Genuine Furukawa T51 HD828 Drifter Shank Adapter Rod. This listing is for (1) one heavy-duty Furukawa Rock Drill (FRD) striking shank adapter rod configured for T51 thread series crawler drifter equipment. Engineered from high-tensile alloy carburized steel, this component interfaces between the hydraulic drifter piston and the drill string. It is precision-machined to absorb high-frequency impact energy while maintaining true axial alignment during demanding deep-hole blast production setups. Furukawa Rock Drill (FRD). HD828 / HD712 Series. T51 Male (Standard Rigidity Profile). 8-Spline Profile Drive Interface. Total Length (SAE / Metric). 25.39 in / 645 mm. Shaft Body Diameter (SAE / Metric). 2.05 in / 52 mm. Spline Section OD (SAE / Metric). 2.75 in / 70 mm. Central Through-Hole (Internal Water/Air Flush). MPN / Forging Numbers. ? Contractor & Mechanic Bench Measurement Guide. Pull your worn shank adapter and confirm these three precise data points with a caliper or tape measure. Total Length: Must measure approximately 25.39 inches (645 mm) from the flat striking rear face to the tip of the male threads. Spline Count & OD: Count exactly 8 drive splines on the backend chuck interface. The outside diameter across the highest point of the splines must measure 2.75 inches (70 mm). Thread Profile: The male drilling string thread must be a T51 large-profile rigid rock thread with an approximate outer thread diameter of 2.05 inches (52 mm). Rig Model Cross-Reference Note: Commonly utilized on top-hammer crawler drill rig setups including the Furukawa HCR1200 and HCR1500 series equipped with HD828 or compatible hydraulic drifters. Carburized Steel Composition & Mechanical Advantages. For the maintenance engineer and drilling superintendent, the metallurgy of a striking bar determines the exact cost-per-foot efficiency of the blast hole setup. This premium surplus shank adapter is manufactured from an advanced, low-carbon alloy steel base that has undergone a precision gas carburizing heat-treatment cycle, providing severe-duty performance enhancements. Dual-Zone Material Profile: The carburizing process diffuses carbon into the outer layer of the steel at extreme temperatures. This creates a high-hardness outer case (typically reaching 58-62 HRC) while retaining a ductile, resilient lower-carbon structural core. Extreme Fatigue Resistance: The high-hardness case places the surface under deep compressive residual stress. This structural barrier directly prevents the initiation and propagation of micro-fissures caused by the high-frequency tensile stress waves generated by the drifter piston. Anti-Galling Spline Geometry: Top-hammer rotation chucks generate severe sliding friction across the 8-spline drive end. The carburized surface chemistry lowers the coefficient of friction, preventing metal transfer, galling, and premature spline stripping under heavy rotational binding. Thread Flank Longevity: The T51 male thread flanks bear the combined force of rotation torque and reflective energy waves. A carburized structure ensures the thread profiles maintain their sharp factory geometry over extended drilling cycles, preventing cross-threading or premature loosening inside the coupling sleeve. Compatibility & Fitment Advisory. Equipment Type: Hydraulic Top Hammer Crawler Drill Rigs. Structural splines must align exactly without binding to avoid internal rotary head damage. Purchasing Perspective: For the fleet superintendent, operations manager, or field mechanic, carrying an uncompromised backup shank rod prevents catastrophic job site delays. High-tonnage drilling rigs lose profitability immediately when a shank shears down the hole; this industrial surplus item offers pristine OEM-spec alloy structure at a predictable price floor. Value-Add Inspection Notes: All 8 primary torque-transmission splines feature clear, well-defined profiles free of deformation. Striking surface is perfectly square and true to target. Condition Note: This is a new and unused item. The package was opened for inspection and photo purposes. The unit is guaranteed to be fully functional. You are purchasing the exact item shown in the photos. Item must be uninstalled, ungreased, and in original condition. Parts that show signs of piston impact, tool chuck engagement marks, or down-hole rotary wear are not eligible for return. Heavy Items: This component consists of solid high-density alloy steel. Years of industrial supply experience. Our Inventory & Sourcing. We specialize in genuine industrial and construction surplus. Our items are inspected for structural integrity and technical accuracy before listing. Heavy Equipment Components: If a striking bar or structural thread component shows signs of torque application, lubrication grease, or thread compound installation, it is no longer considered New. No warranties expressed or implied.
