Purchasing a used hydraulic breaker can offer significant cost savings, but it also presents unique maintenance challenges. We understand that maximizing equipment lifespan and minimizing downtime are crucial for your operations. Our team, with over 15 years of experience in hydraulic breaker design, application, and maintenance, provides a comprehensive guide to the critical maintenance aspects you must consider before and after acquiring a pre-owned unit. This detailed approach ensures that your investment remains productive and reliable.
Key Maintenance Concerns Before Purchase
Before finalizing the purchase of a used hydraulic breaker, a thorough inspection and evaluation of its maintenance history are essential. Neglecting these steps can lead to unforeseen repair costs and operational disruptions. We focus on identifying potential issues early to safeguard your investment.
Comprehensive Visual Inspection
A detailed visual inspection reveals much about a breaker’s past usage and potential wear. We meticulously examine the external and internal components for any signs of damage or excessive wear.
External Casing and Mountings
Check the breaker box for cracks, severe dents, or signs of improper welding. The integrity of the outer casing is vital for protecting internal components. We also inspect the mounting bracket for distortion or wear, ensuring it aligns correctly with your carrier. Any significant damage here indicates harsh operating conditions or poor maintenance.
Working Tool and Tool Pins
Examine the working tool for excessive wear, bending, or mushrooming. A heavily worn tool suggests prolonged use without proper lubrication or incorrect application. Inspect the tool pin and bushing pin for wear, which can indicate play between the tool and the front head. Excessive play accelerates wear on critical internal components.
Hydraulic Hoses and Connections
Look for leaks, cracks, or abrasions on the hydraulic hoses. Ensure all hydraulic connections are secure and free from corrosion. Damaged hoses or loose connections can lead to oil leaks, pressure loss, and potential safety hazards.
Internal Component Assessment
While a full disassembly is often impractical before purchase, certain indicators can reveal the condition of internal components. We prioritize checks that provide insights into the breaker’s operational health.
Accumulator Condition
The accumulator is a critical component for impact performance and system protection. Check for signs of leakage around the accumulator or a noticeable drop in performance during a test run. A faulty accumulator can lead to reduced breaking power and increased stress on the hydraulic system.

Seal Integrity
Although not always visible, signs of oil leakage around the piston or front head indicate worn seals. A complete seal kit replacement is a common maintenance task for used breakers. We recommend budgeting for this, as seal failures can lead to significant hydraulic fluid loss and system contamination.
Piston and Cylinder Wear
Listen for unusual noises during operation, such as knocking or grinding. These sounds can indicate wear on the piston or cylinder body assembly. Requesting maintenance records can provide valuable information on past repairs or replacements of these core components.
Evaluating Maintenance History and Documentation
The maintenance history of a used hydraulic breaker offers a clear picture of its past care and potential future needs. We emphasize the importance of comprehensive documentation.
Reviewing Service Records
Request detailed service records from the seller. These records should include routine maintenance, repairs, and part replacements. Look for consistent greasing schedules, oil changes, and accumulator recharges. A lack of records often signals neglected maintenance.
Identifying Common Wear Parts Replacements
Pay attention to the frequency of wear part replacements, such as bushings, tool pins, and seals. Frequent replacements might indicate severe operating conditions or improper usage. Conversely, a history of timely replacements suggests good maintenance practices.

Previous Owner’s Operating Practices
Inquire about the previous owner’s typical applications and operating environment. Breakers used in highly abrasive materials or extreme conditions tend to experience faster wear. Understanding the operational context helps predict future maintenance requirements.
Post-Purchase Maintenance Strategies
Once you acquire a used hydraulic breaker, implementing a robust maintenance strategy is paramount. We advocate for proactive measures to extend the breaker’s lifespan and ensure optimal performance.
Initial Service and Inspection
Upon purchase, conduct a comprehensive service. This includes replacing all hydraulic fluids and filters, checking and recharging the accumulator, and replacing the seal kit. This initial overhaul establishes a baseline for future maintenance.
Hydraulic System Flush
Flush the hydraulic system of your carrier to remove any contaminants from the previous attachment. This prevents cross-contamination and protects your new-to-you breaker.
Accumulator Pre-charge Check
Verify the accumulator gas pressure using a charging regulator. The correct pre-charge pressure is crucial for efficient operation and to prevent damage to the breaker and carrier.
Regular Lubrication and Greasing
Proper lubrication is the single most important factor in extending the life of a hydraulic breaker. We recommend using high-quality chisel paste and adhering to a strict greasing schedule.
Daily Greasing Protocol
Grease the working tool and bushings daily, or even multiple times a day depending on the application. This minimizes friction and wear between the tool and the front head. Consider installing an automatic lubrication system for consistent and hassle-free greasing.
Chisel Paste Selection
Use a specialized chisel paste designed for high-temperature and high-pressure applications. Standard grease may not provide adequate protection under the extreme conditions experienced by a hydraulic breaker.
Routine Checks and Inspections
Implement a routine inspection schedule to catch minor issues before they escalate into major problems. Regular checks save time and money in the long run.
Fastener Torque Checks
Periodically check the torque of all bolts, especially the shell bolts and linkage bolts. Loose fasteners can lead to excessive vibration, component wear, and structural damage.
Tool and Bushing Wear Monitoring
Regularly inspect the working tool and bushings for wear. Replace them proactively when they reach their wear limits to prevent damage to more expensive internal components.

Expert Insight
Our experience shows that the most significant factor impacting the lifespan of a used hydraulic breaker is consistent and correct lubrication. Many operators underestimate the importance of proper greasing, leading to premature wear of the working tool and bushings. For example, our data indicates that breakers with an automatic lubrication system experience up to a 30% reduction in tool wear compared to those relying solely on manual greasing. This highlights the substantial benefit of investing in automated lubrication solutions and adhering to recommended greasing intervals.
