3 Screw threaded bolt (self-made) into crankshaft and counterlock with hex nut.
1   Hex nut M 12 x 1.5
2   Threaded bolt 10 mm dia
3   Hex nut M 10 x 1

 

4   Attach dial gauge holder with dial gauge to threaded bolt.
5   Position feeler pin at fitting point of centering surface. Set dial gauge to 0.

6 Rotate crankshaft for one full turn by means of tool combination. Vertical runout should not exceed max 0.10 mm.
Note: When rotating crankshaft, make sure that the feeler pin of the dial gauge is not getting stuck.

7   Correct vertical runout by light blows against intermediate flange.
8   Tighten fastening screws.
Note: If the vertical runout exceeds 0.10 mm, remove intermediate flange.
9   Increase diameter of both fitted bores in inter­mediate flange to 12.1 mm.
10    Repeat item 1-8.
