Cylinder Block Assembly: Testing and Inspection

Checking cylinder bores
Special tools, testers and auxiliary items required
- Internal dial gauge 50 ... 100 mm

Work sequence





- Take measurements at 3 positions in both lateral - A - and longitudinal - B - directions, as illustrated.
Difference between actual and nominal diameter not more than 0.10 mm.

Note: Measuring the cylinder bores must not be done when the cylinder block is mounted on a repair stand with engine bracket VW540 as the resulting measurements would likely be incorrect.
