Deflection Pulley ????? Help

[Pinhead]

This evening, the bearing on my "Deflection Pulley" decided it'd had enough on the M25 at about 4:30pm. Called the AA out and was finally towed home at 8:45pm.

I've ordered one and it'll be here Thursday....... But now I have to fit it, it would happen in the freezing cold. But that's life.

It'll probably be a ballache of a job, not least working out where the drive belt goes around all the pulleys😒.The inner bearing race is still on the engine.

So if anyone can give me any pointers on fitting one it'd be a big help.

My car is a A4 2.L TDI. Avant S Line.

Thanks to All
