Iveco N60 ENT M37, Technical And Repair Manual, Page: 13 / 194

The crankshaft is made in steel hardened by induction and
rests on seven mountings; inside the hollow shaft are the
ducts for the lubrication oil circulation.
On the front tang, the oil pump driving gear, the phonic
wheel, the flywheel connecting hub and the driving pulley of
the ancillary components are keyed on.
On the rear tang the camshaft driving gear and the coupling
flange to the engine flywheel are keyed on.
The bench half bearing are in cast babbitt lining steel and the
6
th is fitted with a shoulder ring to contain the end play of
the driving shaft.
Details 1 and 2 in figure,assembled by negative allowance on
the rear tang are not replaceable. The front and rear retain-
ing rings are slide type with radial seal and require special fix-
tures to assemble and disassemble them.
Connecting Rods
They are made in steel, manufactured by pressing with small
end oblique edged and cap separation obtained by fracture
splitting technique.
The connecting rod half bearings are cast babbitt lining steel.
Every connecting rod is marked on the body and on the cap
by a number that identifies their coupling and the cylinder
into where has to be assembled; moreover onto the body a
letter has been impressed stating its weight class.
In the case a replacement is necessary, only one type of con-
necting rod is available as spare part of an intermediate class
weight that can be used to replace anyone else. The con-
necting rods still efficient therefore, do not need to be
replaced even if they are of a different class weight.
