remove rear seats and arm rest.
bow rear shelf and move forward. drive blind up until about 4 cm above shelf - cut power.
disconnect 4 pin plug on passenger side and take shelf out of car.
remove L-R end plugs on the moving top rail - small phillips driver.
remove 6 10 mm nuts holding aluminum rail/assembly to shelf.
move rail/assembly forward to release 3 clips. pull extended blind through the shelf to completely free rail/assembly. #
there are likely to be some flat spacers (washers) on some the six
bolts - make a note of where each goes -- some sticky tape would stop
them from falling off. disconnect motor plug from controller.
this shows the overview
with 3 mm allen key remove small countersunk bolt holding the circular plate to the gearbox.
use flat screwdriver to remove circular plate from driving peg of gearbox.
# note the orientation of the arms to the plate.
this may help
mark the positions of the 3 phillips bolts holding the motor-gearbox to the rail.
NOTE: if the motor-gearbox is not reinstalled in the same place then the top rail will not be horizontal!
remove the 3 phillips bolts. remove the three 4 mm torque bolts holding cover to gearbox.
remove cover of gearbox.
this shows the overview
while pushing down on the main gear, remove the fiber transfer gear. -- careful, the axle of this gear can fall out.
the main gear should jump anticlockwise about 10-15 degrees. while pushing down on the main gear, remove the end bolt from the end of the gearbox.
the main gear should jump anticlockwise about 120 degrees. lift out the main gear.
This shows the new steel gearwheel - top view
bottom view
turn the main gear over and remove the spring. put the spring into the new main gear making sure that the outer end of the spring engages on the stud
shown here
use a marking pen to indicate the region of full height gear teeth.
turn the new main gear over and replace in the gearbox after lightly greasing the teeth.
## the inner end of the spring must fit into the gap in the post of the gearbox -- can be difficult to get it in. while
pushing down on the main gear, use a crescent wrench on the driving peg
to turn the main gear clockwise about 140 degrees -- check the markings
to make sure that the full height gear teeth region is clear of the end
bolt. reinstall the end bolt and slowly release the pressure on the
wrench. -- the main gear should rotate anticlockwise until the full
height gear teeth region hits the bolt. insert the axle of the transfer gear into its socket in the gearbox.
install transfer gear onto axle and push until it mates with both the main gear and the worm gear on the motor.
reinstall gearbox cover -- it does not fit down completely just yet. install the end bolt at the end of the cover - should be fairly loose. with
small pickle fork or similar, push down on the transfer gear axle until
it enters its socket on gearbox cover -- can be difficult.
NOTE: push from the motor towards the axle of the main gear -- the photo shows a ring spanner but of course that must be removed.
if you're lucky the axle will slip in and you can squeeze the cover completely flat. reinstall the other bolts and tighten all of them.
remount the motor-gearbox onto the rail and hold loosely with one bolt. put rail/assembly back into the car and reconnect the 4 pin blind connector.
## drive the motor by switching "blind up" so that the driving peg rotates
about 15 degrees -- disconnect the motor connector to keep this
rotation. remount the circular plate onto the driving peg -- the blind should be extended by a few cm.
reinstall the countersunk bolt and the other bolts holding the motor to the rail
-- make sure that the motor is in original position. insert the blind through the shelf, reengage the three clips, and reinstall the 6 nuts
# you did remember to keep the spacer washers in the right places? reinstall the two end plugs on the top rail.
reconnect the motor to the controller. reconnect the 4 pin plug and check that the blind moves over its full range.
remount the shelf and reinstall the seats etc.
