Product Introduction: A precision-machined bushing made of a high-strength copper-lead alloy. It features an internal oil groove and a lubrication hole to ensure continuous oil flow, reducing friction and wear between the connecting rod small end and the piston pin. The bushing is designed for a press-fit installation, ensuring a tight, stable fit.

Function: Supports the piston pin within the connecting rod small end, reducing friction during the piston’s reciprocating motion. The lubrication system dissipates heat and prevents premature wear, while the alloy construction provides high load capacity and durability under extreme engine conditions.

Connecting Rod Bushing VG1500030077 SINOTRUK – Factory-Direct OEM Quality

When your heavy-duty engine demands precision, every micron counts. The Connecting Rod Bushing VG1500030077 is engineered to serve as the critical pivot interface between the piston pin and connecting rod small end in SINOTRUK WD615/WP10 series engines. Sourced directly from our warehouse in Jinan, China — the hometown of SINOTRUK — this bushing delivers OEM-grade fitment, superior wear resistance, and extended service life that keeps your fleet rolling without costly downtime.

At JINAN METTLEAD AUTO SALES CO., LTD., we have spent over a decade supplying genuine and OEM-equivalent SINOTRUK parts to fleet operators, workshop owners, and procurement managers across 60+ countries. This connecting rod bushing is one of our highest-demand engine components — and for good reason.

Application Scenarios

The Connecting Rod Bushing VG1500030077 is specifically designed for the small end of the connecting rod in SINOTRUK WD615 and Weichai WP10 series diesel engines. It acts as the articulating support bearing between the piston pin and the connecting rod, absorbing high-frequency oscillating loads and distributing oil film pressure evenly across the contact surface.

Compatible vehicles and engines include:

• SINOTRUK HOWO A7, HOWO 371/375/380hp heavy-duty trucks
• SINOTRUK Steyr (Sitaier) series trucks
• Weichai WD615.69 / WD615.47 / WP10.340 / WP10.375 engines
• SITRAK C7H series equipped with WD615/WP10 powertrains
• Mining dump trucks, concrete mixers, and tractor heads using the above engine platforms

Whether your trucks haul cargo across African highways, navigate Middle Eastern construction sites, or power Southeast Asian logistics corridors, this bushing ensures smooth piston articulation under extreme thermal and mechanical stress.

Features and Benefits of Connecting Rod Bushing VG1500030077

Precision-Engineered for Demanding Conditions

• Bimetallic Construction: Steel-backed copper-lead alloy lining provides exceptional load-bearing capacity and fatigue resistance under high RPM operation.
• Tight Dimensional Tolerance: Manufactured to OEM specifications (interference fit tolerance within ±0.01mm) ensuring perfect press-fit into the connecting rod small end bore.
• Optimized Oil Groove Design: Internal lubrication channels promote consistent oil film formation, reducing dry-start wear and extending bushing life beyond 300,000 km under normal operating conditions.
• Heat Dissipation: The copper alloy matrix efficiently transfers combustion-generated heat away from the piston pin interface, preventing seizure.

Frequently Asked Questions About Connecting Rod Bushing VG1500030077

What causes a connecting rod bushing VG1500030077 to fail prematurely?

The most common culprits are insufficient lubrication, contaminated engine oil carrying abrasive particles, or overheating due to coolant system failure. When the oil film breaks down, metal-to-metal contact between the piston pin and bushing surface accelerates wear exponentially. Regular oil changes with the correct viscosity grade (typically 15W-40 for WD615 engines) are your bushing’s best friend.

How do I know when the connecting rod bushing needs replacement?

Listen for a distinct knocking sound from the engine block — especially noticeable at idle or low RPM. Excessive piston pin clearance (beyond 0.06mm) measured during teardown confirms the bushing has worn past its service limit. If you notice increased oil consumption alongside the knock, the bushing is likely allowing excessive piston pin play.

Is this connecting rod bushing VG1500030077 an OEM-equivalent part?

Yes. This bushing is manufactured to the exact OEM dimensional and material specifications published by SINOTRUK for part number VG1500030077. It is a direct drop-in replacement that requires no modification to the connecting rod or piston pin.

Can I use this bushing in a Weichai WP10 engine outside of a SINOTRUK vehicle?

Absolutely. The WP10 engine family shares the same connecting rod architecture regardless of the vehicle chassis manufacturer. If your engine uses the VG1500030077 part number in its bill of materials, this bushing fits — whether installed in a SHACMAN, FOTON, or any other OEM using the Weichai WP10 platform.

What is the recommended installation method for this connecting rod bushing?

The bushing must be press-fitted into the connecting rod small end bore using a hydraulic press or dedicated bushing installation tool. Never hammer it in — uneven force can distort the bore geometry. After installation, hone the inner diameter to achieve the specified piston pin clearance of 0.03–0.05mm. Ensure the oil hole in the bushing aligns with the oil passage in the connecting rod.

Do you supply connecting rod bushings for other SINOTRUK engine models?

Yes. We carry connecting rod bushings and a full range of engine components for WD615, WP10, WP12, WP13, MC11, and MC13 engine series. Browse our complete SINOTRUK HOWO Engine Parts catalog to find your exact part number.
