Engines
The engine D 0826 LE is in-line vertical liquid-cooled 6-cylinder four-stroke Diesel engine
with direct injection, turbocharger and intercooler.
Engine block
The cylinder block is a single piece of alloy cast iron. To increase its stiffness, it is ex-
tended to a level below the crankshaft centre line. The engine has replaceable dry cylin-
der liners and cylinder heads with shrunk-in valve seat rings and replaceable valve
guides. For every two cylinders there is one cylinder head of high-alloy cast iron.
Piston / Conrod / Crank assembly
The integral die-forged crankshaft is carried in seven bearings. Balance of masses is by
integral balance weights.
Sealing of the crankshaft penetration is by radial seals in the flywheel housing and the
timing gear cover.
The connecting rods are horizontally split and can be removed upwards together with the
piston.
Connecting rods and crankshaft run in ready-to-fit thin-walled steel-backed plain bear-
ings with lead bronze lining and a ternary running layer.
The combustion chamber is integrally cast in the crown of the aluminium alloy piston
