. Use compressed air
to eliminate any residues.
Replace and assemble the conical cap in hole B (B1 if present - tightening torque at 30 Nm) and caps in
holes D, after having performed cleaning operations.
Position crankcase
G
onto a workbench.
With a dial gauge, measure the diameter in correspondence to points
J-M-N (Fig. 8.2)
lengthwise and
diagonally with regard to axis
H
of the crankshaft.
If ovalisation or wear detected in a single point in
J-M-N
is greater than +0.05 mm with regard to the value
in
Tab. 8.1a
, you are required to perform grinding operations on all cylinders F.
Refer to
Tab. 8.1a
to establish the clearance value of cylinders subjected to grinding operations.
Important
•
The grinding involved is of +0.20.
•
Cylinder grinding operations must observe KOHLER SPECIFICATIONS - cod. ED0035612500.
•
Grinding must be strictly performed on all cylinders F.
•
Tab. 8.1a details the dimensional values of new components only.

The increase of +0.20mm, may already be present on the engine.
•
If the increase of +0.20 mm is already present, no further adjustments can be made. *
