Drive Belt: Service and Repair

REMOVAL
1. Raise the car and remove the right front wheel.
2. Remove the front section of the fender liner and lower the car.








3. Slacken the belt by applying a hard pull upwards. Fix the belt tensioner in the compressed position by means of locking pin 83 94 488, or equivalent.





4. Raise the car. Remove the tensioner idler-wheel pulley and the belt.





5. Remove the locking pin (e.g. use a pair of water-pump pliers or a large screwdriver). Watch your fingers!








6. Remove the top fixing bolt for the belt tensioner and swivel the tensioner down. Remove the two fixing bolts in the mounting plate and lift off the plate complete with tensioner.

INSTALL
1. Install the bolts in the mounting plate, swivel the tensioner down and install the top bolt.

NOTE: As the tensioner is compressed, oil is forced through a tiny gap between the plunger and the cylinder wall, and it therefore takes time for the oil to flow from one chamber to the next. With this in mind, push the tensioner in slowly when tightening the belt.








2. Using a ratchet handle, advance the tensioner and then fix it in position by means of locking pin 83 94 488, or equivalent.





3. Install the belt and the idler-wheel pulley. Make sure that the belt is correctly seated round all the pulleys and then lower the car. Apply a hard upward pull to the belt to release the pressure of the tensioner, and remove the locking pin. Raise the car.
4. Install the fender liner.
5. Install the wheel and tighten the bolts to 130 Nm (96 ft. lbs.). Lower the car.
