NOTE: If timing belt is excessively noisy between idle and 2000 rpm a modified timing belt, tensioner pulley and guide pulleys should be fitted. Refer to a Renault dealer.
WARNING: Engines with variable valve timing: Mark camshaft sprockets and camshaft adjusters with chalk or paint prior to timing belt removal to assist alignment on installation.

yes all this info is in my timing belt Auto Data book I am myself a car mechanic, but what I needed to know, was how I could gain access to the ring gear, I had looked all round the gear box but could not see any access points, but as the wife needed the car back I had my mate to trailer it to Renault, I'l just have to bite the bulet and let them sort it. But thank you for trying to help, Cheers Customer.
