1A021-60017 Fuel Shut-Off Solenoid for Kubota KX91-3, KX121-3, KX161-3

   The 1A021-60017 is a 12V, 3-wire solenoid designed for Kubota’s highly reliable "Super 03" and "03-M" series engines. This specific 3-wire design features a "Pull" coil and a "Hold" coil. The "Pull" coil provides the high-amperage force needed to move the fuel lever during startup, while the "Hold" coil uses low amperage to keep the engine running without overheating the solenoid. Failure of this component usually results in an engine that either won't start or won't turn off with the key.

Q&A Section

Q1: My engine starts but dies as soon as I release the key. Is the 1A021-60017 the problem?

A: Very likely. This symptom usually indicates that the "Pull" coil is working, but the "Hold" coil has failed. The solenoid pulls the fuel rack to start the engine, but cannot hold it in place once the key returns to the "On" position.

Q2: Can I manually bypass this solenoid if I'm stuck on a job site?

A: In an emergency, you can usually remove the solenoid and manually move the fuel rack to the run position, but you will have to use the manual stop lever on the injection pump to kill the engine. Warning: This bypasses all safety shut-offs (like low oil pressure protection).

Q3: Does the 1A021-60017 require any adjustment during installation?

A: No. It is a direct-mount component. Simply ensure the mounting surface is clean and the plunger is correctly aligned with the fuel pump lever before tightening the bolts.
