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.
