Designed for high-performance compact utility equipment, this multi-part component group encompassing OEM numbers 51630297, 84379154, and 47504389 represents a critical assembly group tailored for radial-lift and vertical-lift skid steer loaders (SSL) and compact track loaders (CTL) across the Case and New Holland brand families.
Modern compact loaders endure intense operational cycles characterized by heavy breakout forces, high hydraulic pressures, continuous ground vibrations, and rapid directional shifts. These multi-application components are engineered from premium-grade alloys and heavy-duty composite polymers to deliver uncompromising structural integrity, pressure containment, and wear resistance.
Universal Cross-Platform Fitment: Engineered to bridge multiple generations of C-Series and B-Series Case and New Holland machinery, minimizing inventory friction for fleet managers.
Extreme Duty Tolerance: Optimized for high-vibration and high-torque environments, preventing micro-fractures and premature fatigue failure.
Corrosion and Thermal Defense: Surface-passivated and treated with advanced protective barriers to withstand exposure to mud, corrosive fertilizers, hydraulic oils, and extreme weather fluctuations.
To ensure seamless inventory intake and shop-floor accuracy, the reference package comprises the following engineered elements:
Primary Structural / Hydraulic Sub-Assembly (Part Nos. 51630297 / 84379154 / 47504389 Collective Group):
Material Specification: Forged high-tensile carbon steel / Specialized elastomeric matrix.
Function: Acts as the primary stress-bearing or fluid-routing interface, maintaining structural rigidity and pressure stability under maximum payload conditions.
Precision Sealing & O-Ring Interface Kit:
Material Specification: High-saturation Nitrile and Viton fluorocarbon elastomers.
Fastener & Hardware Anchorage Set:
Material Specification: Grade 10.9 yellow zinc-chromate coated steel hardware.
Function: Secures assemblies against vibrational loosening during heavy grading, trenching, and lifting operations.
This component group is custom-engineered to match factory blueprint dimensions, hydraulic routing paths, and mounting bolsters for an extensive array of Case and New Holland compact track and skid steer loaders.
Radial-Lift Skid Steers: SR220, SR240, SR240B, SR250
Vertical-Lift Skid Steers: SV250, SV280, SV280B, SV300
Compact Track Loaders (CTL): TR320, TV370, TV370B, TV380
Compact Track Loaders: C232, C237, C238, C332, C337
Radial / Vertical Skid Steer Loaders: L223, L225, L228, L230, L328
Note: Due to mid-production serial number updates by CNH Industrial, always verify your equipment's unique product identification number (PIN) against your factory parts manual before installation.
Executing a safe and compliant installation protects your machinery from secondary damage and ensures operator safety. Always adhere to the following steps:
Machine Isolation & Secure Parking: Park the loader on a flat, solid concrete surface. Lower the loader arms completely to the ground or engage mechanical lift-arm safety braces. Apply the parking brake and shut down the diesel engine.
System De-Pressurization: If servicing hydraulic or pressurized fluid interfaces, cycle the joystick controls with the engine turned off to bleed all residual pressure from the accumulators and lines.
Clean Workspace Environment: Use industrial degreaser and compressed air to clean around the installation zone. Ingress of dirt or grit into hydraulic ports or precision housings will cause immediate component failure.
Torque Specifications: Install new seals (lightly lubricated with clean hydraulic oil) and hand-thread all fasteners. Using a calibrated torque wrench, tighten bolts in a cross-pattern sequence according to standard CNH factory torque charts. Never overtighten.
Functional Leak & Pressure Check: Refill fluids to proper dipstick levels. Start the engine at low idle, slowly actuate machine functions, and inspect meticulously for fluid weeping, unusual noise, or binding.
A: Yes. Because Case IH and New Holland operate under CNH Industrial, many platform components—including chassis brackets and hydraulic/structural sub-assemblies—share identical engineering specifications across corresponding models like the Case TV370 and New Holland C337.
A: These are premium aftermarket replacement elements engineered to meet or exceed OEM dimensional tolerances and metallurgical thresholds, offering professional-grade reliability at a competitive maintenance cost.
A: We recommend a visual walk-around inspection daily for signs of seepage or loose hardware, with a comprehensive torque check performed after the first 50 operating hours following installation.
