Why Choose the Merit K12577E Service Kit?
Rammer breakers are known for their reliability, but their internal seals are subject to extreme heat and high-frequency friction. The Merit K12577E kit is engineered to withstand these conditions:
1. Advanced Piston Sealing
Our main dynamic seals are made from 95 Shore A Polyurethane, which offers superior wear resistance and elastic memory. This ensures that even under high operating temperatures, the seals maintain a perfect contact surface with the piston, preventing internal oil bypass and “lazy” hitting.
2. Maximum Gas Retention
A breaker’s power depends on its nitrogen charge. The K12577E kit includes specialized static and dynamic gas seals designed to be impermeable to nitrogen. This reduces the need for frequent gas refills and protects the hammer from losing striking force during long shifts.
3. Complete Component Protection
In addition to the main seals, our kit includes high-tensile Dust Wipers. These are critical for demolition environments, as they scrape abrasive particles off the piston before they can enter the cylinder and cause expensive scoring or scratches.
What is Included in the K12577E Kit?
This is a comprehensive service solution that typically includes:
- Piston Seals: High-pressure dynamic seals.
- Buffer Seals: To dampen pressure spikes.
- Wiper Seals: To protect against external contamination.
- O-Rings & Back-up Rings: For the valve body, side bolts, and accumulator.
- Gas Valve Seals: To ensure the nitrogen chamber is airtight.
Maintenance Tip: When to use the K12577E Kit?
- Every 600 Hours: Routine preventative maintenance significantly lowers the total cost of ownership.
- Visible Oil Leaks: If oil is appearing on the tool shank or leaking from the housing.
- Loss of Frequency: If the hammer is striking slower than normal, it usually indicates internal seal wear.
- Discolored Oil: If your hydraulic oil appears foamy, nitrogen may be leaking past the gas seals into the oil circuit.
