Inspection
Camber of the crankshaft
The camber of the crankshaft must be less than 0.08 mm
(.0031 in.).
The camber of the crankshaft can also be measured at each
end using a dial indicator.
First, measure the camber while the crankshaft is installed in
the engine. If the camber exceeds the prescribed tolerance, it
may be because of a worn bearing or a warped crankshaft.
Remove the bearings and measure the camber once more on
V-blocks at distance "A" as indicated in the following
illustration.

NOTICE:
It is not possible to get an accurate measure of the camber of
the crankshaft between the tailstock centres of a lathe.
If the camber exceeds the prescribed tolerance, repair or
replace the crankshaft.

Using a thickness gauge, measure the distance which
separates the stop washer from the counterweight of the
crankshaft. If the distance exceeds the prescribed limits,
replace the crankshaft or have it repaired.
