Never again....Swapped out a Yanmar NTE-88 that was mistreated by a contractor for a Kubota 1903 ..Had to change/fabricate everything to make it work....Motor mounts , radiator, throttle bellcrank as the throttle worked the wrong way, change pump mounting bolt holes by 7 degrees, manual gauges , shut-off cable , oil cooler mounting , exhaust, air cleaner.Made an adapter to replace oil filter with a machined roundstock , drilled channeled and remote filter mount and hydraulic hoses....Kinda like building a hotrod.... many hours later finally done..Works well..Reason for swap as opposed to rebuild ?? Parts list was 3800.00 without doing the head and injector pump, starter.. Kubota was in an unused boring machine with only 40 hours on it....
