OEM 160102130003A054 Two-stage Oil Pump – Genuine SANY Lubrication System

The genuine SANY parts reference 160102130003A054 is the Two‑stage Oil Pump, a precision‑engineered lubrication component that supplies pressurized engine oil to all critical bearings and moving parts in SANY heavy‑duty diesel engines. The 160102130003A054 two‑stage oil pump delivers high flow at low engine speeds for immediate lubrication and maintains stable pressure at high RPM, protecting the crankshaft, camshaft, turbocharger, and connecting rods. Manufactured from high‑strength cast iron and precision‑machined steel gears, each 160102130003A054 unit is 100% tested for flow rate and pressure, guaranteeing reliable operation in Actlon dump trucks, SY excavators, and SW wheel loaders.

The two‑stage design incorporates a primary high‑volume gear set and a secondary pressure‑maintaining set, ensuring oil delivery even under extreme engine loads. Trust only genuine SANY oil pumps for your engine rebuilds.

Design and Operation of Two‑stage Oil Pump 160102130003A054

The two‑stage oil pump 160102130003A054 consists of a cast iron housing, two gear sets (primary and secondary), a pressure relief valve, and a drive gear. The primary gear set provides high volume (up to 150 L/min) to fill the oil galleries quickly during cold starts. The secondary stage maintains stable pressure (5.0–7.0 bar) across the engine speed range, preventing oil starvation at high RPM.

The pump is driven directly by the crankshaft via a gear or chain. The gears are manufactured from case‑hardened alloy steel (58–62 HRC) and precision‑ground to ensure minimal clearance (0.03–0.08 mm) for high volumetric efficiency. The relief valve opens at 7.5 ±0.5 bar to prevent over‑pressurization of the oil system.

Every genuine 160102130003A054 pump is tested for flow rate at three engine speeds (800, 1,800, and 2,200 RPM) and pressure stability. The housing is inspected for porosity, and the gears are 100% inspected for tooth profile and surface finish. A batch code is stamped on the housing for traceability.

Critical Role in SANY Engine Lubrication System

The oil pump 160102130003A054 is the heart of the SANY engine lubrication system. It draws oil from the pan through a pick‑up tube and forces it through the full‑flow oil filter, then to the main oil gallery. From there, oil is distributed to the crankshaft main bearings, connecting rod bearings, camshaft bearings, rocker arms, turbocharger, and piston cooling jets.

A failing pump can cause low oil pressure, triggering the warning lamp and potentially damaging bearings within minutes. Symptoms include noisy lifters, fluctuating oil pressure gauge, and increased oil temperature. Always replace the oil pump during a major engine overhaul.

In D12 engines producing 2,150 N·m of torque, the oil pump must deliver consistent flow even at low idle. The two‑stage design ensures that the turbocharger receives adequate oil during high‑load operation, preventing coking and bearing failure.

Installation of Two‑stage Oil Pump 160102130003A054

Before installing the oil pump 160102130003A054, clean the mounting surface on the engine block and inspect the drive gear for wear. Prime the pump by filling it with clean engine oil through the outlet port. Lubricate the gears and bushings with assembly lube. Install a new gasket or o‑ring if specified.

Torque the mounting bolts to the specified value (typically 25–30 Nm for M8 bolts) in a star pattern. After installation, perform an oil pressure test by cranking the engine with the injection disabled until the pressure gauge shows at least 2 bar.

Never reuse an old oil pump. Gear wear reduces volumetric efficiency and can cause low oil pressure. Always replace the pump when rebuilding the engine or if any metal debris is found in the oil pan.

Signs of a Failing Oil Pump

A failing oil pump 160102130003A054 will show low oil pressure at idle or high RPM, a fluctuating oil pressure gauge, and increased engine noise (valve clatter). The oil pressure warning light may illuminate intermittently. In severe cases, the pump can seize, causing immediate engine failure.

Inspect the pump housing for cracks, the gears for scoring or pitting, and the relief valve for sticking. If any damage is found, replace the entire pump assembly. Do not attempt to rebuild the pump with non‑genuine parts.

During oil changes, examine the drained oil for metallic particles. If particles are found, the pump may be self‑destructing – replace it immediately.

Quality Assurance and Traceability

Every two‑stage oil pump 160102130003A054 is manufactured in an IATF 16949 certified facility. The housing is pressure‑tested for porosity, and the gears are 100% inspected for tooth profile and hardness. Each pump is flow‑tested on a calibrated bench at three engine speeds.

A batch code and flow test data are recorded. A Certificate of Conformance is available for bulk orders. Third‑party audits ensure compliance with ISO 9001:2015.

Field Performance of Genuine SANY Two‑stage Oil Pump

Field data from mining operations shows that genuine 160102130003A054 oil pumps maintain rated flow and pressure for over 15,000 operating hours. Aftermarket pumps often fail due to poor gear metallurgy or incorrect housing clearances, causing pressure drop within 5,000 hours.

The two‑stage design ensures that engine bearings survive cold starts even in Arctic conditions (–40°C). Fleet owners report zero oil‑pressure‑related failures when using genuine SANY pumps during engine overhauls.
