The distance between the indicator studs on the 
tool illustrated here is 75 mm. The distance 
between one of the indicator studs and the 
measuring surface must be max. 0.05 mm when 
measured using this tool. Check with a feeler 
gauge.

Check also whether the connecting rod is bent in 
an S-shape. This is done by measuring the 
distance between the outside of the connecting 
rod bushing and the level surface of the tool. 
Turn the connecting rod around and measure the 
corresponding distance. The difference between 
the two measurements should be between 
3.3-4.5 mm.
