Lombardini
Lombardini makes the engine inside the dumper, genset or mini plant, and it is listed by engine model rather than by the machine around it: the 102 LDW, the 11LD535, 625 and 626, the 12LD435 and 475, and the 5LD675 and 825 series. Starter motors and alternators are matched to the engine model in the Machinery Parts Finder on PartsForMachines, with the price on every listing. Kohler owns Lombardini, and a Kohler-badged engine is listed under the same Lombardini code.
Lombardini engine starters and alternators: 102 LDW, 11LD625, 12LD475, 5LD825
Starter motors and alternators are listed against the Lombardini engine model with OE number and voltage on the listing, the LD air-cooled singles and twins and the LDW water-cooled units alike.
Read the engine model off the block plate. The Machinery Parts Finder is the route: Lombardini, the engine model from the dropdown, then starter or alternator. A Lombardini or Kohler number goes into the header search. Plate worn, photo of the block to 07754288583 on WhatsApp. The Compatible tab confirms.
Air-cooled engines are oil-critical, so oil to the Lombardini grade through the Oil Finder and filters head the wider range, then batteries and the rest by specification. Engine model not in the Finder? Ask Simon.
