1. If not to specification use Tool No. FNH
00053 and press out the old bush using
the removal fixture as shown
in
Figure 34. Press fit a
new
bush through
the fixture using the installation detail and
into the connecting rod as shown in
Figure 34. After fitting a
new
bush ensure
all sharp edges and burrs are removed.
NOTE:
A,
Ensure the
split
in the small
end
bush
is
at
right angles to centre line
of
con-
necting rod.
B, Connecting rods
should
only
be
changed
as
matched
sets.
2.
Where
special tooling is not available for
the removal or fitment of the connecting
rod bush a standard bush can be fitted,
Figure 35, in the following manner:
3. Place the connecting rod securely
in
a
bench press. Manufacture from suitable
bar
stock, a press tool with the end face
ground
at
an angle to suit the connecting
rod bush side face. Position the tool on
the bush
and
gently drive the bush from
its position. It is recommended a guide is
manufactured to assist alignment
of
the
bar
stock
during this operation.
