A = Selection class Ø 135.000 to 135.012 mm
B = Selection class Ø 135.011 to 135.023 mm
X = Selection class marking area
On finding maximum wear greater than 0.150 mm or
maximum ovalization of 0.100 mm compared to the values
shown in the figure, you need to replace the cylinder liner as
no grinding, facing or reconditioning is permitted.
REPAIR OPERATIONS
CYLINDER BLOCK
Checks and measurements
Internal diameter of the cylinder liners is checked for
ovalization, taper and wear, using a bore dial (1) centesimal
gauge (2) previously reset to ring gauge (3), diameter 135
mm.
If a 135 mm ring gauge is not available use a
micrometer caliper.
A = Ø 153.500 to 153.525 mm
B = Ø 152.000 to 152.025 mm
C = Ø 153.461 to 153.486 mm
D = Ø 151.890 to 151.915 mm
The diagram shown in the figure gives the outside diameter
of the cylinder liner and inside diameter of its seat.
The cylinder liners can, if necessary, be extracted and fitted
several times in different seats.

The measurements have to be made on each single cylinder
liner at three different heights and on two levels (A-B) at right
angles to each other as shown in Figure 7.
(Demonstration)
The cylinder liners are supplied as spare parts with
selection class ”A”.

Position the parts 99360706 (2) and the plate 99360728 (4)
as shown in the figure, checking that the plate (4) rests on the
cylinder liner correctly.
Screw down the nut of screw (1) and extract the cylinder
liner (3) from the crankcase.
Always replace the water seals (3, 4 and 5).
Fit the adjustment ring (1) on the cylinder liner (2). Lubricate
the bottom of it and mount it in the cylinder assembly using
the appropriate tool.
Check the protrusion of the cylinder liners with tool 99360334
(2) and tightening the screw (1) to a torque of 225 Nm.
Using the dial gauge 99395603 supplied as standard with the
dial gauge base 99370415 (3), check that the protrusion of
the cylinder liner over the supporting face of the cylinder
head is 0.045 - 0.075 mm (Figure 16); if this is not so, replace
the adjustment ring (1) (Figure 14), supplied as a spare part
with several thicknesses.
On completing assembly, lock the cylinder liners (1) to the
crankcase (2) with the pins 99360703 (3).
