Removing a fan on a NEFF oven?

If you need to remove the fan to change the element you must have a double built under oven with a half moon shaped element where the fan blade covers the fixing screw? Never had a problem getting the fan blade off, firstly I take it you know it is a left hand thread so undoes the opposite rotation to ordinary nuts? Hold fan blade with pliers, undo nut clockwise, remove washer between nut and fan blade, hold shaft on flat with pliers or pipe grips, rotate fan blade on shaft till it spins freely (use wd40 if required) pull blade off shaft using 2 pairs of pliers one on each side of fan.Cheers
