2.2

Pre-drilling: Do not use cooling oil or drilling fluid as this might contaminate theoil sample.

Pre-drill both centre punched locations using a 4 mm drill.

2.3

Reboring to 9 mm:

Use a 9 mm drill to rebore the 4 mm bore hole. The second 4 mm bore hole is only used toventilate and speed-up the silicone oil sampling and therefore does not need to be rebored!

2.4

Thread cutting:
