Kubota V2403-CR-TIE4B EGR Valve Assembly 1J808-62703 (Genuine)

Kubota EGR Valve Assembly 1J808-62703 (Genuine OEM)

This is a genuine Kubota EGR valve assembly, part number 1J808-62703, listed in the Kubota parts system as VALVE,ASSY(EGR). The EGR (exhaust gas recirculation) valve meters cooled exhaust gas back into the intake to control combustion temperatures and NOx emissions on Kubota’s electronically controlled common rail diesels. When the valve sticks, carbons up, or the actuator fails, you typically see rough idle, low power, smoke, and EGR fault codes. This is a new genuine Kubota assembly, not an aftermarket copy, supplied by Valley Fuel Injection & Turbo, an authorized Kubota dealer in Woodland, California.

Application & Fitment

Kubota’s parts book for the V2403-CR-TIE4B-KEA-1 common rail engine lists this EGR valve from engine serial 7HC0001, ref. 050, qty 1. We do not list machine models for it. Kubota uses several EGR valves on these engines, so the match has to be made by engine serial number.

Kubota builds several EGR valve assemblies with similar part numbers for other engine specifications (for example 1J807-62703 and 1J897-62703), and Kubota does not list them as interchangeable. Because fitment for this number comes from catalog diagram placement rather than a published fits-model list, we recommend a quick serial number check before you order. Call us with your engine model and engine serial number and we will verify the exact part for your machine in the Kubota parts system. We stock and source the full range of genuine parts through our Kubota engine sales, parts, and service department.

Frequently Asked Questions

What equipment does Kubota EGR valve 1J808-62703 fit?

Kubota’s parts book lists 1J808-62703 on the V2403-CR-TIE4B-KEA-1 common rail engine from serial 7HC0001, and we do not list machine models for it. Because Kubota uses different EGR valve numbers for different engine specs, confirm fitment by engine model and serial number before you order; we will help you match it at no charge. If your engine or machine is not listed here, call us anyway and we will look it up.

What are the symptoms of a failing EGR valve on a Kubota common rail engine?

Common signs include rough or hunting idle, power loss, smoke, poor fuel economy, and EGR flow or position fault codes. On late-emissions engines a stuck EGR valve can also trigger derates and aftertreatment trouble. If your engine is also throwing injector or rail pressure codes, our shop performs complete common rail system diagnosis and repair, so we can help you confirm whether the EGR valve is actually the problem before you spend the money.
