Fuel Shut Off Solenoid 300511-00005 for Doosan Engine Excavator Construction

Product Details

Product Overview

This Fuel Shut Off Solenoid, reference number 300511-00005, is a critical component designed for Doosan diesel engines commonly found in heavy construction equipment. As a precision electro-mechanical device, it controls the fuel supply to the injection pump, ensuring the engine stops reliably when the ignition is turned off. This solenoid is engineered to meet OEM specifications for fit and function.

While primarily associated with Doosan excavators and loaders, this solenoid is also compatible with various industrial, agricultural, genset, and marine applications that utilize the same engine platform. It serves as a direct replacement part, helping to restore proper engine shut-off functionality and prevent fuel system issues such as run-on or hard starting.

Key Features & Benefits

FAQ

Q: How do I verify if this solenoid fits my Doosan engine?
A: First, check the part number on your existing solenoid. If it matches 300511-00005, it is a direct fit. You should also verify the voltage of your electrical system (12V or 24V) and compare the mounting bracket and plunger length to your old unit.

Q: What are the common symptoms of a failing fuel shut off solenoid?
A: Common signs include the engine failing to start, the engine continuing to run after the key is turned off (run-on), intermittent stalling, or a “clicking” sound without the engine shutting down. Testing the solenoid with a multimeter can confirm coil resistance.

Q: Can I install this solenoid myself, or do I need a mechanic?
A: Installation is typically straightforward for a competent technician. It involves disconnecting the battery, removing the old solenoid (usually two bolts), transferring the plunger or connector if needed, and installing the new unit. However, if you are not experienced with fuel systems, professional installation is recommended to avoid air ingress or electrical damage.
