I think some noise from the lift is normal...all of my tractors with hydraulic lift do that.
I replaced that cylinder block assembly along with the fixed swash plate...my non-ported pump was from a 125 so I wound up using more of that one than I wanted to because of differences between the older pump and the new. Somewhere I have a list of all of the differences between ported and non-ported pumps that I discovered. My advice to you would be to try to find a non-ported pump from a late QL or an 82 series, that way you'll have to use less parts from the non-ported pump. Be sure to follow your service manual, and clean everything extremely well before reassembly. A parts washer is a great idea. I'd wear rubber gloves when reassembling also. Let me know of any other questions you have, I'll try to help. The pump and motor cylinder block assemblies are the same, (I think) so you might even be able to combine 2 broken units.
