Hello and welcome to the forum :)

It sounds like the rubber bonding has perished and the outer part of the pulley has broken away.

What engine is in the car? I'm not familiar with the pre 1999 engines.

If your Scenic is the MK1 Phase 2 Scenic? from 1999 on then it will have the 2.0 16 valve F4R.

To remove the inner part of the auxilliary belt pulley you will need to undo the crank shaft pulley bolt. The crank shaft timing belt sprocket is behind the auxilliary belt pulley and retains it in place as the sprocket isn't keyed you will need to have a TDC setting pin and a cam shaft locking tool to set the engine timing correctly.

What age is the car?

I use an air impact wrench or remove the TDC sensor if its the F4R engine and get some one to jam a large flat blade screw driver in the starter motor ring gear.

DONT TURN THE ENGINE OVER
with the crank shaft pulley bolt loosened if it's an 2.0 F4R the timing will be lost and you will bend the valves!:eek: and you can't just do the bolt back up again and hope the engine timing will okay.

In which case yours will be a Mk1 Phase 1 Scenic and therfore the engine should be the 2.0 8v F3R. This thread will be of interest

So unlike the F4R 2.0 the F3R crank shaft pulley will have a woodruf key? So you should be able to undo the crank shaft pulley bolt without loosing the engine timing? I don't have any experience of the F3R engine so hopefully another memeber can confirm
