Restore the hydraulic integrity and striking power of your equipment with the Merit High-Performance Seal Kit, specifically engineered for the Rammer 5011E. In heavy-duty breaking applications, the sealing system is the most critical factor in preventing pressure loss, oil leaks, and internal contamination. This kit is built to withstand the extreme pressure spikes and high thermal loads typical of the 5-ton Rammer series.

Why Choose the Merit Rammer 5011E Seal Kit?
The Rammer 5011E is a powerhouse that generates massive impact energy. To keep this power consistent, the internal seals must remain tight under high frequency. The Merit kit offers:
1. Dynamic Pressure Resistance
The piston in a 5011E moves at high speeds with intense pressure cycles. Our Step Seals and Buffer Seals are manufactured from reinforced polyurethane that resists deformation and extrusion, ensuring the piston maintains maximum velocity without internal oil bypass.
2. Advanced Heat Management
Continuous operation in hard rock lead to high hydraulic fluid temperatures. Merit seals are made from heat-stabilized compounds that won’t harden or crack under thermal stress, preventing the “sudden leak” syndrome common with low-quality aftermarket kits.
3. Protection Against Contamination
Operating in dusty, abrasive environments requires superior protection. This kit includes heavy-duty Dust Wipersdesigned to scrape the piston clean on every stroke, preventing fine stone particles from entering the hydraulic circuit and scoring the cylinder walls.
Complete Repair Solution
The Merit kit is a comprehensive 100% solution for a professional rebuild, containing:
- Main Piston Seals: For high-impact power cycles.
- Gas Seals: To maintain nitrogen pressure in the back head.
- Buffer Seals: To absorb hydraulic shock and protect the main seal stack.
- Wiper Seals: To protect the internal system from external debris.
- O-Rings & Back-up Rings: For the valve body and housing ports.
Maintenance Tip: When to Reseal?
To prevent damage to the expensive cylinder and piston, reseal your Rammer 5011E every 600 to 800 operating hours, or immediately if you notice:
- Oil Leaking: Visible oil dripping from the tool (chisel) area.
- Recoil Vibration: Excessive vibration in the excavator boom.
- Power Loss: The hammer strikes with less force or sounds “muffled.”
Pro Installation Note: Ensure absolute cleanliness during installation. A single grain of sand can ruin a new seal. Always lubricate the seals with clean hydraulic oil before assembly.
