The VG1560037034 bearing shell features a tri‑metal construction: a steel backing for structural rigidity, a lead‑copper intermediate layer for fatigue strength, and a soft babbitt overlay that provides conformability and embeddability for foreign particles. This design ensures excellent load‑carrying capacity and seizure resistance under the high specific pressures found in turbocharged diesel engines. The bearing also incorporates precision‑machined oil grooves and holes that align with the connecting rod oil passages, guaranteeing consistent lubrication to the crankpin.
Each VG1560037034 shell is manufactured to tight tolerances (wall thickness variation < 5 microns) to maintain the correct oil clearance when installed. The parting line is precisely controlled to ensure a flush fit with the mating shell, preventing oil leakage and reducing stress concentrations. All shells are 100% inspected for dimensional accuracy, surface finish, and material integrity. This rigorous quality control guarantees that the bearing will provide millions of cycles of reliable operation under the most demanding conditions.

The VG1560037034 connecting rod bearing shell (lower) is a direct OEM replacement used in Howo engines, including the widely used WD615 series (Euro‑2 to Euro‑5), the MC11 and MC13 engines in T7H and C7H models, as well as the D10 engines. It is installed in the connecting rod big end, providing a replaceable wear surface that supports the crankshaft journal. The lower shell typically carries the highest load due to combustion pressure, making its material and precision critical for engine durability.
In heavy‑duty applications, bearing failure can lead to catastrophic engine damage. The genuine VG1560037034 shell ensures that oil clearance and surface finish meet the original design specifications, providing reliable operation under peak cylinder pressures. It is also used in remanufactured engines and during major overhauls to restore the engine’s performance and reliability.
Always replace connecting rod bearings in sets. Use plastigage to verify oil clearance during assembly. Lubricate shells with assembly lube before installation.
Correct installation of the VG1560037034 bearing shell is critical to ensure proper oil clearance and long service life. Follow these steps:
Clean the connecting rod bore and crankshaft journal thoroughly. Inspect for any damage or scoring. Measure the journal diameter and compare to specifications.
Insert the bearing shell into the rod and cap, ensuring the locating tang engages properly. Apply assembly lube to the bearing surface. Assemble the rod to the crankshaft and torque the bolts to specification in stages.
Check oil clearance using plastigage; it should be within 0.05‑0.08 mm. Rotate the crankshaft to ensure smooth movement. Prime the oil system before starting the engine.
Worn bearings can cause engine noise and low oil pressure. Common signs that replacement is needed include:
If any of these symptoms are observed, immediate replacement with genuine VG1560037034 shells is recommended. Continuing to operate with worn bearings can lead to rod failure and complete engine destruction.
The tri‑metal construction withstands peak cylinder pressures exceeding 200 bar, ensuring reliable performance in turbocharged diesel engines.
The lead‑copper layer and babbitt overlay provide excellent resistance to fatigue and wear, extending engine life.
Tight manufacturing tolerances ensure correct oil clearance, reducing friction and preventing seizure.
To maximize the service life of your VG1560037034 bearing shells, follow these best practices:
By adhering to these guidelines, you ensure that the VG1560037034 bearings perform optimally throughout their intended service interval.
Aftermarket bearing shells are often made with inferior materials and lack the precise dimensional control of genuine parts. They may have incorrect wall thickness, leading to improper oil clearance, or poor overlay adhesion, resulting in premature fatigue. The genuine VG1560037034 is manufactured to the exact specifications of the original equipment, using certified tri‑metal materials and state‑of‑the‑art plating processes. Each shell is tested for hardness, bond strength, and dimensional accuracy, guaranteeing that it will perform exactly as the original part.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its reliability and resale value. The Sinotruk howo parts catalog includes a full range of engine and chassis components engineered for maximum durability. For fleet managers and owner‑operators who demand the best, the genuine VG1560037034 is the only responsible choice.
The VG1560037034 connecting rod bearing shell (lower) is used across a wide range of Howo models: T7H, A7, and classic Howo‑7 series equipped with WD615, MC11, MC13, and D10 engines. Always verify the crankpin diameter (typically 92 mm) and the bearing width using the service manual.
Each VG1560037034 is individually wrapped in protective paper and packaged in sets of 12 shells for a complete engine set. The packaging is clearly labelled with the OEM number and batch code. For bulk orders, shells are shipped in sealed cartons with foam inserts to avoid transit damage.
Production of the VG1560037034 takes place in IATF 16949 certified facilities, using precision stamping and electroplating lines with in‑process gauging. Statistical process control ensures that wall thickness variations are kept to a minimum, far exceeding the requirements of the original design.
