Exhaust valve for Kubota D1403 D1503 D1703 D1803 V1903 V2003 V2203 V2403, F2503, F2803 engines.
 
Manufactured specially to our own specification with a slot machined into the head of the valve to facilitate lapping. Using a screwdriver inserted into the slot makes it easier than using the traditional rubber sucker that we have found no longer reliably adheres to the valve.
