I picked up a WD45, from my neighbor, for the tires this last summer. They work fine on my WD (working tractor).

Upon looking at the tractor, it is almost complete. I remember the tractor running about 10 years ago. The previous owner always had trouble with the hand clutch (probably just shimming). The previous owner took out the spark plugs, removed the starter, clutch cover and the gearbox cover. And this is how it rested for almost 10 years. This is how I now have it.

Since the spark plugs have been out for years, I am looking for suggestions on how to free up the motor with out damaging it. It will be a working tractor doing more than it should (typical small farm).

Use the fore mentioned penetrants, I also like marvel mystery oil, and fill the cylinders and let it soak. When it comes to loosening the pistons with a hammer, I use a piece of a sawed off fence post, also known as "Roger Welsch's Custom Piston Remover". If the piston is below top dead center, I hone out the rust with a ball hone. Less resistance once the piston starts to move. Good luck. Brian

I just finished a stuck A. With only takeing off the valve covers and oil pan, use two 6 ton jacks and lift on each side of the worst cylinders. Use a wood dowl through the spark plug whole and feel the cylinder walls for rust. The dowls can be used for scraping the cylinder walls. The WD is light weight, you may have to tie it down to get enough pressure. Use the jacks to cause motion in one direction then the other direction. If you paid the pritcher sunday, it will break loose. Good luck and tells us what happens. Dave and Mary Bowers

Use a good pentrating oil Blaster, Kroil, etc allow the oil to soak in for at least one week making sure the tops of the pistons remain covered. Take a peice of 2x4 and a large hammer and tap the tops of the pistons if they don't move soak the pistons for another week and tap them agin. It will take time even then you may have to take the engine to a machine shop and have them pressed out.
