The main bearing and big end journals should not be scored or grooved; the threads, keyways, and slots must be
in good condition.

Use a micrometer to measure oval and taper of the crank pin. Measure oval and taper in several different
directions.
Use a dial gauge to measure the alignment of the main journals by positioning the crankshaft between two
centres.
Oval 0.005 mm.
Taper 0.005 mm.
Main journals alignment Ø 0.01 mm.
Loosen all crankshaft plugs (4) and (5), heating the crankshaft, if necessary, to remove the sealant applied at the
