1
Measure the width (A) of the main (adjustment) neck and note the value obtained.
The measurements mentioned in the table should be maintained.
2
Measure the adjusting bearing cover (B) (between the thrust washers' contact surfaces).
3
Obtain the thickness of the compensating washers as follows: :
Primary (adjustment) neck width. - Bearing cover width (B). - Crankshaft end play (average value). = Value obtained: 2 results in the thickness of a washer.
