Stripped the diesel engine this morning. Removed the radiator and hoses, fan, alternator and alternator mount. This cleaned up the front (right side) of the engine.

Next I removed the air filter and mounting bracket, intake hoses and muffler. The top of the engine is now a lot lower.

I removed the starter, the exhaust manifold with turbocharger and oil lines. Then removed the flywheel so the engine plate at the rear of the engine could also be removed. After taking the plate off, I replaced the flywheel and did a test fit of the manifold and turbocharger mounted so the exhaust goes down rather than up. It fits like it belongs. The turbo housing will need to be rotated so the oil still fllows from top to bottom, then the wastegate will need to be mounted 180 degrees so it still connects correctly. It will also need new oil lines, but none of these looks like a show-stopper. Doing it that way, it looks easiest (at this point) to keep the Harley starter.

I also ordered a maintenance manual from Kubota. Having the manual should make it a bit easier to figure out some of these things. With a bit of luck, they'll have a photo of the turbo mounted in the 'down' position. Then I can be certain that the parts to mount it are available.
