Prevent leaks and maintain peak power in your Rammer 5011 breaker with the 170948 Seal Set. Essential for MERIT in Reliability and Efficiency. Shop quality.
The Seal Set (or Service Kit, Part Number 170948) for the Rammer 5011 hydraulic breaker is a collection of various elastomeric and PTFE seals, O-rings, and specialized rings required to replace all dynamic and static seals within the power cell. These seals are the critical barrier that maintains hydraulic pressure integrity and prevents contamination between internal components. Since seals operate under extreme pressure, high temperatures, and continuous friction, they are regular replacement items.
The acronym MERIT (Maintenance, Endurance, Reliability, Integrity, Tool Life) directly defines the value of a quality seal kit:
Maintenance: The seal set is the heart of routine Maintenance. Replacing seals at the recommended interval prevents fluid leaks and costly internal damage caused by pressure loss or contamination, ensuring proactive equipment care.
Endurance: High-quality seals are manufactured from specific compounds (like NBR or FKM) chosen for their exceptional Endurance against abrasive hydraulic fluid, heat, and the intense mechanical cycling within the breaker. Inferior seals quickly fail, leading to downtime.
Reliability: The seals ensure the Piston’s chambers achieve and hold the necessary pressure for the percussion cycle. Intact seals guarantee the consistent Reliability and full force of the impact blow, preventing the hammer from “gassing out” or failing to cycle.
Integrity: Seals maintain the hydraulic Integrity of the system. They separate high-pressure areas from low-pressure areas and protect the precision-machined surfaces of the Piston and Cylinder from scoring. Leaking seals compromise the entire circuit, causing overheating and loss of power.
Tool Life: While not directly striking the tool, effective seals are vital for maintaining the hammer’s designed stroke and impact energy. By ensuring maximum hydraulic power is delivered, the seal kit indirectly supports high performance and maximized Tool Life.
A genuine or high-quality OEM-equivalent Rammer 5011 Seal Set (170948) is the most cost-effective way to restore the full operational MERIT and power efficiency of your hydraulic breaker.
Replace your Rammer 5011 Lower Tool Bushing (PN 178418) for optimal tool guidance. Critical component for MERIT, reducing tool play and internal wear.
The Lower Tool Bushing (Part Number 178418 for the Rammer 5011, sometimes listed as 171139) is a high-wear component located in the front head of the hydraulic breaker. Its primary function is to guide and stabilize the working tool (chisel, moil point) and absorb the massive radial forces that occur when the tool breaks rock and concrete. It is essential for minimizing tool sway and ensuring the percussion piston strikes the tool cleanly.
The acronym MERIT (Maintenance, Endurance, Reliability, Integrity, Tool Life) is directly applicable to the bushing’s role:
Maintenance: A worn bushing allows excessive tool movement, leading to mushrooming of the tool shank and increased stress on the internal piston and seals. Timely replacement is inexpensive preventive Maintenance that protects high-cost internal parts.
Endurance: The bushing is designed to be the sacrificial wear item, absorbing abrasive friction and side loads. High-quality bushings are made from special alloys with optimal lubrication channels to maximize Endurance against wear and galling.
Reliability: The proper fit between the tool and the bushing is crucial for consistent energy transfer. A worn bushing causes sloppy tool movement, reducing the Reliability and effectiveness of each blow. Replacing it restores the precise fit required for peak performance.
Integrity: The bushing maintains the geometric Integrity of the tool’s path. When the internal diameter wears beyond tolerance, the tool tilts, creating uneven wear on the upper tool bushing and increasing the risk of scoring the front face of the piston.
Tool Life: By providing precise guidance and proper support, the lower bushing ensures the tool is held straight during the breaking cycle. This minimizes non-axial stresses on the tool shank, directly extending the Tool Life of the expensive chisel or moil point.
The Rammer 5011 Lower Tool Bushing (178418) is a relatively small part with a massive impact on the MERIT and operational efficiency of the entire hydraulic breaker.
Secure your Rammer 5011 breaker’s power cell with a Complete Tie Rod Kit (PN 168595). Essential for MERIT in Endurance and Structural Reliability.
The Complete Tie Rod Assembly (Part Number typically 168595) in the Rammer 5011 hydraulic breaker is the backbone of the entire structure. These large, high-tensile bolts (usually four) run the entire length of the breaker’s power cell, externally clamping the cylinder, accumulator, and other main components together. The tie rods are constantly under massive static pre-load tension and cyclical dynamic stress, making them critical for the breaker’s safety and performance.
Applying the acronym MERIT (Maintenance, Endurance, Reliability, Integrity, Tool Life) to the Complete Tie Rod:
Maintenance: A healthy tie rod assembly reduces component wear by maintaining the correct clamping force. This prevents excessive movement and friction between the housing and the inner components, reducing the need for minor Maintenance and preserving the seal sets.
Endurance: Tie rods must exhibit exceptional Endurance against fatigue failure. They are made from specialized, high-alloy steel (often employing VIDAT technology in Rammer models) to resist the constant tension, compression, and vibration that occur during thousands of blows per hour.
Reliability: The tie rods ensure the axial alignment of all internal components, including the cylinder and piston. Maintaining this precise alignment is fundamental to the Reliability of the percussion mechanism and prevents costly secondary damage caused by misalignment.
Integrity: Tie rods provide the structural Integrity for the entire breaker. If a rod fails, the clamping force is lost, often leading to a catastrophic separation of the breaker components, which is both dangerous and extremely expensive. Using a complete, high-quality kit ensures uniform stress distribution.
Tool Life: By holding the breaker body together rigidly, the tie rods ensure that maximum energy is transferred efficiently to the tool. They prevent energy dissipation through unnecessary flexing of the housing, indirectly contributing to consistent performance and maximized Tool Life.
A high-grade Rammer 5011 Complete Tie Rod is therefore not just a fastener; it is a specialized component that secures the structural and hydraulic MERIT of the breaker.
Maintain the precision of your Rammer 5011 breaker with a high-integrity Cylinder replacement. Essential for maximizing impact MERIT and internal longevity.
The Cylinder is the primary housing and functional body of the Rammer 5011 hydraulic breaker. It is the chamber within which the Piston (Striker) reciprocates, acting as the foundation for the entire percussion mechanism. The hydraulic cylinder contains precision ports and galleries that control the flow of oil, timing the blows and generating the force necessary for breaking. Its internal surface, or bore, is critical, as any imperfection can lead to massive power loss.
Applying the acronym MERIT (Maintenance, Endurance, Reliability, Integrity, Tool Life) to the Cylinder:
Maintenance: A cylinder manufactured with precise bore tolerances and surface finish is crucial for minimizing wear on the seals and the Piston itself. This precision reduces the need for frequent internal Maintenance and costly repairs.
Endurance: The cylinder is subjected to enormous hydraulic pressure fluctuations and mechanical stress from the Piston’s movements. A quality replacement is forged from robust, high-tensile steel, ensuring maximum Endurance against expansion, fatigue, and potential cracking.
Reliability: The internal ports must be perfectly aligned and sized to ensure the oil correctly directs the Piston—a process known as valve timing. This perfect hydraulic choreography provides consistent and powerful blows, guaranteeing the Reliability of the breaker’s performance under heavy load.
Integrity: The Integrity of the cylinder bore’s smooth, hardened surface is paramount. Any scoring or scratching compromises the seal, leading to internal leakage (bypass), which results in a significant drop in impact energy and high oil temperatures.
Tool Life: A cylinder with proper dimensional integrity ensures the Piston travels along a true path. This precision prevents misalignment of the Piston strike on the tool, indirectly extending Tool Life by reducing side loading and uneven wear on the chisel.
In essence, investing in a high-quality Rammer 5011 Cylinder is fundamental to upholding the MERIT of the entire breaker, ensuring efficient, powerful, and long-lasting operation.
Restore peak impact power to your Rammer 5011E breaker with a precision-engineered Piston (PN 168564). Unrivaled MERIT in Material, Reliability & Durability.
The Piston (or Striker) in the Rammer 5011 E hydraulic breaker is the core moving component. It is a high-precision, high-stress part that accelerates and decelerates thousands of times per hour, converting hydraulic pressure into kinetic energy to strike the breaking tool. Its quality is the single most critical factor determining the breaker’s power output and overall service life.
Applying the acronym MERIT (Maintenance, Endurance, Reliability, Integrity, Tool Life) to the Piston:
Maintenance: A high-quality piston minimizes friction and wear on cylinder walls and seals, thereby reducing heat generation and extending the service interval for seal kits and internal Maintenance.
Endurance: The Piston must withstand immense thermal and mechanical shock. Premium pistons are crafted from high-grade alloy steel and undergo specialized, precise heat treatment to ensure superior Endurance against cracking, chipping, and surface fatigue under continuous operation.
Reliability: Precision engineering ensures the Piston maintains exact clearances within the cylinder. This tight tolerance is vital for the Reliability of the valve timing and the consistent transfer of hydraulic energy into a powerful, controlled blow.
Integrity: The surface finish and dimensional Integrity of the Piston are paramount. Flaws can lead to rapid seal wear and scoring of the cylinder bore, resulting in a catastrophic loss of impact energy and pressure. A flawless piston maintains the hydraulic circuit’s integrity.
Tool Life: As the component that directly strikes the breaking tool, its weight, velocity, and alignment are perfectly balanced to deliver maximum energy. A well-functioning Piston ensures the tool is struck squarely and consistently, maximizing Tool Life and overall breaking efficiency.
A Rammer 5011E Piston built to the highest specifications (PN 168564) is an essential investment that guarantees maximum impact energy and prolonged operational MERIT for your heavy-duty applications.
