Measuring axial clearance of crankshaft

Risk of damage to bearing pedestals when the crankshaft is removed. If the bolts of the crankshaft bearing cap are loosened, the bearing pedestals of the cylinder block will be deformed, and damage to the bearings will result.

• Never remove the crankshaft.

Special tools and workshop equipment required

• Universal dial gauge holder - VW 387-

• Dial gauge - VAS 6079-

Procedure

• Screw dial gauge - VAS 6079- with universal dial gauge bracket - VW 387- to cylinder block as shown in the illustration.
• Position dial gauge against crank web.
• Press crankshaft against dial gauge by hand and set gauge to “0”.
• Push crankshaft away from dial gauge and read off measured value.

• Axial clearance: 0.066 to 0.233 mm
