If your Bobcat skid steer loader won't start or shuts off unexpectedly, the fuel shut-off solenoid might be the problem. This is a brand new replacement solenoid that fits a bunch of popular Bobcat models like the S130, S150, S160, S175, S185, S205, and S450. The part number is 6691498. This little electronic part controls the flow of fuel to the engine – when it gets power, it opens to allow fuel; when you turn the key off, it closes to stop the engine. They can wear out or fail. Replacing it is usually a direct swap: disconnect the old one and connect the new one. It's a common repair that can get your machine back up and running quickly. Always double-check it matches your specific Bobcat model before ordering.
