Upper crankshaft main bearing shell / LS MT3.35 / LS MT3.40 / LS MT3.50 / LS MT3.60 / EGQ110 / 40352933

Upper crankshaft main bearing shell for LS Tractor tractors, LS MT3.35, LS MT3.40, LS MT3.50, LS MT3.60 series and others.

Main bearing shells of the engine are half-round rings that are fitted in special seats in the engine block, between the crankshaft (main shaft) and the engine block (this applies to the centre shaft journals), in order to eliminate the clearances that arise during engine operation. Main bearing shells support the shaft and guarantee its correct position relative to the engine block, so that the power produced is transmitted as smoothly as possible. The first signs of bearing shell wear are a rattling noise when starting the engine.
