Hi All,
I need some help. Where can I get a VW185 tool? I did a web search but found nothing.
Thanks, Gary

Just put a normal puller on it, torque it up tight and put a bit of heat to the hub. It will pop right off.

Use a harmonic balancer puller. Available at any FLAPS for $10-$15. Looks like this:

Thanks guys. I started to use my steering wheel puller, but the feet are a little too "thick" to catch an edge.
Plus, from the pic in the 914 shop manual - it appears that this tool fits "behind" the hub & then you screw thru the hub 'til the screws contact the tool thereby applying force to the hub - not the shaft assy or engine case.
I'll snoop around my local FLAPS today after work.
Thanks, Gary

Wrestled with this problem for hours a few years back. Then I went and bought a balancer puller and had it off in 5 minutes. (IMG:style_emoticons/default/wink.gif)

I went out to the fab shop @ work this a.m. & explained what I wanted & they said "give me the dim's & we'll make one for you". WooHoo!!!
Tonight, out come my calipers. I'm gonna have it made from alum plate. Easier to machine.
Here's what it looks like in the book.

Awesome!!!
Type47, WooHoo!!! I've got all sortsa metal stock in the garage: (IMG:style_emoticons/default/boldblue.gif)
Chopped a few pieces and fit them behind the imp hub, tightened the screws a bit, added a little heat, and that bad boy popped right off!!! Then, I found a rubber packing behind the hub. It looks flat... do I need a "new" one?
I'm gettin' closer to putting the new engine in & it feels good. My first type 4 r & r. My 3 month project (yeah right) is now into the ninth month... (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/blink.gif) More $$$ than budgeted - say, times two. My piggy bank/slush fund has been emptied - twice. But hey, I'm still married & not sleeping on the couch so I must be doin' something right (IMG:style_emoticons/default/pray.gif)
Here's a couple pics.
Thanks everybody. U guys/girls ROCK!!!

When you say o ring, are you refering to the front crankshaft seal? Didn't you replace that after you put the case back together?

Yes - I mean o'ring as in "rubber packing". I am not referring to the front crank seal. When I pulled the impeller hub this o'ring was behind it. It doesn't sit in a groove or have any function that I can see. My guess is that it's suppose to be a "dust seal" or...somebody's idea of a dust seal.

Yes, an o-ring goes behind the front main seal. Not exactly sure what it does though. It comes with the engine gasket kit.

Several answers here. I used to use the tool, which isn't hard enough for repeated use. Don't even THINK about using aluminum! I now use a couple of steel "church keys" that are still around if you hit garage sales a lot. Maybe thrift stores. Those suckers are HARD! If the metal's too soft, you'll waste the case. Seen it. Next thing, you leave that o-ring out, you'll have an oil leak. It comes in the gasket set. Use it. Be sure to oil both the inner and outer surfaces of the pulley seal before installing it. Makes life a lot easier, and makes it work better. The Cap'n

An O'ring without an O'ring groove? How/what does the o'ring seal?

Might want to look before you speak. The groove is in the back surface of the hub. Cap'n Krusty, and proud of it!
