Power steering pump V-belt (VW Transporter T4)

The V-belt is tensioned correctly if it deflects approximately 5 mm when pressed with your thumb between the two belt pulleys. The V-belt is tensioned by adding or removing spacers between the two halves of the power steering pump V-belt pulley.

Replacement and tensioning

1. Using an Allen key, unscrew the 3 mounting bolts on the belt pulley while holding the belt pulley with a screwdriver (a) to prevent it from turning.

2. Remove the pulley head and V-belt.

3. Remember the position of the spacers inside and outside.

4. Put on the V-belt, install the pulley halves and spacers.

5. If the belt needs to be tightened further, remove 1 spacer washer between the pulley halves and install it on the outside.

6. Tighten the pulley halves to a torque of 20 Nm.

Caution! When tightening the screws, turn the belt pulley to avoid pinching the V-belt. Distribute excess spacers evenly behind and in front of the belt pulley.

7. Check the tension of the V-belt by pressing it with your thumb between the two pulleys. If the belt deflects by about 5 mm, it is tensioned correctly. If, for example, you need to tighten the V-belt more, remove one spacer washer between the pulley halves and install it behind or in front of the pulley.
