• Can anyone help me with torquing specs for the 12pt. TTY crank nose bolt  on a 1.6 TD and 1.9AAZ TD? My Bentley is an old MkII issue, and doesn't even show the TTY 12 pt. bolt.

• 6 sided bolt w/ washer: 137ft lbs.
  Hex head bolt w/ washer: 111ft lbs.
  12 sided bolt w/ collar, no washer: 66ft lbs, 1/2 turn (180 degrees)

• Ok. So 111ft/lb for the old 12mm 6 point, 137ft/lb for the 14mm six point, and 66ft/lb +1/2 turn, even on the AAZ TD with the serp belt system?
   My Bentley doesn't show the 12mm, or the 12point, and it shows 130ft/lb for diesels, 148ft/lb for gassers.

• My manual doesn't cover the AAZ, so the values may be different for the AAZ. It covers up to the 1.6 NA and 1.6 Turbo motor.
