V-belt for alternator or alternator and water pump (VW Transporter T4)

Please note: Depending on the equipment and for easier access, it may sometimes be necessary to tilt the radiator forward (see subsection 2.2).

Replacement and tensioning

1. Loosen the mounting screws (1) of the tension bar (A) and the generator by approximately one turn (B – tension nut).

Attention! The generator must be easily movable. This means that it must be able to swing to the side under its own weight.

2. Turn the tension nut (B) to the left, loosening and removing the V-belt.

3. Put on the V-belt.

4. Turn the tension nut to the right and tension the V-belt. The belt is tensioned correctly if the old belt is tensioned with a torque of 4 N·m applied to the tension nut, for the new belt - 8 N·m. Holding the nut in this position, tighten the fastening screw 1 with a torque of 35 N·m.

Note! A torque wrench with a 22 mm open-end socket is required to tighten the tension nut. You can also use the open-end socket HAZET 2593-22 in combination with a torque wrench and a 13 mm strongly offset open-end socket.

5. Tighten the mounting bolts "Generator on support" to a torque of 35 N·m, and "Tension eye on cylinder head" to a torque of 20 N·m.
