I own a 1500D but haven't had to resleeve it yet. However, many years ago when I was teach Vo Ag, a kid brought an old Farmall in to rebuild. I made a sleeve puller out of scape steel and a long 1" diameter bolt. It worked pretty well. On the Farmall, once the sleeves was pull ~ 1/2" or so, they then came right out.

On car engines I use a small rubber mallet to nudge them in any direction they'll move. Usually after a few taps the cylinder is loose enough to pull up. In my case there is nothing holding the cylinders in except a paper gasket at the bottom of each cylinder.

I pulled a sleeve out of a YM2000. I made it out of angle iron and a piece of all thread rod. It worked fine.

Have you tried chilling it? An icepack, or maybe even dry ice, may help it slide out easier.

Is the angle iron on the bottom slightly shorter than the sleeve OD? If it is ,more torque on the nut. With all the torque on the nut you are comfortable with, tap the side of the block, TAP with a brass hammer.

I've never had to do this, don't need to now, but for future reference can someone post a picture so I can visualize how this works.

Thanks,
