Before trying to turn the engine, remove the valve cover and the rocker arm assembly so that if a valve is stuck, you don't bend a push rod. Lub the valve stems and tap lightly with a hammer to be sure the valves are not stuck. Once the valves are all seated, use the hydraulic pressure method but with hydraulic oil, ATF or other favorite concoction in the cylinder and compressed air pressure and let it set for a few days under pressure if necessary would be my first attempt. It would help to lub and pressurize each cylinder for a few minutes, then letting the cylinder that is just past TDC sit with air pressure. Hydraulic pressure from another tractor is enough to bend or bust engine components (about 10 times high combustion pressures). [Reply]   [No Email]

When I did my grandfather's pickup I used the housejack weight to apply constant torque to the crankshaft- but not too much force to bend things. They did try drag starting that truck with no success - probably a good thing that didn't work. [Reply]  [No Email]
