30 318 tiller

I have two #30 hydraulic tillers, one came off a 216, but found out I was rooked and the pump/motor/tine shaft are all junk. It has a large spring on top of it with a hand crank on it. The one I just picked up last weekend doesn't even have the paint worn off the underside yet doesn't have...

I'm looking for the motor shaft and tine shaft from a 30 tiller, its a long shot, but maybe someone's motor went bad and the shaft is good. Thanks
