4. Mark the belt direction with chalk so
it can be replaced the same way, then
using the 5/8” open-end or adjustable
spanner, rotate the square tab on the
top of the belt tensioner towards the
front of the car to release the belt
tension.
5. Slide the 5mm hex key (or other
suitable metal shaft) into the pin to
lock the tensioner in the open
position, then remove the belt.
6. Loosen the 6 crank pulley bolts
in a diagonal pattern. To stop the
crank pulley from rotating whilst
loosening the bolts, use a 19mm
ring spanner or socket on the
centre crank bolt to hold it
steady.
On 2006-2007.5 models the
crank pulley bolts are 6mm hex
socket heads and are stretch-
type bolts. Make sure to use a
good quality 6mm hex key, one that has no wear on the points or you may round the bolt
sockets. Take care when undoing these bolts, as they can be quite tight and can be easy to
round. If the bolt shows signs of starting to round before you can loosen it, try a product that
freezes the bolt to help loosen it.
On 2007.5-2008.5 models with triple square socket bolts, make sure to use the correct driver as
described at the beginning on these instructions.
7. Remove the crank pulley bolts and
crank pulley, then install the GFB
pulley on the crankshaft, making sure
to align the locating pin with the
matching pocket on the backside of
the pulley. The GFB pulley should be
a neat fit on the crankshaft – if it will
not press or wiggle on by hand, do
NOT lever or hammer it on! Check
for rust or burrs on the crankshaft
and remove as necessary.
