FAQs

Q: What engines does 1G577-60010 fuel shutoff solenoid fit?

A: It works for Kubota V3300, V3300-DI-T, V3800 and V3800-T diesel engines.

Q: What Bobcat machines are compatible with this solenoid?

A: It fits Bobcat skid steer loaders and excavators including S220, S250, S300, S330, S750, S770, S850, T250, T300, T320, T750, T770, T870, A300, A770, V417.

Q: What is the dual coil working principle of this shutoff solenoid?

A: The high-current pull coil activates to open the fuel path when starting. Once the engine runs, the low-current hold coil takes over to keep the circuit open steadily. When power cuts off, fuel supply stops to shut down the engine.
