Great write up. About how long did it take you to complete this rebuild? Thanks for all the information!
As you probably noticed, I ran into a couple of hiccups with the rebuild. Firstly, there is no manual specific to the K61 so I spent alot of time documenting the differences and comparing schematics. Also, as mentioned in the article, one of the motor cylinders I received had minor pitting on the machined surface and I had to get that replaced. I also chose not to try and reuse the shaft bearings, so those had to be ordered separately too. Lastly, the axle bolts were back ordered for a while so all of this set me back.
That said, there was alot of idle time, but I already had my new x540 so I wasn't in a hurry. If I had to do it again after this experience, I would know exactly what to order, and that would save considerable time. I would say with everything in hand, and the deck off and ready to go, I could do the entire job in a day pretty easily. A lot of that time includes tearing down the tractor to get to the trans, removing it, cleaning the trans, scraping all of the old sealer off the halves, and afterwards waiting for the sealer to cure, and bleeding the system. The actual time to swap the parts once the trans is clean and on the bench is not very long at all.
I will however warn you to take your time, make sure you are meticulous with the cleanliness of your work area, and be very careful during disassembly. Lay all of the components out on a table with newspaper in the order removed. If you flip around anything by mistake, it could be a very expensive learning experience. I will say that if you are the least bit handy and are detail orientated, it's not a bad job at all, but you just have to do the job right to get the value out of your investment.
I hope this helps. If you have anymore questions specific to this job, it would be better to respond on that thread, as I don't monitor this site very closely.
