OEM VG1246030011 • Upper connecting rod bearing • Multi-layer bearing surface • Oil groove accurate • Direct OEM fit
This upper connecting rod bearing is a critical chassis engine bearing installed in the upper 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, oil groove position, oil hole alignment, crush height and locating tab geometry all match the factory specification, so it seats correctly and maintains the specified oil clearance under load.
The upper shell is designed with a circumferential oil groove and oil feed hole that deliver pressurised oil to the connecting rod journal, ensuring a stable lubricating film during high-load and high-temperature operation.
Fitting a new VG1246030011 Connecting Rod Upper 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 upper 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 bore and cap 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 upper bearing shell, it is recommended to inspect the crankshaft connecting rod journal, connecting rod bore, lower 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 VG1246030011 Connecting Rod Upper Bearing simplifies maintenance and ensures the correct part is available for scheduled service or emergency repairs.
Replacing the VG1246030011 Connecting Rod Upper 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 bore and inspect the crankshaft journal for scoring, taper or ovality. Check the new bearing shell for correct size, locating tab and oil hole alignment before installation.
Fit the upper bearing shell into the connecting rod, lubricate the bearing surface with clean engine oil and install 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 upper 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, oil groove position, oil hole alignment, crush height and locating tab geometry. 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 upper 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.
