Sorry John but I have to disagree with your reply to the automotive anti-freeze being used in a diesel engine. The corrosion inhibitors in antifreeze used for automotive applications are different than those used in heavy duty diesel engines. Electrolosis and/or cavitation (pitting) of the cylinder sleeves can and does occur in diesel engines. In fact I have actually seen cylinder sleeves pitted clear through from the anti-freeze side-not the piston side. Usually this is due to the additives breaking down after a short while and the pitting can be quite severe in suprisingly short amount of time. I have also seen diesel engines with the sleeves so rusted in that it is nearly impossible to remove them. All due to the wrong antifreeze. My thought is if you are going to skimp on something don't do it on something that is going to be in your engine for an extended period of time. It's not woth the few buck you save initially. Get a heavy duty anti-freeze labeled for diesel engines. Look for borate/nitrite inhibitors in your antifreeze to prevent electrolosis/cavitation in wet sleeves.
Jon, just to satisfy my curiosity, are there no sleeves or are they press fit sleeves? And is this consistent with all of the Kioti tractors or this particualr model? Excluding the Dk 65 which I understand is a perkins engine and probably is a sleeved engine.
They use to have sleeves back in the past onthe 20HP - 30HP . All the newer (I wanna say around 95 or so) have no sleeves. Main reason behind this is it just wasn't cost effective for a customer to rebuild an engine vs. buy a complete engine from Kioti. And you get more with the new engine vs rebuild.
