Hi, I am having difficulty removing the cylinder block from a 1944 B. All of the fasters listed in the service manual have been removed. This includes the six bolts holding it to the frame and all of the base bolts. The oil line has been removed. The head is off. The pistons and connecting rods are out. Methods tried so far include: 1.) Putting a wooden block on various places on the cylinder block and striking it with a 2 pound hammer 2.) Putting a small hydraulic jack between the lip on the head side of the cylinder block and the crankcase and applying moderate pressure 3.) Heating the cylinder block up with a rosebud torch (this made an awful mess!) 4.) Putting a floor jack under the front of the block and applying pressure until the tractor came up into the air. 5.) Squirted penetrating oil all around the base gasket. 6.) Applied moderate side pressure using a crowbar between the frame and the block.

Does anybody have any ideas? I decided to stop before something breaks. Also, does anybody have any input on what NOT to do? Thank you.

Greg

Greg, Did you remove the two bolts on the side below and to the rear of the spark plugs? These are on the outside of the frame just in front of the flywheel on one side and the pully on the other and go into the side of the block.

Bguy - Yes. The two on the side of the angle iron were removed as well as the four on the bottom of the angle iron. I rechecked, and every bolt has been removed.

On the sides and bottom of the block there are flat pads where the frame and block bolt together. The only thing I can think is that these points have corroded together. I know on mine it was a very tight fit on the sides. If it were me I would support the tractor under the crankcase with a jack stand and separate the frame and the crankcase. The block will then be just hanging out there. That's the way I did it.

Greg:
Several years ago I also tried to remove the block from my 44 B. I would agree with the previous post about unbolting the frame. I had all the bolts out also and just like you could'nt get the block to come loose. If I remember right once I got the frame off I found 2 more bolts that were hidden. Hope this helps.

Thanks for the tips. I'll try this after Christmas.
