Maintenance Tips

Maintain Your Eagle Crusher Regularly for Highest Production and Maximum Profitability

CAUTION: Always Lock Out/Tag Out the Power Supply Prior to Any and All Maintenance.

Engine Fluid Levels

Check and maintain the engine fluid levels (oil, coolant, etc.). Check, clean or replace the engine air filter as necessary. Monitor and maintain the proper concentration of the Coolant Additive in your cooling system. Testing for normal levels is typically achieved by using a test kit obtained from the parts department at your local engine dealer.

Oil Levels

Check the oil level site glasses of the vibrating feeders and screens, if or where applicable. Drain and refill regularly per the recommendations in your Operator’s Manual.


Inspect the inside of the impactor on a daily basis. Look for worn or damaged blow bars and replace or turn if necessary. Look for worn, damaged or missing curtain and side liners. Replace as necessary. Assure that all blow-bar wedges and spindle pins are in place.

Belt Drives

Inspect belt drives for damage or loose belt tension. Replace cracked, glazed, torn or separated belts. Maintain proper belt tension for optimum performance of your plant. Loose or worn belts and sheaves can affect the generator speed and result in low voltage supply to all electric-powered components. Low voltage can cause electric-motor and electric-panel component failures. Consult the manual for belt-tension calculation procedures.

Leveling the Plant

Check the plant for level. Side to side level is more critical for proper operation than front to back level. Adjust the hydraulic legs as necessary to bring the plant into a level position from side to side at both ends of the plant. Always insert the pins in the leg tubes so that the pins support the plant and not just the hydraulic cylinder itself. Allowing the plant to “lean” to one side causes incorrect oil levels in feeders and screens. This can cause oil to run into the center tubes of the feeders and can cause seal leaks to develop in both the feeders and screens. Allowing a plant to operate out of level also causes uneven wear patterns on the blow bars and curtains inside your impactor.

Blow Bars

Flip or replace blow bars as necessary. Always take additional care to clean all the mating surfaces of the rotor and blow bar when flipping or replacing. This will assure that you maintain a metal-to-metal contact between the bars and the rotor.

Feed Opening

Maintain the rubber curtain and the chain curtain located in the feed opening of the crusher. These items are subject to wear and can be a safety hazard if damaged. Replace missing chain strands and missing rubber sections as necessary.

Pulley Guards

Keep tail pulley guards free of material build-up. Return any and all guards that have been removed prior to operating the unit.

Power Take-Off

Maintain proper adjustment of the power take-off, mounted to the back of the engine, if your unit is equipped with one. Consult the Operator’s Manual for proper adjustment procedures.


Inspect all conveyors daily for torn or punctured conveyor belts. Ensure that all troughing and return idlers are operating properly. Replace any idlers that are malfunctioning.
