Hi, if it is assembled like the old Alpine then its quite straight forward
with the spindle in the raised position you need to remove the coiled tensioner spring
next remove the 3 handles and gently pull out the splined shaft
once this is out you can now -by hand- lower the main shaft out as a unit
once out there will be a couple of circlips to be removed and then the inner shaft can be removed
you now have access to all of the main components – had to do this to my Alpine to change the Taper roller bearings the other month
cheers
