Merit Premium Lower Bushing for Montabert (86582020) | Precision-Fit Heavy Duty Replacement

Why the Merit 86582020 Bushing is Your Best Choice

A Montabert hydraulic breaker is a high-performance machine that tolerates no compromises in part quality. Meritbushings provide the technical edge your equipment needs to stay on the job longer:

1. Superior Wear Resistance

We utilize a specialized deep-hardening process. This creates an ultra-hard surface designed to resist the abrasive nature of rock dust, while the core remains ductile and tough. This prevents the bushing from chipping or fracturing, even under extreme shock loads.

2. Optimized Precision Fit

Thanks to state-of-the-art CNC manufacturing, we guarantee minimal tolerances. A perfectly seated bushing eliminates "tool flutter," protecting the piston’s strike face and significantly reducing wear on your hammer’s internal seals.

3. Excellent Lubrication Properties

The internal geometry of the Merit 86582020 bushing is engineered for uniform distribution of chisel paste. This prevents dry-running, reduces frictional heat, and substantially extends the service life of both the bushing and the working tool.

Maintenance Alert: When Should You Replace the Bushing?

Proactive replacement of the 86582020 bushing is the most cost-effective way to shield your hammer from expensive secondary damage:

• Wear Inspection: Regularly measure the clearance between the tool and the bushing. Once the maximum wear limit is exceeded, "angular strikes" occur, which place massive stress on the internal mechanism.
• Piston Protection: A worn bushing causes the piston to hit the tool off-center. This misalignment can lead to catastrophic damage to both the piston and the cylinder bore. Replace the bushing early to save the hammer.
