stupid question time,,.you did indeed have water in the radiator ,,it has honestly been over looked by folx I know around here ,,.mostly because they thought someone else had put water in it while they went pik up sumthin ...and the water boy got distracted by the cows getting out or his girl friend dropping by wanting to know how a carburetor works on a diesel tractor .lol.they will cease up and lok up ,, but generally.after a natural cool down ,they will be fine with full coolant..if coolant is ok, then ,yeah that is tuf break ,,. btdt enuf to where I no longer will do bottom ends,and sleeve , piston rings , just do water pumps head gaskets ,injectors,. ,,don't kik yourself or beat yourself up . I took down a yanmar 2220 3 times before it finally run like it should.. after 12 hours see if the motor cranks normal . if so,,. if you are like me you will want to start it and see if it does it again , and possibly really phuk the motor up... lol ,.what I would do is add a couple quarts of atf , and perhaps some engine restorer ,. if it ceases again ,, try hand cranking the motor rite after ceasing , half hour later, 1 hour later and so forth,.just to judge whether it is crank or cam bearing,., imho, that idea is like playing Russian roultte ,,..to be on the safe side you would do well to meticulously remove and inspect each bearing.. .
