Determine big end bearing clearance
 P02 56
P02 57
The big end bearing clearance is given by
the difference between the internal diame-
ter of the big end bearing shell (a) and the
lifting journal diameter (b).
Calculation example
Desired: Big end bearing clearance
Given: -
Measured: Internal diameter big end bearing shell (a)
(a) =88.060 mm
Diameter lifting journal (b)
(b) = 88.000 mm
Calculation: Dimension (a) - Dimension (b)
88.060 mm - 88.000 mm
Result: =0.60mm

Aligning the con rod is not permissible.
Check con rod without bearing shells on
the con rod test device.
Permissible deviation (a) at a
distance of (x).
