252-5165 2525165 B2G005 Diesel Engine Turbocharger for D6R D6R III D6T D7R XR Bulldozer Turbo Assembly

The 252-5165 B2G005 Turbocharger is a replacement diesel engine turbocharger assembly designed for compatible Caterpillar C9 engine applications, including selected D6R, D6R III, D6T, and D7R crawler bulldozers.

Also known as a Diesel Engine Turbocharger, B2G Turbo Assembly, Exhaust Gas Turbocharger, or Bulldozer Engine Turbo, this component is designed to increase the amount of compressed air supplied to the diesel engine intake system.

The turbocharger uses exhaust gas energy to drive a turbine wheel, which powers the compressor wheel to deliver pressurized intake air into the engine.

A correctly matched and properly functioning turbocharger supports the engine's designed power output, combustion performance, and operating efficiency.

The B2G005 turbocharger features a silver-colored compressor housing, dark cast-metal turbine housing, pneumatic actuator assembly, yellow actuator hose, machined connection interfaces, and protective covers over the intake and outlet openings.

JISION supplies diesel engine turbochargers, engine fuel system components, hydraulic parts, and construction machinery replacement parts to equipment owners, bulldozer maintenance workshops, construction contractors, and international spare parts distributors.

Designed to use engine exhaust gas energy to drive the turbine wheel and generate compressed intake air for compatible diesel engines.

The B2G005 turbocharger is offered for compatible Caterpillar C9 engine applications requiring the corresponding turbocharger configuration.

Features a robust cast-metal turbine housing intended for high-temperature diesel engine exhaust applications.

Equipped with a compressor housing and internal rotating compressor assembly designed to deliver compressed intake air.

Includes an external actuator and hose arrangement associated with the turbocharger's control mechanism.

Features machined inlet and outlet connections for installation with the corresponding engine intake and exhaust components.

The pictured turbocharger includes protective covers intended to reduce contamination during storage, handling, and transportation.

Offered as a replacement component for compatible diesel engine turbocharger repairs, engine servicing, and construction machinery maintenance.

Correct turbocharger installation is important for diesel engine reliability and turbocharger service life.

Before installation:

1. Verify the original turbocharger part number and engine serial number.

2. Inspect the engine air intake and exhaust systems for contamination or damage.

3. Check the turbocharger oil supply and return lines for blockages or restrictions.

4. Confirm the replacement turbocharger housing and actuator configuration.

5. Inspect the turbocharger mounting surfaces and connection flanges.

6. Replace specified gaskets and sealing components.

7. Pre-lubricate the turbocharger according to the manufacturer's installation instructions.

8. Install the turbocharger using the specified tightening torque.

9. Start the engine according to the manufacturer's initial startup procedure.
