After one side of the main bearing burned out, check the other side of the main bearing gap
January 10, 2019
The characteristics of the Lubricating Oil Lubricant Road of the S195 diesel engine (which is also the deficiency of the original design) is that the lubricant first passes through the main shaft of the flywheel and the journal, then passes through the crankshaft oil passage, and part of it flows from the crankshaft oil passage to the connecting rod bearing and the journal. The other part flows to the main bearing bush and the journal at the gear chamber, and finally flows from the gap of the main gear of the gear chamber to the lubricating gear and flows back to the oil pan. The oil pressure and flow rate of the lubricant oil obtained at the gear chamber end and the flywheel end are different. The main shaft of the gear chamber end is far away from the oil pump, the oil pressure is low, and the flow rate is small; at the same time, the oil leading to the gear housing end main shaft tile has to pass through two large leaks halfway, one is the flywheel and the other is the connecting rod bearing and shaft. Neck fit clearance leak. Therefore, once the gap of the main shaft of the engine flywheel is too large, a large amount of lubricant will leak there, and the main bearing bush leading to the gear chamber end will be burned due to insufficient lubricant. In the past, many drivers only saw the main shaft of the gear chamber was burned out, and only the main bearing bush on the side of the gear room was replaced. The main shaft of the gear housing was not replaced and burned again. It should be remembered that the S195 driving into the gear housing end of the diesel engin
