Host crankcase, routinely checked once a month

Today our ship was in the port of Kaohsiung and carried out a routine inspection of the main engine crankcase, which was a routine inspection once a month. Open the crankcase door, first visually check to see if there are any foreign objects inside, especially whether there are white alloy chips, in fact, it is generally climbed into the crankcase to check one cylinder at a time. If there are alloy chips, you should pay special attention, it may be that the main bearing or crosshead bearing or crank pin bearing is damaged, the bearing inner wall alloy is falling off, and such a thing has been sent before.

In addition, because other companies have appeared in other companies before, the cross head screws are not locked after the overhaul of the main engine crane cylinder, resulting in the crankshaft being broken. So when checking the crankcase, check whether the cross head screw is loose, this screw will generally be marked before removal, and the mark after locking should be the same as before disassembly. At the same time, you need to check and clean the RAIN filter of the host oil lubrication self-flushing filter to see if there are any metal chips inside, in fact, the filter before the host oil separator gives the oil pump is best to check it.
