As i havent seen this here i thought it might help some one if they want to do a full rebuild.
firstly remove your steering column how ever you wish to do it.
next undo the 2 screws on the bottom bracket and remove and remove the clip at the bottom also.
at this point the bottom bearing etc can be removed,
now undo the 3 screws that hold the indicator assemble in and remove that.
undo the 4 bolts to the steering column mounting bracket and remove.
undo the 2 screw to the columns plastic cover and slide it back alittle.
undo the 2 screw that hold the ignition switch on, to remove this rotate the switch 90dg and take it away from the rod.
no photo, sorry.
take off the C clip, washers and spring from the shaft in the coffee pot.
undo the 4 screw the hold the coffee pot on and remove.
now take off the plastic cover
the steering shaft should be able to be taking out now also.
at this point you should have everything apart. i done the mods for the lower bearing as described in another thread here.
now for the ignition switch rebuild,
bend back the 3 bits that hold the switch together.
be careful opening it, there a 2 small ball bearings that u dont want to lose.
clean up all parts scotch bright the copper contacts in it and apply some die electric grease and reinstall all bits as they were.
