This is a new, genuine Kubota 1G939-60012 solenoid assembly. Kubota parts sellers describe it as a 12 V fuel solenoid actuator for 03 series engines, and it replaces the earlier 1G939-60010. Genuine-parts dealers list it as a stop solenoid for the V2203, and parts sellers cross the 1G939-60010 to V2203 and D1503 engines.

Kubota’s own tractors and excavators with 03 series engines normally use the 1A021-60017 stop solenoid, not this one. Order this part by the number on your old solenoid or by your engine serial number, not by engine model alone. A failing fuel solenoid usually shows up as an engine that cranks but will not start, starts and then dies, or will not shut off.

Specifications

Fits / Applications

• Kubota V2203 engines (select builds; confirm by old part number)
• Kubota D1503 engines (select builds; confirm by old part number)

Compare the old and new solenoid side by side before you install: mounting, plunger and connector must match. Check the fuse, wiring and stop linkage first, and find the cause if the old coil burned out.
