Look around. I needed one for a leaky one on our Deere 7H17. The Deere dealer found one for $575. Our Grandstand started doing the same thing. Leaking, caused by bearings going out and too much play. We called Parker? I think it was. The numbers will tell you everything. The only difference was the Deere one was for through bolts and not a threaded flange. We fixed the Toro first because it gets used more.
