Re: XB GTs
Power steering is a Bendix-bishop VARIABLE ratio. "Vaiable ratio" refers to the fact that steering in the straight ahead position is substantially less direct then in turns.
maximum (on centre): 17.5:1
minimum (on lock):11:1
Only 2 1/2 turns lock to lock required. This feature is provided by a variable pitch hourglass worm. Another great aussie innovation.
hope the link works.
