Drill lubrication holes into the new bushing in correspondence with the existing lubrication holes on the connecting rod
small end.
Now ream out the bushing until the inside diameter (D) is 18.006 to 18.024 mm.
Crankshaft overhaul
The main bearing and big-end journals should not be scored or grooved.
The threads, tongue seats, and slots must be in good condition.
Check for fretting or burrs in the fillet between journal and shoulder.
Fillet radius: 1.5 mm.
With the aid of a micrometer, measure the ovality and taper of the big-end journals, taking the measurements in various
different directions (Sect. 3 - 1.1,
Cylinder/Piston).
Use a dial gauge to measure the alignment of the main journals by setting the crankshaft between two opposing centres
(Sect. 3 - 1.1,
Cylinder/Piston).
Unscrew all the plugs (4), (3) and (2) from the crankshaft; heating the crankshaft, if necessary, to remove the
threadlocker applied at the time of assembly.
