
The MAX allowed value of wear for B1 and B2 is
0.120 mm.

To grind the crankshaft, a decrease in diameter of the
halfbearings and connecting rod is provided for at 0.25
mm and 0.50 mm, to grind gudgeon pins A1 and B1 ,
measure the values of diameters A2 and B2 by
assembling the decreased half-bearings, define the
diameter to grind of pins A1 and B1 ,
observing the clearance indicated in Tab. 8.5.

.
Using a dial gauge, measure the axial shift of crankshaft
E
.
Axial shift must be a
MIN
of 0.18 mm and
MAX
0.38 mm..
