About this part
Genuine MAN injection pump plunger for the D2866 LE401. The plunger and its barrel are a matched pair, lapped together to a clearance measured in microns — that clearance is what generates injection pressure, and there is no seal between them beyond the fit itself. A plunger is therefore never a generic spare: it belongs with its barrel, and ordering one without knowing how the pump is to be rebuilt invites disappointment.
Supplied new, in the manufacturer’s packaging, with our warranty of up to 24 months.
