Special tools

- Internal dial gauge 75 to 100 mm (2.95 to 3.95 in.)

Measure bore at 3 locations in both directions -A- across the engine and -B- in line with crankshaft.

- Deviation from nominal dimension max. 0.08 mm

Note:

- DO NOT measure the cylinder bores when the engine block is mounted on a repair stand using the VW 540 adapter bracket or inaccurate measurements will result due to the uneven bending of the engine block on the repair stand.
