Why Choose the Merit Caterpillar 160 Cylinder?
For heavy-duty breakers like the CAT 160, the cylinder is the single most critical component in determining hitting force. Merit cylinders are built to exceed original equipment standards with the following features:
1. Ultra-Smooth Internal Honing
The internal bore of the cylinder undergoes a precision honing process to achieve a mirror-like finish. This minimizes friction, allowing the piston to reach maximum velocity while significantly extending the life of your seal kits and preventing internal overheating.
2. High-Pressure Forged Construction
Manufactured from high-strength forged steel, the cylinder body is exceptionally resistant to hydraulic shocks and nitrogen pressure fluctuations. By eliminating micro-porosity in the metal, we’ve minimized the risk of fatigue cracking even under 24/7 operation.
3. Seamless “Bolt-On” Compatibility
Built according to the precise technical drawings for the 4TL00190 series, this cylinder is 100% compatible with your existing valve body, tie rods, and internal components. No modifications are required for installation, ensuring a fast return to service.
Key Benefits
- Maximum Impact Energy: Optimized bore dimensions ensure zero-loss power transfer to the tool.
- Thermal Stability: Special alloy composition controls expansion during long shifts in high-temperature environments.
- Extended Wear Life: Hardened internal walls resist corrosion and abrasive wear from hydraulic fluid contaminants.
Maintenance & Installation Advice
To maximize the lifespan of your new Caterpillar 160 cylinder:
- Replace Seals: Always install a brand-new, high-quality seal kit when replacing the cylinder.
- Fluid Hygiene: Ensure your hydraulic system is flushed and filled with fresh, clean oil before the first run.
- Nitrogen Calibration: To achieve full performance, calibrate the back-head gas pressure according to the CAT 160 factory specifications.
