Shangchai (SDEC) G15-000-01+A Single-stage oil pump assembly

Product introduction

The single-stage oil pump assembly, part number G15-000-01+A, is the heart of the lubrication system of Shanghai (SDEC) G128 series 6-cylinder diesel engines. It is designed to generate the necessary pressure and continuously supply clean engine oil to all moving engine components, providing lubrication, cooling, and wear protection. This part is specifically designed to operate under extreme loads, high temperatures, and vibrations typical of heavy construction, mining, and generator equipment. Unlike non-genuine alternatives, the genuine G15-000-01+A oil pump guarantees stable lubrication system operation, engine protection, and extended service life.

Materials and technical characteristics

The main feature of the Shangchai G15-000-01+A oil pump is the use of high-quality materials and modern manufacturing technologies, which gives it exceptional performance properties:

• Pump body and cover: Made of high-strength alloy cast iron with high density and internal pressure resistance, preventing deformation and oil leakage.

• Gears: Made of high-strength alloy steel, heat-treated (hardened and case-hardened) and precision-ground. This ensures high hardness, wear resistance, and minimal gear clearance, ensuring maximum performance and stable oil pressure.

• Bearings and shafts: Equipped with high-quality needle or plain bearings that are resistant to high loads and wear, ensuring a long service life of the pump.

• Sealing system: A set of high-quality nitrile rubber (NBR) seals ensures absolute tightness and prevents oil leaks.

• Pressure regulator: Built-in precision pressure reducing valve that maintains stable oil pressure in the system within specified limits, protecting the engine from overloads and oil starvation.

• Technical Parameters:

• Type: Single-stage gear oil pump

• Article: G15-000-01+A

• Weight: 13.5 kg

• Package dimensions: 340×300×260 mm

• Operating temperature: -40°C to 120°C

• Maximum working pressure: up to 0.8 MPa (standard for G128 engines)

• Compatibility: Shangchai G128 engines and other models with corresponding parameters.

Each pump undergoes multi-stage quality control at the SDEC factory, including performance, leakage, pressure stability, and wear resistance testing, which is confirmed by certificates of conformity.

Scope of application

Oil pump G15-000-01+A is designed for installation in the following types of equipment with Shanghai G128 engines:

1. Heavy construction equipment: Bulldozers, excavators, loaders, truck cranes equipped with G128 engines.

2. Generator sets: Diesel generators based on G128 engines, used for backup and permanent power supply.

3. Freight and special transport: Heavy trucks, buses, garbage trucks, fire trucks with G128 engines.

4. Marine equipment: Small vessels, boats and auxiliary marine equipment with G128 diesel engines.

Thanks to its universal design, the pump is suitable for both initial installation on new engines and for replacing worn components during major overhauls, making it popular with both official SDEC dealers and independent service centers.

Functional purpose

The main function of the Shangchai G15-000-01+A oil pump is to create stable pressure and continuously supply engine oil to the engine lubrication system, performing the following critical tasks:

1. Lubrication: Delivers oil under pressure to all moving engine components (crankshaft and camshaft bearings, piston group, timing mechanism), reducing friction and preventing scuffing and breakage.

2. Engine cooling: Circulating oil removes excess heat from hot components (pistons, bearings), preventing overheating and burnout of parts.

3. Engine Cleaning: Removes wear debris, carbon deposits and abrasive particles from working areas, transporting them to the oil filter for cleaning.

4. Piston Group Sealing: The oil supplied by the pump fills the gaps between the piston rings and the cylinder walls, improving the sealing of the combustion chambers and increasing compression.

5. Corrosion Protection: Creates a protective oil film on the internal surfaces of the engine, preventing corrosion and oxidation.

6. Pressure stabilization: The built-in pressure regulator maintains stable oil pressure in the system at any engine speed, protecting against oil starvation during cold starts and overloads at high speeds.

Proper oil pump operation directly impacts engine reliability, power, and lifespan: failure leads to oil starvation, overheating, and catastrophic engine failure in minutes.

Advantages over non-original analogues

Many customers choose non-original analogues of the G15-000-01+A oil pump due to the lower price, but such units have a number of significant disadvantages compared to the original SDEC product:

1. Low machining accuracy: Non-genuine pumps often have deviations in the dimensions of the gears and housing, resulting in low performance, unstable oil pressure and rapid wear.

2. Low material strength: Comparative pumps are often made from low-quality cast iron and steel without the necessary heat treatment, which leads to housing deformation, gear breakage, and pump failure under load.

3. Unreliable pressure regulator: Non-original valves often do not provide stable pressure, which leads to oil starvation or overload of the lubrication system.

4. Poor sealing: Poor seals result in oil leaks, low pressure and engine contamination.

5. No warranty: Non-genuine replacements do not carry an official manufacturer's warranty, and if they fail, the user is responsible for all engine repair costs. The original G15-000-01+A pump comes with an SDEC warranty, confirming its quality.

6. Short service life: Non-original pumps often fail after just 1-2 years of operation, while the original unit retains its properties throughout the entire service life of the engine.

Installation and maintenance

Installation of the Shangchai G15-000-01+A oil pump must be performed by a qualified technician in accordance with all G128 engine repair instructions. Incorrect installation can result in leaks, unstable pressure, and engine failure, so the following steps are recommended:

1. Preparation for installation:

• Clean the mounting area on the cylinder block from dirt, rust and old oil residue.

• Check the new pump for external defects, damage to the housing and gears.

• Fill the pump internal cavities with clean engine oil before installation to ensure immediate oil supply upon start-up and to prevent dry friction.

• Check the condition of the pump drive (gear or chain) and replace it if worn.

• Install a new gasket between the pump and the cylinder block, making sure the holes are aligned correctly.

• Carefully install the new pump onto the drive, ensuring that the gears mesh correctly.

• Secure the pump to the bolts, observing the tightening sequence and the recommended tightening torque (specified in the G128 repair manual).

• Connect the oil lines to the pump, making sure the connections are tight.

• Start the engine and let it idle.

• Check the oil pressure with a gauge, making sure it meets the G128 specification.

• Visually inspect the pump body and connections for oil leaks.

• Check the engine oil level and top up to normal if necessary.

To extend the life of the pump, it is recommended to change the engine oil and oil filter regularly, use only high-quality oil that meets the SDEC specification, and maintain the engine lubrication system in a timely manner.

Conclusion

The Shangchai G15-000-01+A single-stage oil pump is a critical component of the lubrication system, ensuring reliable operation of the G128 6-cylinder diesel engines under the harshest operating conditions.
