The A30-1011020A oil pump features a precision‑machined cast iron housing and heat‑treated, case‑hardened gears that maintain exact meshing tolerances over thousands of operating hours. This design minimizes internal leakage and ensures consistent oil pressure from idle to maximum engine speed. The gear profiles are optimized for quiet operation and high volumetric efficiency, delivering the flow required to protect main bearings, connecting rods, and turbochargers. The pump includes an integrated pressure relief valve calibrated to open at the specified pressure, safeguarding the engine against over‑pressurization during cold starts.
Every A30-1011020A pump undergoes strict dimensional and material verification. The housing is pressure‑tested to ensure no porosity or cracks, while the gear teeth are inspected for surface finish and hardness. The pump is then assembled with precision bearings and seals, and each unit is flow‑tested to verify performance against OEM specifications. This meticulous quality control guarantees that the oil pump performs flawlessly in the harsh environment of a heavy‑duty diesel engine, providing reliable lubrication for millions of cycles.

The A30-1011020A oil pump is a direct OEM replacement for the lubrication pumps used in a wide range of SINOTRUK HOWO engines, including the WD615 series (Euro‑2 to Euro‑5), the MC11 and MC13 engines found in T7H and C7H models, as well as the D10 engines. It supplies pressurized oil to the engine’s main oil gallery, from which it is distributed to crankshaft main bearings, connecting rod bearings, camshaft bearings, valve train components, and the turbocharger. A properly functioning oil pump is essential for maintaining the oil film that prevents metal‑to‑metal contact and reduces friction.
In the context of the chassis, reliable engine lubrication directly impacts the overall vehicle’s uptime. Oil pump failure can lead to rapid engine seizure, leaving a truck stranded and incurring costly repairs. By using the genuine A30-1011020A pump, you ensure that oil pressure remains within specifications, protecting not only the engine but also downstream components such as the transmission PTO (if engine‑driven) and any auxiliary equipment. Fleet operators who prioritize genuine parts report significantly lower maintenance costs and extended engine life.
When rebuilding an engine, always replace the oil pump with a new genuine A30-1011020A. Even a slightly worn pump can result in low oil pressure and premature bearing failure. Always prime the pump with clean oil before installation.
Correct installation of the A30-1011020A oil pump is critical to ensure proper lubrication and long service life. Follow these steps:
Thoroughly clean the engine block mounting surface and oil pickup tube. Inspect the pump drive gear for wear; if damaged, replace it. Ensure all old gasket material is removed.
Place a new gasket (if applicable) and position the pump onto the block. Torque mounting bolts to the specification in the service manual (typically 45‑55 Nm). Always use a torque wrench.
Before starting the engine, fill the pump housing with clean engine oil and rotate the pump gear by hand to distribute oil. This prevents dry start‑up damage.
A failing oil pump can lead to catastrophic engine damage. Common symptoms include low oil pressure warning lights, noisy valve train (due to insufficient oil), and increased operating temperatures. During engine overhauls, it is standard practice to replace the oil pump regardless of its apparent condition, because internal clearances can open up over time, reducing efficiency. If you notice metal particles in the oil during changes, inspect the pump gears for scoring. Any sign of wear, such as pitting on gear teeth or scuffing on the housing bore, indicates that replacement with a genuine A30-1011020A is necessary.
Ignoring oil pump wear can result in bearing spin, crankshaft damage, and complete engine failure. Timely replacement with a genuine A30-1011020A restores proper oil flow and protects your investment.
Precision‑ground gears and calibrated relief valve ensure consistent oil pressure under all operating conditions, protecting critical engine components.
By maintaining proper lubrication, the genuine pump reduces wear on bearings and turbochargers, delaying overhauls and lowering total cost of ownership.
Manufactured to original specifications, the pump bolts on without modification and delivers the exact flow and pressure required by your Howo engine.
To maximize the service life of your A30-1011020A oil pump, follow these best practices:
By adhering to these guidelines, you ensure that the A30-1011020A pump performs optimally throughout its intended service interval.
Aftermarket oil pumps often use inferior materials and lack the precise machining of genuine components. They may have incorrect gear backlash, housing porosity, or improperly calibrated relief valves, leading to low oil pressure or premature failure. The genuine A30-1011020A is manufactured to the exact specifications of the original equipment, using high‑grade cast iron and case‑hardened steel gears that withstand the rigors of heavy‑duty operation. Each pump is tested for flow and pressure before leaving the factory.
By choosing authentic SINOTRUK HOWO parts, you ensure that your engine receives the correct oil volume and pressure at all times. This directly translates to longer engine life, reduced maintenance costs, and higher resale value. The Sinotruk howo parts catalog includes a full range of engine and chassis components engineered for maximum reliability.
The A30-1011020A oil pump is used across a wide range of Howo models: T7H, T5G, A7, and traditional Howo‑7 series. It fits engines with part numbers WD615.47, WD615.69, MC11.36, MC13.48, and D10.34. Always verify the engine serial number and the pump drive configuration (gear‑driven from crankshaft) to ensure proper fit.
Each A30-1011020A is individually packaged with a protective coating to prevent corrosion during storage. The package includes a new gasket and the necessary mounting bolts (if applicable). For bulk orders, the pumps are supplied in sealed cartons with the OEM logo and batch traceability.
Production of the A30-1011020A takes place in ISO/TS 16949 certified facilities, using precision CNC machining centers and in‑process gauging.
