Carburized to a depth of 0.6‑0.8 mm, the tappet rod achieves 58‑62 HRC surface hardness, providing exceptional wear resistance against constant camshaft and rocker arm contact.
Ball and socket ends are profile‑ground to exacting tolerances, ensuring zero‑play engagement with tappets and rocker arms for precise valve timing.
Engineered to withstand compressive loads exceeding 15 kN, the rod maintains structural integrity under extreme engine operating conditions.
Full‑length carburization and shot peening treatment eliminates stress risers, ensuring millions of reliable actuation cycles without fatigue failure.
This genuine tappet rod is the factory‑specified valvetrain component for the following SINOTRUK Howo engine families:
The WG9719360063 Tappet Rod is manufactured from high‑quality 20MnCr5 alloy steel, a material renowned for its exceptional core toughness and response to carburizing heat treatment. The manufacturing process begins with precision cold‑heading to form the blank, followed by controlled‑atmosphere carburizing that creates a hard, wear‑resistant surface while maintaining a ductile core capable of absorbing shock loads. After carburizing, the rod undergoes a quenching and tempering process to refine the grain structure, followed by a shot‑peening operation that induces beneficial compressive stresses, significantly improving fatigue life.
In heavy‑duty diesel engines, the tappet rod (or pushrod) is responsible for transmitting camshaft motion to the rocker arm, which opens and closes the valves. A bent, worn, or improperly hardened pushrod can lead to incorrect valve timing, loss of power, increased emissions, and catastrophic engine failure. The WG9719360063 addresses these risks with its precision‑ground ball ends that fit perfectly into the tappet socket and rocker arm recess, eliminating play and ensuring consistent valve lift. Fleet data shows that using genuine tappet rods reduces valvetrain‑related failures by over 90% compared to aftermarket alternatives.
Installation of this component requires attention to detail. The tappet rod must be installed with the correct orientation (ball ends properly seated), and the engine should be rotated through several cycles to verify that all rods are properly aligned before final torque of the rocker shaft. Using a genuine part ensures that the exact length and end geometry match the original engine specification, eliminating the need for shimming or adjustment. For complete engine overhauls, it is recommended to replace all tappet rods as a set to ensure uniform wear characteristics.
Quality control for the WG9719360063 includes 100% dimensional inspection using laser micrometers to verify length, diameter, and straightness. Each rod is also tested for surface hardness using Rockwell testing, with samples from each batch subjected to metallographic examination to verify case depth and microstructure. Random samples undergo compressive load testing to 20 kN to ensure structural integrity, and a 10 million cycle fatigue test on a dedicated pushrod testing machine validates long‑term durability.
Environmental sustainability is integrated into the manufacturing process. The steel used contains over 70% recycled content, and the carburizing process uses energy‑efficient electric furnaces with heat recovery systems that reduce CO₂ emissions by 30% compared to conventional methods. Scrap material from cold‑heading and grinding operations is collected and returned to steel mills for remelting, achieving a 96% material utilization rate. By choosing this genuine component, you support environmentally responsible production without compromising on performance.
For fleet maintenance departments, the WG9719360063 is available individually or in bulk packs of 12, 24, and 48 units (typical engine quantities). Each rod is individually packaged in a protective tube to prevent surface damage during shipping. A QR code on the packaging provides access to the installation torque specifications, engine timing diagrams, and a video guide for proper valvetrain assembly. Bulk orders are eligible for volume discounts and can be shipped directly from regional distribution centers.
Field performance data collected from over 2,000 SINOTRUK Howo engines operating in mining, logging, and long‑haul applications shows that the WG9719360063 tappet rod has a service life exceeding 1,500,000 kilometers with no reported failures. Fleet managers have reported that standardizing on this genuine pushrod has virtually eliminated valvetrain noise issues and valve timing drift, maintaining optimal engine performance and fuel economy throughout the engine’s life.
When ordering, verify that your engine model and valve configuration match the pushrod specifications. The WG9719360063 is designed for the WD615 and WD618 engine families used in SINOTRUK Howo vehicles from 2008 onward. For engines with different specifications, refer to the vehicle’s parts manual. Our technical support team is available through authorized dealer channels to assist with any compatibility questions regarding specific engine variants or valvetrain configurations.
In summary, the WG9719360063 Tappet Rod is the definitive valvetrain component for SINOTRUK Howo engines. Its precision manufacturing, robust heat treatment, and fatigue‑resistant design ensure consistent valve actuation, optimal engine performance, and extended service life. By investing in this genuine component, you protect your engine’s valvetrain, maintain fuel efficiency, and ensure reliable operation over millions of kilometers.
During engine service, inspect the WG9719360063 tappet rod for signs of bending, pitting, or excessive end wear. Roll the rod on a flat surface to check for straightness; replace if any deviation is visible.
Always replace tappet rods in sets if any are damaged. Clean oil passages thoroughly before installation. Lubricate ends with assembly oil during reassembly.
Aftermarket pushrods often use lower‑grade steel, lack proper heat treatment, or have poorly finished ends that wear rapidly, leading to valve clearance issues and engine noise. The genuine WG9719360063 is manufactured from certified alloy steel with precision‑ground ends and full carburization, meeting SINOTRUK’s stringent durability requirements. Counterfeit rods may be undersized or have incorrect length, causing improper valve timing. With the OEM tappet rod, you receive a fully traceable, fatigue‑tested component engineered to match the original engine specification.
Preparation: Clean the tappet bores and rocker arm sockets. Apply clean engine oil to both ends of the tappet rod. Ensure the engine is at top dead center on the cylinder being serviced.
Installation: Insert the rod with the ball ends properly seated. Rotate the engine through two full revolutions to verify that all pushrods are seated correctly and there is no binding.
After installation, adjust valve clearances according to the manufacturer’s specifications. Run the engine and listen for unusual noise; if any tapping is present, re‑check valve adjustment and pushrod seating.
The combination of carburization, shot peening, and precision grinding yields a pushrod capable of withstanding over 50 million actuation cycles without fatigue failure.
The alloy steel maintains dimensional stability across the full operating temperature range, preventing expansion‑induced valve clearance changes.
The steel used contains over 70% recycled content. All machining scrap and swarf are collected and returned to steel mills for remelting, achieving 97% material utilization.
The heat treatment facility uses energy‑efficient electric furnaces with heat recovery systems, reducing CO₂ emissions by 30% compared to conventional methods.
