Nothing particularly hard about the job. Just is is a very different design than most other tractors.

Contrary to most of the overhaul kits out there, they are not a sleeved engine. They are "bored in block", with 20 and 40 over pistons available(blocks have a steel insert ring at the top which can be challenging for some machine shops). Make sure the radii on the crank journals are correct or it will break.

If it has any front axle except for the Carraro, parts are virtually unobtainable.
