I own a 1969 Ford tractor 3400. I do not know the model number of the loader, (730?). The tag on it has, component #19-527 and serial #D 543293. The hydraulic pump drive shaft goes from the hub assymbely,(#C5NNN879A) that is bolted to the pulley on the crankshaft, through the front axle pin, and on to the hydraulic pump. The shaft is 7/8" DIA. and 8 1/2" inches overall length. One end has 13 splines that fits hub assymbely on crankshaft and the other end has a flange on it. The flange measures 3 3/16" inches across with four threaded 7/16" bolt holes. The bolt holes measure 1 15/16" center to center straight across or 2 3/4" center to center diagnally. The other half of the flange has 13 female splines that fit onto the pump and with four bolt hole sleeves mounted in rubber and bolts to the flange on the shaft. I can"t really tell, but it looks like the shaft might have had splines on both ends and somebody may have welded the flange onto it, (maybe not?). Can anybody tell me the part # of the shaft, flange or what parts manual I need to buy in order to get these #"s. I have looked at Yesterdays Tractor and Antigue Tractor sights but none of them give me the specifications of the shaft and don"t even list the fange. Please help me, it is snowing heavely and I need to get this tractor running.

Thank You any and all for your help! Rusty.

Remove it and take it to any good tractor dealer and they should have them or be able to get them for you. Your problem is common with those hyd pump drives. A NH?FORD dealer is your first place to look but other dealers will have or can get them. Just be sure to take the shaft with you so they can match it up, its also good to replace the part that bolts to the crank pulley since it wears out at the same time
