use a good penitration oil and leave over night then using a wood mallet tap all around the boss untill it frees off
anything mounted onto the crank and never removed will be a sod to get off as the rust acts like super super glue which is super and will take some gentle easing
if you can find a pully puller brill
or make one out of a steal bar drill 3 holes - 1 centre then 2 in line with the boss holes
the 2 out side holes you bolt to the boss with space between the bar and boss and the centre hole is used to put a longer bolt through which will sit on the crank with the nut on the inside
turn the centre bolt while having a spanner on the nut (cetre bolt again) and this should pull off the boss square/ straight
if that makes no sence i will try to draw a diagram up later and post that aswell
cheers neal but i had a puller on it for about a week already heavily doused in penetrating oil...and nothing. took mr angry grinder to visit the blade boss today and found out that the boss was in 2 parts, one part was the pulley that had the rounded off hex grub screws and the lower half the actual blade boss. lots of cutting later and i now discover the shaft is smaller than the bosses i usually use on my mowers. big P.I.T.A!
thanks for the reply anyway ; )
