Not being the resident case expert but have worked on a hand full one thing i learned on 930's was about the heads . You said you had a LIGHT knock from the start , take a good look at the top of the piston on #1 and see if you show any signs of a valve hitting the piston . and look at your cylinder heads real close and check the numbers on them and make sure they are what is suppose to be on your engine . I had a 930 come in one time for a cracked head and i found that i had cracks in all of the heads . Called around and ONE guy said he had GOOD heads that were checked with fresh valve jobs . Well they were off and 830 and yep they bolted on but when i started it i had a knock and shut it down and pulled the heads and had valves hitting the piston . Now i am not sayen this is your problem but maybe if the valve job was not done correctly and one valve was not setting deep enough when closed it could have hammered out the rod bearing to where it rolled and locked up causing the rod to break and come out the side . Just something to look at . Adn like others have said always plasti gauge your bearings during your assembly .

It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
