MAN Flywheel 51023017379

About this part

Genuine MAN flywheel for the D2866 LE401. Damage to a flywheel is worth diagnosing before ordering, because several distinct faults present similarly. Chipped ring teeth cause starting trouble; a distorted or heat-checked friction or coupling face causes vibration; a crack radiating from a bolt hole — rare but serious — condemns the component outright. Only the first of those is repairable by changing the ring alone. Inspect all three areas with the flywheel off and clean, under good light, rather than deciding on the basis of the symptom that prompted the work, since more than one condition is often present on a flywheel that has run for decades. Cracks in particular are found by looking for them rather than by noticing them, and a flywheel that has done thirty years deserves the search.

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