my alternative was to get 2 steel plates about 1/8th inch thick (or thin enough to fit between the hub and the case) and kinda didn't matter the dimensions but there was stock about 1.5"wide and about 4-5" long. when you remove the fan there are 3 long, i think 8mm bolts. to remove the hub, take the 2 pieces of stock and one should fit under a screw hole in the hub and the other should fit under the other 2 screw holes in the hub. screw in the bolts into the holes in the hub until they touch the stock. the stock is under the hub, over the case: between the hub and the case. gently screw in the bolts to put force outward on the hub, probably alternating tightening each bolt a little at a time. the factory tool is a u-shaped metal piece that esentially does the same thing.

let me see if i inderstand this. the metal plates are a backstop , as you screw in the bolts the hub will push forward?

Or, you could go to your FLAPS and get a 3 arm gear puller for like 20 bucks and safely pull it that way.

looks like this, but three arms. I got mine at Autozone.

(IMG:http://www.autozone.com/images/products/grn/grn47016003.jpg)

2 arm version might work as well, but 3 arm adjustable works more better.

Yes, its a tapered fit that gets held in with the single bolt.
You can heat it to expand it a bit, but I have never needed to do that.
I cant remember the torque specs, but you really dont want to go over that spec...its a threaded hold in the end of the crankshaft.. not cool to futz up.

There is also a key, dont loose it.

the special tool it a flat plate about 3 inches wide with a "U" cut out of the middle. You drop that plate down around the crank and use the bolts to push the hub off.

Good old fashioned "church keys" work well as "backstops" (your word), but ya gotta have the hardened ones. The cheap ones just bend. The torque on the bolt is 18 ft/lbs. The Cap'n

make sure you remove the big washer directly behind the bolt before you try pulling it.

Also, get some PB Blaster in a spray bottle and spray it down really good to make the job a little easier. They are under a lot of pressure. The first one I removed literally shot across the room when it finally popped.

Make sure that the bolt is threaded in all the way or it will bend. Put the "point" of the puller on the bolt. If you end up bending the bolt, let me know. McMaster sells them in 5 packs. I have 4 of them left over. :-)

Three nice thick fender washers work well. Anything that's decently strong and wide enough to spread out the load is great.

If you have a puller already, you can try that. But washers are cheaper yet than any puller. I think they're also easier in this case, because they'll hold themselves in place with no fussing.

Hope you didn't honk up the end of the case that retains the seal. BTW, be sure to replace the o-ring behind the hub. The Cap'n

Do it once, do it right. I bet this tool is still available and I further bet a good P-car or VW parts shop has them.
