Shaft
The 6105 and 6125 engines include a cam in head,
actuating four valves per cylinder and an electronic
unit injector (EUI) fuel system. They are vertical stroke,
in-line, valve-in-head, 6-cylinder diesel engines. The
firing order is 1-5-3-6-2-4.
The cast block has ribbed walls to add strength and
rigidity, and to decrease noise and vibration. The 6105
and 6125 use the same block. The crankshafts and
pistons are different to produce a long stroke and short
stroke engine.
