Crankshaft/Connecting Rod Cleaning
After r emoving 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
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 r od 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 a 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 connecting rod bend exceeds the service limit, the con-
necting rod must be replaced.

Service Limit: TIR 0.2/100 mm (0.008/3.94 in.)
Connecting Rod Twist
With the big-end arbor [A] still on the V block [C], hold the
connecting rod horizontally and measure the amount that
the arbor [B] varies from being parallel 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 connecting rod twist exceeds the service limit, the con-
necting rod must be replaced.
