FAQ

Common Questions

What is the difference between a "lamp timer" and a "timer relay" for glow plugs?

On Kubota engines, the lamp timer (also called a glow indicator timer) serves two functions: it controls how long the glow plugs are powered during pre-heat, and it illuminates the glow plug warning light on the dash to tell the operator when to crank. The term "lamp timer" reflects this dual function. It's the same type of component as a timer relay — just Kubota's specific naming for the part.

My Kubota V2203 starts fine when warm but needs several seconds of extra cranking in the cold — is this the timer?

That's a textbook symptom of reduced glow plug pre-heat time. When the timer relay starts to fail, it may not power the glow plugs for the full pre-heat duration, or not at all. Test by checking voltage at the glow plug bus during the pre-heat cycle. If voltage drops off too quickly or doesn't appear, replace the timer. At $15.99, it's one of the cheapest first steps in cold-start diagnosis.

Does this lamp timer fit Kubota engines in Bobcat, John Deere, and other equipment that uses Kubota engines?

Yes. Many Bobcat skid steers, Toro, Jacobsen, and industrial equipment use Kubota V-series and D-series engines. As long as the Kubota engine model matches the compatibility list (V3600 down to D662), this timer fits regardless of what brand of machine the engine is installed in. Confirm by matching part number 15694-65992 or S81NL on the existing timer.
