Why Choose the Merit 3361 0315 46 Threaded Insert?
Hydraulic breakers are subjected to thousands of high-frequency blows per minute. This constant energy can cause standard threads in cast housings to fatigue, stretch, or strip. The Merit 3361 0315 46 insert is the professional solution to these challenges:
1. Engineered for High Vibration
Standard threading often fails under the harmonic resonance of a hydraulic hammer. The Merit insert is designed with precise thread geometry that distributes load evenly, preventing “bolt creep” and ensuring that your side plates and mounting brackets stay tight.
2. Cost-Effective Housing Repair
If the internal threads of an expensive front head or cylinder body become damaged, replacing the entire component is financially draining. Installing the 3361 0315 46 insert allows you to restore the thread to OEM strength, extending the life of the main breaker body.
3. Premium Material Strength
Manufactured from hardened alloy steel, our inserts are significantly tougher than the base metal of the breaker housing. This provides a wear-resistant interface that can handle repeated disassembly and re-assembly during routine maintenance without stripping.
Key Benefits
- OEM Specification Match: Fully compatible with Atlas Copco and Epiroc part number 3361 0315 46.
- Increased Pull-out Strength: Provides a deeper, more secure grip for assembly bolts.
- Corrosion Resistant: Treated to prevent seizing, ensuring easier bolt removal during future servicing.
Maintenance Tip: When to Replace Inserts?
During every 500-hour service or major overhaul, inspect the 3361 0315 46 inserts for:
- Thread Flattening: Shiny or smoothed-out thread peaks inside the insert.
- Cracks: Any visible hairline fractures in the insert wall.
- Looseness: If the insert itself shows movement within the housing, it must be replaced immediately to prevent housing damage.
Installation Note: Always use the recommended thread-locking compound and specialized installation tools to ensure the insert is seated at the correct depth and torque.
