Default Removal of crank pulley

Hi,

I am having real trouble getting the crank pulley off my 1.6L.

I have the bolt off, and the timing belt, but the pulley will not slide of the crank.

Any suggestions?

Default hammer

Okay...so, a huge *** hammer and a block of wood where??

I guess the thing is "how" do take that damn thing off.

I dont want to take a screwdriver or something behind the pulley as I might score something that I shouldnt.

At this point i guess since I havent "scored" Im just f'd...

Lemme know what you guys come up with.

What about a steering wheel puller? On my 1.8 it's 4 bolts then it just comes right off. :gay:

Mine was tough when I took it off. I can't remember exactly how it came off eventually, but it involved a hammer and a block of wood. It's a pretty robust piece, and shouldn't take TOO much pounding to knock it loose, unless it has really rusted on.

Be careful with a puller. It can damage the edge of the pulley.

Okay...I suppose some elbow grease. Did you just pound on the thing with a block of wood above it or??

Wait, so are you talking about the pulley that drives the accessory belt, or the pulley that drives the timing belt? I will assume that you are talking about the timing belt one as it can be a pain to come off. What I have done to take it off is spray it down with penetrating lube and let it sit awhile. then I pryed around the edges of the pulley gently. I say gently because the lip on the pulley breaks easily and I can say this from first hand experience.

edit. Oh and im sure a puller would work well too.

I was assuming the trouble was with the pulley, and not the cog. Just please don't try a steering wheel puller.

Default Yes the timing "gear"

Yup its the gear (with teath) that the woodroof key slides into and attaches to the crank.

So I suppose either spraying with alot of wd-40 or something and/or using puller.

Damn timing gear.

if you have two big prybars, get it from both sides and wiggle it loose, it can be a tight fit. If it is really tight, go from multiple angles and hit it some more.

The Mazda Helms book says to use a steering wheel pulley. So use a steering wheel pulley. Find the smallest one you can find so the "hook" will fit behind the gear.

Or make your own pulley

There's not really anything to "score" behind it.

Sorr if my posts have been confusing. The only trouble that I see with a puller is in removing the pulley, and not the timing gear/cog. The problem is in positioning the grips, in that is misplaced, you can easily destroy the accessory pulley. That's all. The timing gear/cog is whole different ball of wax.

Hope you've had good luck with this!

I think he's talking about the cog.

As for the accessory pulley, mine came right off with a gentle tap after removing the 3 bolts.

Default Yup the cog

Yup its the cog.

Anyhow, in the pick I also see the same damn build up of gunk, and oil that I have. Some it is really bad around the AC compressor.

To do a complete job, and clean that crap off, where does that come from a leaky oil pan gasket? and if so is it a bitch to replace??

I figure that while I **** off, I might as well do it all right and clean it up.

Your two cents on this is welcome as well.

That stuff accumulates from all over the place. Can be the crank seal, or either cam seal. Could be the valve cover gasket, but that's more likely to show up on the sides and back of the engine. But since you're in there already, I assume you're planning on changing all those. If it is the oil pan gasket, yeah, it's a pain to replace I've heard, but I haven't done mine with the engine in the car.
