Maximize the efficiency and lifespan of your heavy-duty demolition equipment with the premium Upper Chuck Bushing (Upper Tool Guide), engineered explicitly for high-performance Montabert hydraulic rock breakers. Operating in the demanding environments of the Middle East and Gulf Cooperation Council (GCC) regions—ranging from high-temperature quarry sites in Riyadh and Jeddah to major infrastructure developments in Dubai, Doha, and Muscat—demands robust, precision-engineered replacement parts capable of handling intense cyclical stress and extreme heat without structural distortion.
Since 2005, Merit has been a leading global manufacturer and independent supplier of OEM-equivalent hydraulic breaker parts from Turkey. This upper chuck bushing is designed to serve as a direct-fit aftermarket equivalent to the original factory component with part number 86719143 (cross-referenced as Montabert 86719143 Bushing). Produced from premium-grade alloy steel and treated with advanced metallurgical carburization, this component effectively secures correct chisel alignment, dampens destructive side-thrust forces, and shields the expensive hammer piston from micro-cracks, rapid scoring, and premature breakdown.
Key Performance Features & Engineering Advantages:
- Perfect Dimensional Tolerances: Precision-ground using advanced CNC machinery to meet exact technical clearances, ensuring a swift and secure press-fit installation within the front head of your Montabert breaker.
- Optimized Internal Lubrication: The inner diameter features integrated lubrication grooves that ensure the steady retention and equal distribution of high-temperature chisel paste, eliminating dry metal-to-metal friction.
- Sacrificial Component Protection: Engineered with precise hardness ratios to absorb severe lateral friction during blank firing, thereby preventing costly wear on the hammer housing and complementary heavy rock breaker components.
- Thermal Shock Resistance: Built to thrive in harsh desert operations, our alloy retains its core toughness and resists surface fatigue even during continuous, high-frequency operation in high ambient temperatures.
Machinery and Excavator Compatibility: This heavy-duty upper tool guide delivers strict stability for Montabert breakers mounted on standard and heavy crawler excavators from major global brands across Middle Eastern project sites:
- Caterpillar (CAT): Structural utility and mining-grade excavators (CAT 330, CAT 336, CAT 345, CAT 349 Series).
- Komatsu: Heavy-duty earthmoving and track machinery (PC300, PC360, PC400, PC450 Series).
- Volvo / Hitachi / Doosan: High-capacity infrastructural tracked excavators (EC380, EC480, ZX330, ZX350, DX340 Series).
Global Logistics, Procurement & Direct Delivery to GCC & Worldwide:
- Minimized Operational Downtime: Fast, dependable air-freight and sea-freight shipping options dispatched directly from our manufacturing facility in Turkey straight to major logistics hubs and industrial ports, including Jebel Ali (Dubai), King Abdulaziz Port (Dammam), and Doha.
- Full Export Clearance Compliance: Merit supplies all necessary international trade documentation, certificates of origin, and explicit commercial invoices to support rapid, hassle-free customs handling.
