They just bolt on and both being metal they usually corrode into position. You'll need to tap it gently all the way around the pulley continuously until it comes off.

Be careful not to damage the pulley:thumbsup

 

Cheers man, will give it ago in the morning.

 

Use a soft faced hammer if you have one :thumbsup

Or a punch and hammer GENTLY :hihi

 

Persistant tapping did the job, thanks for the help

 

Thanks for keeping us posted:thumbsup

Has the job now been completed? If so I shall amend the thread title to read (FIXED)
