Engine
Crankshaft
The main bearing and big-end journals should not be scored or grooved;
the threads, keyways, and slots must be in good condition.
Check for fretting or burrs in the fillet between journal and shoulder.
Fillet radius: 2 mm.
With the aid of a micrometer, measure the ovality and taper of the big-end journals, taking the measurements in various different
directions.
Use a dial gauge to measure the alignment of the main journals by setting the crankshaft between two opposing centres.
At each overhaul it is strongly recommended to clean the crankshaft's internal oilways.
The prescribed values are given in Sect. C 1.1.
The crankshaft is supplied in two size classes (journals) A and B, as punch marked on the side of the crank web on the pinion side.
