• connecting rod nuts
▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼
• Tighten the connecting rod nuts in the
following way.
NOTE:
• How much the connecting rod nut is
tightened depends on how much the
connecting rod bolt stretches.
• Use a general micrometer
1
to mea-
sure the connecting rod bolts.
a. Before tightening the connecting rod
nut, measure the length of the con-
necting rod bolt with an accuracy of
three decimal places.
b. First tighten the connecting rod nut to
20 Nm (2.0 m • kg, 14 ft • lb), then up
to 40 Nm (4.0 m • kg, 29 ft • lb).
c. Measure the length of the connecting
rod bolt after tightening the connect-
ing rod nut and then calculate how
much the bolt has stretched.
d. Further tighten the connecting rod
nut until the connecting rod bolt has
stretched by between 0.170 and
0.175 mm.
ACHTUNG:
CAUTION:
If the connecting rod nut cannot eventu-
ally be tightened to about 50 Nm (5.0 m
• kg, 36 ft • lb), too much MOLYKOTE
®
‚
“G-n” paste may have been applied.
Loosen the connecting rod nut and
check the loosening torque. If the loos-
ening torque is less than 40 Nm (4.0 m •
kg, 29 ft • lb), too much MOLYKOTE
®
‚
“G-n” paste was applied. In that case,
replace the connecting rod bolt with a
new one and apply a thin uniform layer
of MOLYKOTE
®
‚ “G-n” paste to the
threads of the connecting rod bolt, the
contact area between the connecting
rod and the connecting rod bolt, and the
seat of the connnecting rod nut. Then,
tighten the connecting rod nut as
explained above.
WARNING
WARNING
Always replace the connecting rod bolt
with a new one if loosening the con-
necting rod nut after it was tightened.
Never use a connecting rod bolt more
than once.
