Why Choose the Merit Front Head for Your HB 5800?

In a 6-ton class breaker like the Epiroc HB 5800, any material flaw in the front head leads to immediate and costly downtime. The Merit Front Head (Part No. 3363 0949 98) is engineered to prevent these failures through three key advantages:

1. Superior Forging Quality

Unlike cast housings, our forged front heads offer a much higher grain density. This eliminates the risk of internal porosities (air pockets) and provides significantly higher fatigue resistance under continuous, high-impact loads.

2. Precision Bushing Seats

The seating areas for both the upper and lower bushings are machined to micrometer tolerances. Perfect axial alignment ensures the working tool remains centered at all times. This prevents tool tilting and shields the HB 5800 strike pistonfrom dangerous lateral forces (side-loading).

3. Reinforced Wear Zones

We have specifically reinforced the critical areas surrounding the retainer pin bores. This reduces housing deformation caused by the extreme leverage forces encountered when prying or breaking massive rock formations.

Maintenance Protocols for the HB 5800

To maximize the service life of your 3363 0949 98 Front Head:

• Tolerance Checks: Regularly measure bushing clearance. Excessive play puts undue stress on the interior walls of the front head, leading to ovalization.
• Lubrication Management: Ensure your ContiLube™ II system is fully operational to minimize frictional heat buildup within the housing.
• Crack Detection: During scheduled maintenance, perform a thorough visual inspection for hairline fractures, particularly around the retainer pin seats and tie-rod bores.
