Isuzu
Isuzu makes the engine inside the machine, and the N-series trucks that carry it, so everything here runs on the engine code from the block plate: 4LE1, 4LE2, 4BG1, 4BG1T, 6BG1 and 6BG1T. Starter motors, alternators, radiators and turbochargers are matched to the code in the Machinery Parts Finder on PartsForMachines, with the price on every listing. The excavator, genset or truck around the engine makes no difference. Isuzu pickups and cars are a different catalogue.
Isuzu engine starters, radiators and turbos: 4LE1, 4LE2, 4BG1, 6BG1, NPR
Starter motors and alternators are listed against the Isuzu code with OE number and voltage on the listing, radiators for the N-series trucks and the larger engines alongside, and turbochargers for the T-suffix engines. The 4LE and 4BG codes sit inside a good deal of Hitachi, JCB and Kobelco plant, which is why they are listed here by engine rather than by machine.
Read the code off the block plate. The Machinery Parts Finder is the route: Isuzu, the engine code from the dropdown, then starter, alternator, radiator or turbocharger. An Isuzu or supplier number goes straight into the header search. Plate unreadable, photo of the block to 07754288583 on WhatsApp. The Compatible tab lists every machine the engine sits in.
Oil to the Isuzu grade through the Oil Finder and filters by size head the wider range, then batteries and the rest by specification. Engine code not in the Finder? Ask Simon.
