Check that each small end is lying square on the
hot plate. As the temperature guide, place a small
piece of
coreb
TiTtmans,
solder with a melting
pointing of about
250°C
on each small end (A).
Let them heat up until the solder melts. (Fig. 58)
PREPARING GUDGEON PINS
Check that each gudgeon pin rotates freely in its
piston.
Fit the gudgeon pins in turn to assembly
mandrel
ID).
\Do not tighten; the gudgeon
pin
must
be free to float between mandrel and guide.) (Fig. 59)
Fit
a thrust pad (C) (Fig. 60) which corresponds to
the gudgeon pin on the support base (A) and
clamp the piston to the support base with the clip:
the spotfacing on the piston must rest on the
thrust pad.
The following operations must be carried out
rapidly so that heat loss is reduced to a minimum.
As soon as the piece of solder melts:
Wipe off the solder droplet
Insert locating guide (D) in the piston
Fit the connecting rod to the piston
with
one
hand (extended flange (E) facing downwards)
Press
in
the piston
pin
quickly
with
other hand
until the guide bottoms against the support base.
After a few seconds, remove the connecting rod-
piston assembly from the support base; unscrew
the guide and remove the mandrel assembly.
Assemble the other two connecting rods in the
same way.
Mark the three assemblies made up in this way so
that they are immediately identifiable with the LH
bank of cylinders. (Fig. 67)
Connecting rod-piston assemblies: RH cylinder
bank.
Spread the small ends on connecting rods 4-5-6
evenly round the hot plate, with extended flange
face downwards. Then
carp/
out the assembly
operations as indicated earlier, taking care to
insert the gudgeons pins with
extendea
flange (E)
facing upwards.
Mark the three assemblies
maae
up in
this
way so
that they are immediately
identifiaole
with RH
bank cylinders. (Fig. 67)
