Not all kubota engines are "the same". There's a few different variants, even of the exact same displacement engine. Lot of times the governors and injection pumps can vary from engine to engine depending on what application it's for. Compression ratios can vary. Exhaust an intake manifolding can vary. Turbo vs naturally aspirated blocks-they're different too (turbo blocks are drilled for the oil return). Water pumps can be different depending on what it's going into or coming out of (if someone was to buy a donor engine). Crankshaft pulley. Etc.
If you end up having to replace it, keep those things in mind. Kubota has a model number on each engine, for instance V2403-DI-E2MA, and each number/letter has a meaning that designates it's application among other things.
I'm one of those who, when I went into the business, I thought many of the Kubota engines were interchangeable. Had a guy with I think an L2900 that needed an engine (broken crankshaft). He found the same displacement engine that came out of a reefer unit. I go to install it, bellhousing different. Flywheel different. BUNCH of stuff was different. I had to swap the stuff from his old engine, got it bolted to the tractor, started it and find out that it runs 1800 RPM continually, no idle. Thats how I found out that the governor is different, and the linkages. And the injection pump as well. By time it was all said & done, the guy put nearly $3000 into a used engine to make it "work" on his tractor. At that time, brand new engine from Kubota was $3400.
Let us know how the sealer works...I'm curious.
