Tuff Torq K57 Rebuild

[Craftsman Garage]

Hi guys, I have a Tuff Torq K57 from a Husqvarna YTH24K48 and was wondering what is involved to rebuild it? I just want it to be restored to the original speed, and I'm planning to resurface the pumps with sandpaper, but I was wondering if just resurfacing things would fix the transaxle groaning? What causes this? Also, what would be the best oil to use in this if I clean it all out? I'm hearing a lot of conflicting answers about this.

You need at least a seal kit

or if center section and pump motor(s) are a repair kit.

When disassembly pay very attention to part placement. Better yet take a lot of pictures as you disassembly. Item 36 is the motor plate that can be installed 180 out. This will reverse the transaxle operating directions.

Thanks, Do you know which filter is better, the older paper or the newer mesh one?
