Product Overview
The injector meters and atomizes diesel fuel into the cylinder. Wear, contamination or nozzle damage can create hard starting, rough running, excessive smoke, cylinder imbalance and loss of power, although pump timing, compression and fuel quality should be checked during diagnosis.
Kubota L-series machines can use different engine variants across model and serial ranges. Confirm the injector number on the existing unit or in the Kubota parts catalog before ordering, especially when replacing a full set.

Frequently Asked Questions
