MAN Conrod bearing repair stage 1 = 0,25 mm sputtered 51024106516

About this part

Genuine MAN big-end bearing shells at the first repair stage, 0.25 mm undersize, for the D2840 LE301 and D2842 LE443. First-stage shells are the ones most often needed, because a crankshaft that has been reclaimed once is usually taken to the first standard undersize rather than further — the grinder removes the minimum needed to restore a true, round surface. Ordering the right stage depends on knowing what was done to the shaft, which is why reputable machine shops stamp the undersize onto the crankshaft web when they grind it. Where a shaft carries no such marking and its history is unknown, the journals have to be measured before shells are ordered , and not after. Confirm the figure against the shaft in front of you, since a machine shop's stamping is evidence of what was done and the paperwork sometimes is not.

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