The same block is published at 147 kW plain, 165 to 175 kW turbocharged and 213 to 228 kW intercooled, so the machine build fixes the rating.
Injection is by a mechanically governed in-line pump, while several market entries describe the same engine as common rail, which sends buyers to the wrong pump and nozzle numbers.
1-13650059-0 and 1-13610944-0 both circulate in listings for this engine across the EX300 family.
One market entry headed with this engine quotes 15.7 litres and a 147 mm by 154 mm bore and stroke, figures that belong to a larger engine.
The EX300-5 figure is measured at 1900 rpm, not the 2000 rpm figure published for the engine alone.
Units appear from 1000 to 6462 per piece, most between 2000 and 4000, alongside one set printed at 39108.
Liner set 1-87810908-0; cylinder head 1-11110846-4; rocker arm 1-12610-045-2; oil pump 1-13100191-1; water pump 1-13650059-0; crankshaft 1-12310503-2; nozzle 1153002896; turbocharger 114400-3140; in-line pump; overhaul kit.
The EX300, EX300-2, EX300-3, EX300-3C and EX300-5, with the EX350K also listed. Outside that family it is listed for Sumitomo in the SH300 and SH450-3.
The family is published in three forms: plain near 147 kW, turbocharged from 165 kW and intercooled between 213 and 228 kW, with torque rising across them.
Mechanically. It uses an in-line pump with a mechanical governor and a boost compensator, so there is no common rail or control module to match, and the pump and nozzle numbers come from the build plate.
Liner set 1-87810908-0 is supplied with matched pistons and three rings, and dry liner protrusion must land between 0.05 and 0.10 mm above the deck.
Only against the plate, since one block covers plain, turbocharged and intercooled builds across those machines.
The engine model and serial from the plate, the machine model with its serial, and photographs of both.
