well ive had the new one in the glove box for a while so i thought id fit it lol ...30 mins work :lol:
remove fan cover to aid access to tensioner
with a 15mm spanner place on the wheel bolt and lever back, so you can remove the fanbelt
undo the tensioner bolt anti clockwise and remove from engine block
place whole unit in a vice ,and with a 15mm socket or spanner undo bolt clockwise removing wheel from the unit
place wheel on a hard surface ,and with a fine screwdriver or pick remove circlip retaining the bearing in place
once circlip is removed place wheel on top a vice with enough space for bearing to drop .i used an 11/16th socket on an extion bar tapping out the bearing circlip side ,as there is a shoulder on the other side.
once bearing is removed .replace and refit in reverse
the new bearing i got of ebay for a few quid
too much time on my hands lol hope it helps someone
