LC50V00006F1 STRAINER, SUCTION

Product Overview

The LC50V00006F1 Suction Strainer is a critical hydraulic system component for Kobelco SK200-8, SK210LC-8, and SK250-8 excavators. This suction strainer, also known as a hydraulic pump inlet strainer or tank suction filter, is mounted inside the hydraulic tank at the suction port of the main hydraulic pump. Its primary function is to filter hydraulic oil before it enters the pump, capturing contaminants that could otherwise cause serious damage to precision pump components.

The Kobelco SK200-8, SK210LC-8, and SK250-8 are 20-26 ton class excavators powered by the Hino J05E engine . These machines feature sophisticated hydraulic systems that rely on clean oil for reliable operation. The suction strainer is the first line of defense in the hydraulic system, removing debris and contaminants before they can reach the main hydraulic pump and other sensitive components.

This strainer works in conjunction with the hydraulic return filter to maintain system cleanliness. According to Kobelco’s service documentation for the SK200-8, the suction strainer is listed as a key component in the hydraulic oil tank filtration system . A clogged or damaged suction strainer can restrict oil flow, leading to pump cavitation, reduced hydraulic performance, and potential pump failure. Replacing a worn or damaged strainer with this OEM-spec LC50V00006F1 component restores proper filtration and flow.

How the Suction Strainer Works

The suction strainer is positioned at the lowest point of the hydraulic tank, submerged in the hydraulic oil. It is attached to the suction pipe that leads to the main hydraulic pump.

Filtration Process

1. Oil is drawn from the hydraulic tank through the suction strainer

2. The strainer’s mesh captures debris, particles, and contaminants

3. Filtered oil passes through the strainer to the suction pipe

4. Oil flows to the main hydraulic pump for pressurization

5. Clean oil circulates to control valves and cylinders

Importance of Proper Filtration

The main hydraulic pump has extremely tight tolerances. Even small particles can cause:

• Scoring of valve plates and pistons

• Premature pump wear and failure

• Reduced hydraulic efficiency

• Contamination of the entire hydraulic system

Related Components

According to Kobelco service documentation, the SK200-8 hydraulic system uses multiple filtration components :

Signs Your Suction Strainer Needs Service

The suction strainer should be inspected and cleaned or replaced when you observe:

1. Pump Cavitation Noise: Unusual whining or knocking sounds from the hydraulic pump, especially at startup or under load.

2. Sluggish Hydraulic Response: Slow implement operation or reduced digging power, indicating restricted oil flow.

3. Visible Debris: During inspection, the strainer mesh is covered with debris, metal particles, or sludge.

4. Damaged Mesh: Tears, holes, or deformation of the strainer mesh that compromises filtration.

5. During Scheduled Maintenance: Inspect the suction strainer at recommended service intervals.

6. After Pump Failure: When replacing a failed hydraulic pump, always clean or replace the suction strainer.

7. Hydraulic Contamination: After contamination events, inspect and clean the strainer.

8. Reduced Hydraulic Performance: General loss of hydraulic power or response.

Benefits

Why choose our LC50V00006F1 Suction Strainer for your Kobelco excavator?

1. Protects the Main Pump: The hydraulic pump is one of the most expensive components on the excavator. The suction strainer is the first line of defense against contamination damage.

2. Prevents Pump Failure: Captures debris that would otherwise damage precision pump components.

3. Maintains Hydraulic Performance: Clean oil flow ensures proper hydraulic response and digging power.

4. Extends Component Life: Clean oil circulating through the system extends the life of all hydraulic components.

5. Cost-Effective Maintenance: Reusable design allows cleaning and reuse during routine service.

6. Essential for System Cleanliness: Works with the return filter to maintain overall hydraulic system cleanliness.

7. OEM Fit Guarantee: Manufactured to match the original mounting and flow specifications.

8. Prevents Contamination Spread: Captures debris before it can circulate through the system.

Installation Tips

• Professional Installation Recommended: Suction strainer service requires draining hydraulic oil and accessing the tank interior. Professional installation is recommended.

• Drain Hydraulic Oil: The hydraulic tank must be drained below the suction strainer level before removal.

• Clean Work Environment: Work in a clean area to prevent contamination from entering the hydraulic tank.

• Inspect the Tank: While the strainer is removed, inspect the inside of the hydraulic tank for debris or sludge.

• Replace the O-Ring: The strainer sealing O-ring (ZD11G19000) should be replaced whenever the strainer is removed .

• Inspect for Damage: Check the strainer mesh for tears, holes, or deformation. Replace if damaged.

• Proper Seating: Ensure the strainer is fully seated in the suction port before securing.

• Refill with Clean Oil: After service, refill the hydraulic tank with clean oil of the correct grade.

• Bleed the System: After installation, properly bleed air from the hydraulic system before operation.
