How do you take off the pulley?

[G40jamie]

probably a silly question but i cant figure out how to take off my pulley to replace it with a 65mm pulley. i tried undoing the 17mm nut in the middle of the pulley but just span it round, help pleaseeee

I literally just had the sam problem so I put left the belts on and  undid the lower left bolt that lets you tighten the belts and used a torque wrench to use the tension in the belts to hold it still while I undid the pulley with a socket
Worked a treat, hope this helps if not get a leather belt and a pair of mole grips

Use an oil filter chain strap and a bit of rag around the pulley to prevent damage

Use a pipe wrench like this:

Protect the pulley, i use a piece of old tooth belt
Do up as tight as you can with the wrench opening/jaws facing you and pull towards you (makes it clamp better) and then you can tighten a little more
then undo the bolt and use the engine mount as a rest/stop for the wrench. Makes it easier.

Its really easy to do, unless you too much loctite on the bolt like i did once  

Then just do opposite when tightening up
