MAN Conrod bearing repair stage 3 = 0,75 mm sputtered 51024106518

About this part

Genuine MAN big-end bearing shells at the third repair stage, 0.75 mm undersize, for the D2840 LE301 and D2842 LE443. Shells at this stage are thicker to compensate for the journal diameter the crankshaft has been reduced to, and that is the whole mechanism: the bore in the rod is unchanged, so the material has to come from the shell. Anyone ordering shells for an engine of unknown rebuild history should assume nothing from the model number. Measure the journal, or read the stamping on the web, and order to that — a set of shells is inexpensive, but fitting the wrong stage produces either a seized bearing or a slack one, and both take the engine apart again. Both failures also look, from the outside, exactly like the lubrication problem the owner was trying to fix.

Supplied new, in the manufacturer’s packaging, with our warranty of up to 24 months.
