Install the crankshaft (see Crankshaft Installation).
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/Twist Inspection
Measure the connecting rod bend.
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 blocks [C].
With the connecting rod held vertical, 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 de-
termine the amount of connecting rod bend.
If connecting rod bend exceeds the service limit, the con-
necting rod must be replaced.
