About 5120251210 - Bearing

5120251210 is a bearing catalogued for MTU 1163 engines. It is the later number for 5120250910, so lists quoting that number are normally supplied as 5120251210. The catalog unit weight is 1.080 kg, which we use to estimate freight before quoting.
Technical Notes: Bearings
Main and connecting-rod bearings support the crankshaft and run on a thin oil film. MTU bearings are supplied in size grades to suit original and reground crankshafts, so the size marked on the old shells or on the crankshaft record has to be known before ordering.
When This Type of Part Is Usually Replaced
- the engine reaches its major-overhaul interval
- oil analysis or filter inspection shows bearing material
- oil pressure loss or knocking points to bearing wear
Checks Before Ordering
- Confirm the size grade (for example size 0 or an undersize) from the old shells or crankshaft measurements
- Replace bearings as complete sets per crankshaft journal type
- Thrust bearings and washers should be checked together with the main bearings
