Idler Pulley clearance to remove and replace

I tried to lever the engine away but have ended up with a leak on the power steering coupling pictured below. As far as I can tell the inner 12mm threaded bolt has not unspun, but I am on a slight camber that might be causing the engine to be reducing the clearance.

Any ideas please, I can get the retaining nut off but not the idler at the moment am having to leave the old one in place although it has only done 34K.

Rover Streetwise 04 plate 34,400 miles

I have a V reg with 231k and a 53 plate with 193k and have never changed the idler on either. I did remove it on my 53 plate and induced some oil into the bearing by heating it up and submersing in oil to soften the grease.

The only way I have found to remove it is to unscrew the stud by locking the big nut with one of the M10 nuts that retain the stabilising plate. With the engine jacked up you can unscrew stud and remove the idler. I know of no other way to get is clear due the inner wing.

Thanks for the reply Bunny, I am going to leave it be then. Any ideas on the power steering leak, I left it last night in frustration. If there is a crack will i need to get the alternator off the replace it ?

This might sound daft but---------------if there is nothing in the way how about cutting a hole through the body work large enough to get the bearing through.--

Remove engine mount and jack the engine up/down to get the necessary clearance.

Thanks for the reply but I already had the engine mount off, moved it up and down as much as I could and there still was not enough space to get the nut off.

You cannot quite go high enough on 25s to get the idler clear of the inner wing, I think the crank shaft pulley hits the inner wing on the way up, but can't quite remember what stops it. On the downward side the air con pump pulley sits the front cross member and you are stuffed that way as well. If you remover the stud that the idler is retained by then you can get it out.
