it is on a tappered shaft that has got splines on it so it should come off rather easily but for the love of me i cant get the fing thing off!

i have tried soaking it in an excessive amount of CRC and then use a precision tool aka hammer to get it to move in either direction but nothing happens! Im looking to see if anyone has a big ass puller i can borrow to get it off or If you know how to get it off shed some light on the situation, Hell if come and get it off if ya want :P\
thanks
