4-Stage Air Cleaning System

Rock crushing operations can generate significant amounts of dust, particularly when processing quartz, dry ore, and mineral-bearing rock.

The 4-stage air cleaning system is designed to help protect the engine by reducing the amount of airborne dirt and debris entering the intake system.

Benefits of a properly maintained air filtration system include:

• Helps reduce dust entering the engine

• Supports reliable engine operation in dusty working conditions

• Helps minimize premature wear caused by airborne contaminants

• Provides additional filtration for demanding outdoor applications

• Supports routine engine maintenance and longevity

Maintenance Tip: Inspect and service the air cleaner according to Kohler's recommendations. Rock crushing environments may require more frequent air filter maintenance than cleaner operating conditions.

Why Replace Your Rock Crusher Engine?

A dependable engine is essential for maintaining consistent operation of your gas-powered rock crusher.

Over time, heavy use, dusty conditions, and normal mechanical wear can affect engine performance.

Common reasons for replacing a crusher engine include:

• Excessive engine wear or mechanical damage

• Difficulty starting or maintaining normal operation

• Reduced power under crushing loads

• Expensive repairs to an aging engine

• Damage to internal engine components

• Restoring an older K&M crusher to working condition

Replacing a damaged engine with a compatible unit can help extend the service life of your existing crusher without replacing the entire machine.

Installation & Safety Recommendations

1. Confirm that the replacement engine matches your crusher's required specifications.

2. Verify the engine mounting pattern, output shaft, pulley fit, and drive alignment.

3. Follow Kohler's instructions for engine installation, lubrication, fueling, and initial startup.

4. Ensure the engine is securely mounted and the drive belt is correctly aligned and tensioned.

5. Install all required guards and protective components before operating the crusher.

6. Follow the manufacturer's recommended maintenance schedule.

Important Safety Information:

• Gasoline engines produce carbon monoxide. Never operate indoors or in enclosed spaces.

• Allow the engine to cool before refueling or performing maintenance.

• Keep hands, clothing, and tools away from moving belts and pulleys.

• Use appropriate dust control and respiratory protection when crushing rock.

• Never operate the crusher without properly installed safety guards.

• Follow all Kohler engine operating and maintenance instructions.
