How many rigid links have you created, and what geometry is each one attached to?
Rigid links are exactly that - rigid - so they will transfer all the load between surfaces they connect, and if they 'bridge' a component then that component will not deflect at all - hence will see no load.
You could use contacts, or you could use a pair of Weighted Links plus a spring for each pair of surfaces. The key question is which parts of the assembly are you looking to analyse? Are you interested in bush surface pressure, or component stresses away from the holes? If the latter, I wouldn't even include the bushes in the model...
