Red face what special tool is needed to press off the gears on 914 crank?

Starting the rebuild of a 1975 914-2L spare engine. Got down to the crank and the stupid bearing is behind the intermediate (timing) gear driving the cam gear. Does anyone know how to remove the gears (brass distributor drive and steel timing gears) using a press (have a 20 ton press) but no collars to grip the timing gear while pressure is applied to the nose of the crankshaft. Does one cut off the bearing before the gears can be pressed out? What is the tool (part number and source for me to order one?

I tried a 2 leg puller and it didn't grip well enough to work. Also I think the damn parts are rusted together over the years (30). Need to get the proper tool for the press to work.

Heat up the gear with a torch and use the puller to get it off. Be careful not to stracth the crank up. You can rent them at autozone for around $10 or so...

Or you could just buy one for about 19.00 at Autozone. I used a 3 prong puller purchased at Autozone for about 24.00. I still have it too. Use it all the time.

You can buy a set of the pullers, 3 different sizes, for around $20 from harbor freight. I picked up both the 3 leg and 2 leg sets.

Thanks, my local Autozone didn't have the right size pullers. The gap between the bearing and steel gear is about 4.5 mm, most of the jaws of the pullers are too thick to get inside the back of the gear for a good grip. I am thinking of buying some steel sheets 0.017 inch thick hard alloy (4" wide by 8" long) and drilling a 60mm diameter hole through 2 pieces centered to make my own collar for the press to work.

You can take it to shop that has a bearing press and remove it. To install use torch or oven method. Thats what I did.

I found what I was looking for in link:
http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=3979

It's called a bearing separator and used with a press like I described.

Thanks for all the other answers.
