Hot Metal

Published February 13, 2006

As mentioned in an earlier post, we needed to overhaul the engine in one of our tractors. After further investigation Dan, the assistant mechanic, discovered the reason why this tractor was not operating properly. Probably due to compression ring failure, pieces of the rings broke loose and were lodged along the side of the piston causing a portion of the piston to wear away. In addition to metal wear, combustion pressure was slipping by and entering the block cavity. This caused the oil in the crank case to be forced out under pressure. Dan has the situation in hand and is in the process of bringing this engine back up to specs. Good Job Dan!
