inspection and reconditioning procedures of main bearing

2020-3-18It is important to determine inspection procedures and establish regular inspection intervals based on the importance of the system or machine 3 Inspection When Machine is Running 3 1 Bearing Temperature Bearing temperature generally rises with start-up and stabilizes at a temperature slightly lower than at start-up (normally 10 to 2020-8-18Main bearing temperature [C] Fuel viscosity [cSt] Fuel flow to engine [m/h] or [l/min] 7 4 Reconditioning of connecting rods by SECO During the standard inspection or after changing the main- and/or big end bearings it has to be checked if there are any micro-cracks at the edges between the cranks the shaft and conrod pin

General Bearing Handling And Inspection

2020-8-18The inspection area must be clean and free from dirt and debris to avoid contaminating the bearing Even a small piece of debris that enters a bearing can create a point of high stress that could lead to spalling and early fatigue In addition to examining the bearing a full inspection should include the housing and shaft
