The winch is installed ........ and it works !!
The special N4 mounting plate for the Daily is designed for 12,000 lbs (5.4 t) winches. I had to modify it somewhat to fit a winch of 15,000 lbs (6.8 t): grinding the longitudinal edges because the winch is approx. 5
mm too wide, widening from 11 to 13 mm of the 4 fixing holes and
drilling of 4 additional holes because the winch should be fixed by 8
screws class 8.8 (I chose to use 8 x 12.9 for security).
Indeed,
although most of the Dailys that I could see so far are equipped with a
5.4 t winch, I decided to get closer to the golden rule that says to
choose the strength of the winch equals at 1.5 x the weight of the vehicle. That is 1.5 x 5.5 t = 8.2 t.
6.8 t is still far enough from this ideal but more acceptable than 5.4 t and remains affordable.
I did not choose the top but a good value for money: a Comeup winch 15 DV (12 V / 15 000 lbs).
We hope not to have to use it. A little naive hope because the bogs in the African rainforest are pre-programmed.
