crank pulley removal

[Purdy Swoft]

If you still have the original ratchet nut, actually a bolt that holds the crankshaft pulley in place you will need a 1&3/8 socket and pull handle or an off set box end wrench. The ratchet nut can be a pain. The easiest way that I have found to remove the ratchet nut is to let the end of the pull handle or wrench rest on the drivers side of the frame and let the starter do the work. Just hit the starter button-pedal with the ignition switch off and it will spin the ratchet nut right off. As Carl said, if you've got the one piece pulley it will be more fun. With the one piece pulley the easiest way is to use a chisel and hammer or just a hammer and break the outer part of the pulley where the belt fits, spokes and all off. If you've got an original type one piece pulley, it will be made of cast iron and breaks easily. No worry about straining or breaking the crankshaft because the crankshaft on the model A is forged. Otherwise it will be necessary to remove the radiator, front spring U bolts, crank guide, accellerator assembly on the rear of the engine, remove the front motor mount yoke bolts, remove two of the rear motor mount to engine bolts and loosen the other two. Then you can place a piece of wood between a jack and the oil pan and proceed to carefully jack the engine up for clearance tro remove the pulley.
