At the core of every reliable heavy-duty truck lies a robust steering axle system, and its most critical pivot point is the kingpin. As a fundamental component in the lineup of durable SANY parts, the OEM 60335146 Kingpin assembly is engineered to restore the integrity and responsiveness of your truck’s front steering.
This genuine part, identified by the precise reference number 60335146, is manufactured to exacting SANY specifications to ensure a perfect fit, superior wear resistance, and reliable performance under extreme loads. Replacing worn kingpins with the authentic 60335146 assembly eliminates steering play, reduces tire wear, and is essential for maintaining safe vehicle handling. For fleet managers and owners of SANY trucks, this component is a direct investment in safety, control, and reduced long-term maintenance costs.

The kingpin is the central pivot bolt in the steering knuckle assembly of a solid front truck axle. It allows the wheel and knuckle to turn left and right while supporting the vehicle’s weight. The SANY 60335146 Kingpin is not a simple bolt; it is a precision-ground, hardened steel component designed to withstand immense shear forces and continuous rotational stress. Over time, the original kingpin and its corresponding bushings can wear down, leading to dangerous steering looseness, uneven tire wear, and compromised vehicle stability.
Replacing these worn components with the genuine 60335146 assembly restores the tight, factory-specified clearance between the kingpin and the knuckle. This is crucial because excessive play translates directly to imprecise steering input, causing the driver to make constant small corrections. The high-quality materials and precise tolerances of the 60335146 part ensure longevity and reliable performance, making it a fundamental repair for any SANY truck experiencing steering wander or front-end looseness. Using the correct 60335146 part guarantees the steering geometry remains as designed by SANY engineers.
The core of the 60335146 kingpin is forged from high-grade alloy steel. It undergoes a precise induction hardening process, creating an incredibly hard, wear-resistant outer surface while maintaining a tough, shock-absorbing core to prevent brittle fracture.
The bearing surfaces of the 60335146 are ground to microscopic tolerances. This mirror-smooth finish minimizes friction against the bushings, promotes proper lubrication retention, and ensures consistent, smooth steering action without binding.
Designed with strategically machined grooves and Zerk fitting threads, the 60335146 allows for positive-pressure greasing. This forces fresh lubricant into the critical interface between the pin and bushing, flushing out contaminants and preventing dry wear.
A protective phosphate or similar coating is applied to the 60335146 to inhibit rust and corrosion during storage and in-service. This extends the component’s life, especially in regions with road salt or high humidity.
Often supplied as part of a kit, the 60335146 kingpin comes with all necessary complementary parts: high-quality bronze or polymer bushings, thrust washers, seals, and locking pins for a comprehensive front-end repair solution.
As a genuine SANY part, the 60335146 has the exact dimensions, thread pitch, and hardness specifications of the original component it replaces. This guarantees correct fitment, proper load distribution, and restored factory performance.

Ignoring kingpin wear can lead to dangerous driving dynamics and costly secondary damage. Recognize these common signs that indicate the need for replacement with the genuine 60335146 assembly:
The SANY 60335146 kingpin kit addresses all these issues by providing a complete, high-precision replacement system. Installing it restores the critical clearances, ensures proper lubrication, and re-establishes a solid, predictable pivot point for the steering knuckle.
Kingpin replacement (part number 60335146) is a complex, heavy-duty repair that requires specialized tools (kingpin press, reamers, torque wrenches) and expertise. The process typically involves: 1) Jacking and securing the truck, removing the wheel and brake assembly. 2) Removing the old, worn kingpin using a hydraulic press. 3) Thoroughly cleaning and inspecting the steering knuckle and axle eye.
4) Pressing in new, high-quality bushings and reaming them to the exact size for the new 60335146 kingpin. 5) Installing the new pin with appropriate thrust washers and seals. 6) Torquing the lock nut to precise specification and installing the locking pin. 7) Reassembling components and performing a front-end alignment. Due to the safety-critical nature of this component, professional installation is strongly advised.
Proper maintenance is key to extending the life of your new 60335146 kingpin. After installation, lubricate the fittings with a high-pressure, lithium-based chassis grease until clean grease purges from the seals. Establish a regular greasing schedule as per the vehicle’s service manual (often every oil change or 10,000-15,000 miles). During routine maintenance, visually check for any signs of seal damage or grease leakage. Listen for new noises and monitor tire wear patterns.
A properly installed and maintained 60335146 kingpin assembly should provide reliable service for hundreds of thousands of kilometers. Always use the correct grease and a clean grease gun to avoid injecting contaminants into the new joint.
Choosing a non-genuine or substandard kingpin can lead to significant safety risks and higher long-term costs. The genuine SANY 60335146 part offers unmatched value.
Genuine 60335146 uses certified alloy steel with verified hardness. Inferior parts may use softer metals that deform under load, causing rapid wear and failure.
OEM parts like 60335146 are machined to micron-level tolerances for a perfect fit. Incorrect dimensions can cause binding, improper loading, and accelerated bushing wear.
This component is safety-critical. The genuine 60335146 has been tested and validated by SANY for your specific axle model, ensuring it can handle the designed stresses.
The 60335146 comes with SANY’s genuine parts warranty. This coverage is void if non-OEM parts fail, potentially leaving you liable for costly secondary damage.
The steering kingpin is a small component with an enormous responsibility. The SANY 60335146 Kingpin Assembly represents the definitive solution for restoring front-end integrity to your truck. By choosing this genuine OEM part, you are not just fixing a wear item; you are reinvesting in the foundational safety and handling characteristics of your vehicle.
Do not allow a substandard pivot point to compromise the control of a multi-ton truck. Ensure predictable handling, extend tire life, and drive with confidence by specifying the authentic SANY part number 60335146 for your next front-end overhaul.
Steer with certainty. Choose genuine SANY durability.
