6. Counterhold crankshaft with ring spanner (A), pull spur gear off crankshaft journal by screwing spindle in using ring spanner (B) or ratchet. [Note: Check temperature when heating the new drive pulley using temperature gaugeVAS 6519, or hand-held multimeterV.A.G 1526D in combination with temperature sensorV.A.G 1526D/1. To do this, push measuring tip of temperature sensor onto drive pulley.At a temperature of 200 °C there are approx. 4 seconds remaining to position the drive pulley onto crankshaft.There is more time for positioning at a higher temperature (220 °C = approx. 6 seconds).Ensure absolute cleanliness on crankshaft end.]
7. ⚠ The maximum temperature of 240 °C must not be exceeded, because this will lead to discolouring and distortion of the drive pulley. — Place new spur gear onto a commercially available hot plate and heat to at least 200 °C, maximum 240 °C. The inscription faces upwards.
