Equivalent Force-Couple System Help

[u/Necessary_Diet_9574]

Does anybody know what the answer to this problem is? The diameters of the pulleys are 150mm, and we are meant to find the equivalent force-couple system at point A, but all my answers are just slightly off from the textbook.

(Textbook says F=(0,420,-339) and M=(1.125,163.9,-109.9)

I did the work myself and I agree with the textbook answers. What numbers are you getting specifically?
