New Cub Cadet owner needing some help

[BradH]

Hello,
A few weeks ago my family and I bought two Cub Cadets to use around the farm and our pumpkin patch we run in the fall. We bought a 1650 and a 149, both with 50 inch decks, and a snow blade and weight box for the 1650. Got them both delivered for 600 dollars. The 1650 had been the primary mower but needed a new hydro gasket. The 149 was bought for parts, but does run for a few seconds at a time. I think the guy said something about swaping the rear out to fix the 1650. Seems like more work to do that than just splitting it and changing the gasket. Anyway, I split the 1650 and changed the hydro pump gasket and got it all put back together. No leaks so far so I'm plased.
Now here's where the trouble comes in. I also changed the oil seal on the input shaft on the pump. I figured it wouldn't hurt to change it while I was there. Just in case that was the source of the leak. The trouble it when I knocked the seal out I also knocked out the needle bearing. There were neelde bearings and an O-ring. Not sure how it happened. I am actually legally blind so I may have just hit the wrong thing not realizing what I had the punch on, try not to judge me too harshly. So anyway, it's all back together for now and nothing is leaking. I called the local CC dealer, also the IH dealer on Monday. They say that bearing is a non serviceable part and you have to buy a charge pump kit. He then priced me a kit for 700 dollars. So my real question is, does anybody know where to get that bearing and whatever else goes in there with it? Also, how does it all fit back together? Sorry, but pictures won't help me much, as I said I'm partially blind. Feel free to reference them though, I can surely get somebody to help if I need too. Appologies for the long post, I tend to ramble on sometimes. And thank you for the great resource here on this forum. I'm glad to finally have a GT so I can be a member. I've been wanting one for several years now.
Thank you,
Brad
