I've got a LX565 that has an engine with an unserviceable crank. I'm in Australia so I think its going to be virtually impossible to find another Shibaura N844 to put in so my intention is to find a diesel out of a car that is a similar capacity and adapt it to fit. I have a few questions though that someone may be able to answer: 1. It appears that the cooling fan on the original engine blows from the engine backward past the oil cooler/radiator to the outside. Can anyone confirm this? If so that's opposite to a conventional car engine cooling fan and would it be a problem if the new engine has a fan that sucks air past the radiator and oil cooler. It would mean hotter air is being blown over the oil cooler than if it is going the other way. 2. Diesel engines are a bit harder to get hold of than petrol engines. The problem with using a petrol engine would be how to set up a governor to maintain constant rpm. Is there a simple solution to do this or should I just stick to the idea of using a diesel?
