9-22 CRANKSHAFT/TRANSMISSION
Crankshaft and Connecting Rods
First, tighten the nuts with 12.8 N·m (1.3 kgf·m, 113 in·lb)
of torque.
Next, tighten the nuts 175°.
Using a torque angle gauge [A], tighten the nuts specified
angle.

Crankshaft/Connecting Rod Cleaning

After removing the connecting rods from the crankshaft,
clean them with a high flash-point solvent.
Blow the crankshaft oil passages with compressed air to
remove any foreign particles or residue that may have
accumulated in the passages.

Connecting Rod Bend Inspection

Remove the connecting rod big end bearing inserts, and
reinstall the connecting rod big end cap.
Select an arbor [A] of the same diameter as the connect-
ing rod big end, and insert the arbor through the connect-
ing rod big end.
Select an arbor of the same diameter as the piston pin
and at least 100 mm (3.94 in.) long, and insert the arbor
[B] through the connecting rod small end.
On a surface plate, set the big-end arbor on V block [C].
With the connecting rod held vertically, use a height
gauge to measure the difference in the height of the
arbor above the surface plate over a 100 mm (3.94 in.)
length to determine the amount of connecting rod bend.
If the connecting rod bend exceeds the service limit, the
connecting rod must be replaced.
Connecting Rod Bend
Service Limit: TIR 0.2/100 mm (0.008/3.94 in.)

Connecting Rod Twist Inspection

With the big-end arbor [A] still on V block [C], hold the
connecting rod horizontally and measure the amount that
the arbor [B] varies from being paralleled with the surface
plate over a 100 mm (3.94 in.) length of the arbor to de-
termine the amount of connecting rod twist.
If the connecting rod twist exceeds the service limit, the
connecting rod must be replaced.
