Shop HITACHI EX120-1-2-3-5 OIL TANK FILTER SPRING | Tonkee®

Maintaining Filter Element Position: The spring keeps the filter element securely in place within the oil tank, preventing it from moving or shifting during the equipment's operation.

This ensures that the filter can effectively trap contaminants from the hydraulic fluid.

Tensioning: The spring provides the necessary tension to keep the filter element pressed firmly against the filter housing. This contact ensures that hydraulic fluid must pass through the filter, allowing for efficient filtration and the removal of particles and impurities.

Preventing Collapses: Hydraulic systems experience pressure fluctuations during operation. The spring helps prevent the filter element from collapsing under these pressure variations, maintaining a consistent flow of oil through the filter.

Extended Filter Element Life: By supporting the filter element and preventing it from being dislodged or damaged, the spring contributes to the longevity and effectiveness of the filter element. This, in turn, helps protect the hydraulic system from contaminants that could cause wear and tear.

The oil tank filter spring's significance cannot be overstated, as it plays a crucial role in maintaining the hydraulic system's health and performance in HITACHI EX120-1-2-3-5 excavators. Here are some key reasons why this component is essential:

Contaminant Removal: Hydraulic systems rely on clean and uncontaminated oil to function optimally.

The oil tank filter, with the support of the spring, ensures that contaminants like dirt, debris, and metal particles are effectively removed from the hydraulic fluid. This protects vital components from damage and extends their lifespan.

System Efficiency: Proper filtration leads to smoother and more efficient hydraulic system operation. Clean oil reduces friction and wear, resulting in improved performance, reduced downtime, and lower maintenance costs.

Preventative Maintenance: By safeguarding the filter element, the spring helps prevent costly breakdowns and repairs. Regular maintenance and replacement of the oil tank filter and its spring can significantly extend the excavator's service life.

Operator Safety: A well-maintained hydraulic system enhances operator safety by ensuring the equipment responds predictably and reliably to control inputs. Unfiltered or contaminated oil can lead to erratic operation and potential safety hazards.
