Fan hub removal, How to? Options

[PaIsa]

I was planning on replacing the seal on the fan side of the main shaft but I am having some trouble getting the fan hub.

For now, I have applied some penetrant liquid on it and I will let it soak some time, but then, what is the best way to get it off.

Lightly prying it off going around? I guess that a puller would be useful, but I only have a very large puller that does not fit there. Can I apply some heat in trying to get it off?

Any other tricks or advice?

Thanks

I’m going to piss off the guys that use the flat metal or church key approach; yeah it works and 99.9% of the time isn’t going to harm anything but it is poor form.

You want all the forces kept between the hub and the crank. Steering wheel puller or pulley puller is the correct tool.

Using the flat metal and three hub bolts approach transfers the axial forces into the case.

If you’ve already removed the flywheel, there is nothing to react against the main bearing with the thrust surface. You’re now pulling the crank journal radius into the sides of the main bearings. The main bearings aren’t designed for this sort of axial force.

If you’re replacing the main bearings - oh well, who cares. None the less, not the right way to disassemble the hub from the crank.

If you have the steering wheel puller, use the right tool.
