CAUTION!
DO NOT have the cylinder block mounted to the assembly stand
while measuring the cylinder bores (Repair Group 13). The cylinder
block is deformed by its own weight under these conditions and
such stress will result in false measurements that are not accurate
after the tension has been relieved. - Mount engine to stand using holding fixture VW 540 along with VW
