Expert Tips from KastRock


As an authorized Eagle Iron Works dealer, we at KastRock have seen firsthand how proper maintenance can extend the life of aggregate washing equipment. 

Essential Oil Maintenance for Your Coarse Material Washer

The heart of your washer's performance lies in proper oil maintenance. When checking oil levels, ensure your machine is in operating position but not running. The ideal oil level should align with the pipe plug opening on the gear case's front.

For optimal performance, Eagle Iron Works recommends:
• Annual oil changes or replacement after 2,000 operating hours
• Using climate-appropriate oil viscosity
• Maintaining consistent oil brand usage to prevent compatibility issues

Oil Capacity Guidelines by Machine Size:
• 20" and 24" models: 3 gallons
• 30" and 36" models: 14 gallons
• 44" and 48" models: 19 gallons
• 54" models: 34 gallons
• 66" and 72" models: 70 gallons

Critical Components Monitoring

Bearing and Motor Health
Your daily inspection routine should include monitoring bearings and motors for unusual heat or noise. Our service team emphasizes the importance of:
• Checking bearing temperature each shift
• Keeping motor fins clear of material buildup
• Removing debris that could affect cooling

Tub and Drive System Maintenance
Regular inspection of the washer tub prevents operational issues. Pay special attention to:
• Clearing debris that might interfere with shaft rotation
• Checking V-belt alignment and tension weekly
• Protecting the spider and flange assembly from sand infiltration

Preventive Maintenance Schedule

Eagle Iron Works recommends implementing a tiered maintenance schedule:

Daily Tasks
• Monitor bearing and motor temperatures
• Clear debris from the washer tub
• Verify all guards are properly secured

Weekly Tasks
• Inspect V-belt condition and alignment
• Check rubber cover integrity on drive components
• Clear excess grease from bearing vent openings

Monthly Tasks
• Evaluate wear shoes and paddles (or every 250 operating hours)
• Inspect all fasteners and mounting hardware
• Document wear patterns for future reference

Essential Spare Parts Inventory

To minimize downtime, you should maintain an inventory of these critical components:
• Replacement bearings
• V-belt sets
• Wear shoes
• Paddle assemblies
