LE11P00011F1 Air Filter Assy

Product Overview

The LE11P00011F1 Air Filter Assy is a critical engine protection component for the Kobelco SK75-8 excavator equipped with the Isuzu 4LE2XCUA diesel engine. This complete air cleaner assembly ensures that only clean, filtered air enters the engine’s combustion chambers, protecting internal components from abrasive dust and debris.

The Kobelco SK75-8 is a 7.5-ton class compact excavator widely used in construction, utility work, landscaping, and rental fleets. It is powered by the Isuzu 4LE2XCUA engine, a 4-cylinder, 2.179-liter turbocharged and intercooled diesel producing 42 kW (57.14 hp) at 2,200 rpm . This engine meets Tier 3/Stage IIIA emissions standards and requires clean air for optimal combustion and long service life.

The air filter assembly typically consists of the filter housing, the primary (outer) filter element, and the secondary (inner) safety element. Working together, these components prevent airborne particles from entering the engine intake. A clogged or damaged air filter can lead to reduced engine power, increased fuel consumption, excessive black smoke, and accelerated wear of piston rings, cylinder liners, and turbocharger components . Replacing a worn filter with this OEM-spec LE11P00011F1 assembly restores proper airflow and engine protection.

Why Air Filtration Matters for the SK75-8

The Isuzu 4LE2 engine in the Kobelco SK75-8 is a precision diesel powerplant with tight tolerances. The engine’s direct injection system, turbocharger, and emissions control components all depend on clean air for proper operation.

What Happens Without Proper Air Filtration

Service Recommendations

According to industry maintenance guidelines for the Kobelco SK75-8, regular replacement of the engine air filter is essential for maintaining machine reliability . The air filter should be inspected periodically and replaced when the restriction indicator shows a red signal, or as recommended in the operator’s manual. Operating in dusty environments may require more frequent changes.

Signs Your Air Filter Assembly Needs Replacement

The air filter assembly should be inspected and replaced when you observe:

1. Restriction Indicator: The air filter restriction indicator (if equipped) shows a red signal or the yellow section is fully visible.

2. Reduced Engine Power: The engine lacks power under load, struggles to reach full RPM, or accelerates slowly.

3. Excessive Black Smoke: Dark exhaust smoke indicates restricted air flow and incomplete combustion.

4. Increased Fuel Consumption: A clogged filter reduces fuel efficiency as the engine compensates for restricted air.

5. Visible Damage: The filter housing or element is cracked, torn, or damaged.

6. During Scheduled Maintenance: Replace the air filter at the manufacturer’s recommended service interval.

7. High Operating Hours: If operating in dusty conditions, replace the filter more frequently than standard intervals.

5. Direct OEM Fit: Engineered to match the original mounting and connection points for straightforward installation.

6. Complete Assembly: Includes housing and filter elements for a comprehensive replacement.

7. OEM-Quality Assurance: Manufactured to meet or exceed original equipment standards for filtration efficiency.

Installation Tips

• Professional Installation Recommended: Air filter replacement is a relatively straightforward procedure, but proper care must be taken to prevent contamination from entering the intake system.

• Clean the Housing: Before installing the new filter, wipe out the inside of the air filter housing with a clean cloth to remove accumulated dust.

• Inspect the Intake Hose: Check the air intake hose for cracks, looseness, or damage that could allow unfiltered air to enter.

• Check the Restriction Indicator: If your machine is equipped with an air filter restriction indicator, inspect it for proper function.

• Secure All Clamps: Ensure all clamps on the air intake system are tight after installation to prevent air leaks.

• Replace Both Elements: If the assembly uses primary and secondary elements, replace both simultaneously.

• Record Service Date: Note the replacement date and operating hours for future maintenance planning.

• Check for Proper Seal: Ensure the filter seals properly in the housing to prevent dust bypass.
