I replaced mine without any issues.
I only removed one idler puller, the one with the with the flange towards the front of the engine. Putting the belt back on is a bit tight just make sure the tensioner is fully released, a third hand helps I used a spanner and tied it off to a convenient point on the car.
You don't want to be undoing the pinion shaft bolt this is Locitited on as there have been a number of failures of these working loose.
This link has instructions for replacing camshafts and includes instructions for cam belt replacement.
