258 Fan Removal Help

Hey all,
I am in the process of replacing my timing gears and chains, and am working on removing the front engine components. My guide tells me to simply remove the fan and pulley, put I don't know how to go about it. There are four bolts that hold the 'viscous drive fan' blades to the disc in front of them, which has a 'bimettalic coil' on it. But removing the fan blades wouldnt really help anything, the rest of the assembly would still be there, and the fan blades wouldnt even come out.

sooo....do i remove the 4 bolts that hold the pully to the motor? any suggestions much appreciated

My timing chain is really slack, so much so that i can barely even set the timing because it jumps around so much. Im also doing my RMS, so thought I'd knock em both out together....

okay, update....
I have got the belts off, and have taken out the 4 nuts on the pulley....still doesn't budge. Do I need a puller to pull it out, or am I missing something?

There is about a half inch shaft coming out of the pump going into the fan. A tap with a rubber mallet should loosen it or just wiggle it.

A tap on the shaft? Which way? Into the engine? That doesn't seem right... sorry, still confused I can't tap the end of the shaft because it still has the big disc on it outside the fan blades....

All the damn manual says is to remove the fan. So easy...The picture shows where I'm at right now....

Looks like you've removed the 4 nuts necessary to remove the fan. Only those 4 nuts hold it on so maybe it is stuck with rust.

are the fan blades and pulley one unit? What should i pull on to get em out? I need to remove the pulleys as well, but it looks like those are the only 4 nuts holding them on. Is that correct? Should I be able to pry the pulleys out?

thanks for the help

I got it! The fan clutch mounting plate was way stuck to the pulley. I slowely drove a flathead in between working my way around and it finally popped off. Thanks!
