Merit Front Head for Rammer E68 (Part No. 110713) | Maximum Structural Stability

Why the Merit 110713 Front Head is the Superior Choice

The front head is constantly exposed to violent vibrations and abrasive dust. A failure in this component can lead to a total hammer breakdown. Merit relies on superior engineering to mitigate these risks:

1. High-Performance Forged Construction

Unlike cast alternatives that often contain porosities (air pockets), the Merit 110713 Front Head is manufactured from forged steel. This process aligns the metal’s grain structure for maximum resistance against the massive shock loads generated by a 4-ton hammer.

2. Perfect Concentricity of Bushing Seats

The internal bores of our front heads are machined on high-precision CNC centers. This ensures that the upper and lower bushings are perfectly concentric. Correct alignment prevents tool tilting and protects your 100660 Piston from expensive damage caused by lateral forces (side-loading).

3. Reinforced Retainer Pin Zones

One of the most common weak points in a front head is the area surrounding the retainer pins. Merit has reinforced the geometry around the pin bores in the 110713 design to prevent deformation and cracking, even when using long chisels in hard rock formations.

Maintenance Tips for Maximum Service Life

The 110713 Front Head is a rugged component, but proper care is essential:

• Pin Inspection: Regularly check the tool retainer pins. Worn or mushroomed pins can deform the bores within the front head, making tool changes difficult and weakening the structure.
• Bushing Replacement: Never allow bushings to operate beyond their wear limits. Excessive tool play exerts enormous leverage on the interior walls of the front head, leading to structural fatigue.
• Welding Prohibited: Never perform unauthorized welding on the front head. The specialized heat treatment of the 110713 can be compromised by extreme heat, leading to brittle fractures during operation.
