That coupler should be splined to the crankshaft snout. Take two sections of hardwood cut at a taper and drive between the crankshaft pulley, (sheave) and back of the coupler. drive these wedges till they are tight. Use either a 2lb hammer, or better yet an air hammer with mushroom bit and impact directly in the center of the coupler from the front of the tractor. Pound your wedges in tightly again and repeat as needed.
It will let go with a "pop" but the force must be kept heavy on the wedges. You could use heat but that would chance damaging the engine front oil seal.

surely the short yoke on the crank is splined and slips in because the pulley is retained by a nut so it has to come off. could be packed tight with dirt or possibly the pully is multipiece, hard to see from picture. none of our detroits have crank drives.
did some more looking that is a garwood hardnose as well, so they did have hydraulic setups not just cable, but definitely not as common Edited by CAL(KS) - 16 Aug 2022 at 12:16pm |

I would take those pieces to a truck shop like Inland truck parts. I see they have locations in texas. They can make drive shafts. You will never find a new one and salvage is going to take time and money to find and it could be near failure also. We have inland rebuild our CV joints on our large 4wd AC tractors and build shafts when worn.

thats a Garwood blade, but they didnt make hydraulic systems. Could be a baker hard nose and cylinders, either added on or the blade was swapped. I dont have my book here to double check.

Do you know who the blade manufacturer is? CARCO? GARWOOD? . At that time all of the blades and hydraulics were aftermarket. I might have a manual....but the numbers probably won't be to helpful...pictures would be good.
