Mike, I"ve been rebuilding tractors for quite a while. The one thing that I almost always do when starting on a tractor is to buy manuals. I probably have 30 IT manuals covering every tractor that I have and some that I have had. I probably have more than 30 operating manuals. And I have lots of manuals written by the manufacturer. Shelves full of manuals.
It surprises me that people will look at a repair costing hundreds and not want to spend money for an IT manual.
I have been through the final drive clutch on my CA (years ago). I don"t believe there was anything unusual in reassembly. I also have repaired the hydraulics (years ago). I recall mine didn"t work because one of the spools was missing.
Mike, buy an IT manual. There are lots of small parts in that hydraulic system. It may not work because it was reassembled wrong. You absolutely need an exploded view of everything in there. You will never regret buying a manual.
