| Felix is right. It's not easy.
You can get the carrier off without removing the cam though, but you will need to hold the pully and get a hold of the socket for the "special" nut that hold the pully on to the end of the cam.
Cam timing will not be too difficult if you time it up beforehand, and reset it afterwards. It's only the one pulley you're likely to disturb.
Belt tension can be done, with care by hand and patience.
Before you jump to the conclusion the leak is from the bearing carrier O=ring though, take a good look to see if it's coming from the plate that sits between the two pulleys. This is more prone to leaking and the gasket is a lot easier to replace. It's a bit tight, but you don't need to diassemble anything other than remove the belt cover.
It could also be the oil seal on the cam. |
