Manufactured from a high-strength steel backing with a multi-layer anti-friction bearing surface, this connecting rod lower bearing is produced to exact OEM dimensions. Its robust construction maintains correct wall thickness, crush height and locating tab geometry, resists heavy combustion loads, vibration, heat and oil degradation, and performs reliably in constant commercial truck service.
OEM VG1246030012 • Lower connecting rod bearing • Multi-layer bearing surface • Precise crush height • Direct OEM fit
This lower connecting rod bearing is a critical chassis engine bearing installed in the lower half of the connecting rod big-end bore on SINOTRUK Howo trucks. It supports the crankshaft connecting rod journal, maintains the oil film and carries the firing load transferred through the piston and connecting rod.
The bearing shell is manufactured to exact OEM dimensions. Wall thickness, crush height and locating tab geometry all match the factory specification, so it seats correctly in the connecting rod cap and maintains the specified oil clearance under load.
The lower shell works with the grooved upper shell to complete the bearing pair, ensuring pressurised oil reaches the connecting rod journal and forms a stable lubricating film during high-load and high-temperature operation.
Fitting a new VG1246030012 Connecting Rod Lower Bearing restores correct journal support, stable oil pressure and reliable power transfer. It is a durable repair that protects the crankshaft, connecting rod and piston assembly from accelerated wear and seizure.
This lower connecting rod bearing is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it fits the original connecting rod big-end cap and works with the matching upper bearing shell without modification.
The bearing is essential in applications where reliable connecting rod support and stable oil pressure are critical, such as long-haul transport, construction, mining and municipal service. In these duties, it must resist heavy combustion loads, vibration, heat and oil contamination.
When replacing the lower bearing shell, it is recommended to inspect the crankshaft connecting rod journal, connecting rod bore, upper bearing shell, piston pin and oil passages for wear or damage. This part is designed to work with the factory engine assembly for correct fit and reliable operation.
For fleets with multiple HOWO trucks, standardising on the VG1246030012 Connecting Rod Lower Bearing simplifies maintenance and ensures the correct part is available for scheduled service or emergency repairs.
Replacing the VG1246030012 Connecting Rod Lower Bearing is a precision engine repair that requires proper measuring tools and a clean work area. This work should be performed by a qualified technician.
Remove the connecting rod cap, clean the cap bore and inspect the crankshaft journal for scoring, taper or ovality. Check the new bearing shell for correct size, locating tab and surface condition before installation.
Fit the lower bearing shell into the connecting rod cap, lubricate the bearing surface with clean engine oil and reinstall the cap. Tighten the connecting rod bolts to the OEM torque and check the oil clearance with plastigauge or a micrometer.
Reassemble the engine, refill with the specified engine oil and run the engine while checking oil pressure. During routine service, monitor oil pressure and inspect the oil for metal debris that could indicate bearing wear.
This lower connecting rod bearing is manufactured in an ISO 9001-certified facility using a high-strength backing and a multi-layer anti-friction bearing surface. Incoming materials are checked for thickness, hardness, bond strength and surface quality before production begins.
Each bearing is formed, machined and finished on precision equipment, then inspected for wall thickness, crush height, locating tab geometry and surface finish. Every batch is dimensionally checked, and samples receive a fit and load test before packing.
Batch samples undergo oil immersion, thermal cycling, fatigue and wear testing to confirm long-term reliability in heavy-duty truck use. These checks help ensure the bearing performs in the tough conditions Howo trucks face every day.
This lower connecting rod bearing is covered by a 12-month warranty against material and workmanship defects. Strict quality control means every unit matches the fit, function and durability of the original factory part.
The VG1246030012 Connecting Rod Lower Bearing is a vital component for maintaining correct journal support, stable oil pressure and reliable power transfer on your Howo truck. A worn or damaged lower bearing shell can cause knocking, low oil pressure and costly crankshaft or connecting rod damage.
Manufactured from quality materials with a multi-layer bearing surface and precise crush height, this lower bearing shell offers dependable performance and long service life. Its direct-fit design keeps installation simple and works with the factory connecting rod.
Fleet operators benefit from reduced engine repair downtime, lower maintenance costs and improved vehicle availability. Owner-operators gain confidence from a bearing that meets strict OEM standards and is backed by a 12-month warranty.
